At $WCH (+0,96 %) I have also bought in. I think the share is at an interesting chart level here. I see a breakout above €87 as a strong signal and I am betting on this with leverage 6.

I have a question for the community, maybe some of you here are a bit more familiar with a few tax issues that are bothering me.

I transferred my custody account from Onvistabank to ING in 2025. As there were sanctioned securities in my Onvistadepot, the custody account still exists and the 2025 loss pot was not transferred to ING. If I have now realized gains at ING in 2025, can I request a loss declaration from Onvista and claim this on my tax return for 2025?

On Thursday, I have withdrawn from the values $WCH (+0,96 %) and $AFX (+3,69 %) at a loss, these losses were also shown in the loss pot at ING. Now, on Friday, I sold my $ROG (+1,08 %) with profit on Friday, but I paid the full rate of capital gains tax on the profits and the loss pot remained unchanged.

Does anyone have any experience with this? In my opinion, this should be offset directly.

I know this is a very dry topic, but I would be grateful for any feedback 😁

Good morning, dear getquin community.

Over the past few weeks, I’ve been taking a deep dive into the battery and energy storage industry—its entire value chain, the major players, and the hidden champions behind the scenes. Today, I’d like to share this knowledge with you @Tenbagger2024 and show how individual technologies are coming together to form a cohesive energy system. I look forward to hearing your perspectives on this.

It’s no coincidence that Warren Buffett $BRK.B (+0,53 %) Berkshire Hathaway. He recognizes early on where real value is created and what role chemical processes play in the development of modern energy and storage systems. That is precisely where it will be determined how efficiently batteries and fuel cells will be produced, operated, and recycled in the future—and who will profit from this transformation in the long term.

Personally, I’m not yet as broadly positioned in this sector as I’d like to be. I’ve already invested in some segments, but the entire value chain still offers enormous potential—and that’s exactly what I wanted to better understand through this analysis, among other things.

I’ve deliberately avoided mentioning personal favorites @Multibagger to keep the analysis neutral. If you’re particularly interested in certain companies, topics, or questions, feel free to mention them here in the comments. I’m open to feedback, additions, and discussions, and if any key players are missing in a particular area, I’ll be happy to add them later. This post ended up being a bit longer because I wanted to present the topic comprehensively and clearly. If you’re primarily interested in the companies, the value chain, and the shovel manufacturers, you can skip ahead to points 13 through 16.

Perhaps Part 2 will cover fuel cells, if that’s what you’d like? I wish you all the best of luck with your investments and, of course, a wonderful Sunday.

2️⃣.Topic and Objective of the Article

The battery industry has long been more than just cell manufacturing or e-mobility. It is at the center of a global structural transformation that is redistributing energy, technology, and capital. The goal of this article is to understand the battery as a complete value chain—from raw material extraction through material technologies, production, and application to recycling and recovery.

I will show how genuine value is created along this chain, which industries benefit directly from it, and why the battery industry is becoming a central link in future energy systems. At the same time, the goal is to view the whole as a strategic model—a convergence of technology, economics, and sustainability that extends far beyond the mobility sector.

3️⃣.Basic Principle of the Battery

At its core, a battery is a chemical energy storage device that stores electrical energy in the form of chemical compounds and releases it again when needed. It consists of three main components: an anode, a cathode, and an electrolyte. During charging and discharging, positively charged ions move back and forth between these electrodes. This generates an electric current that can be used to power vehicles, supply machinery, or stabilize energy in grids.

The basic principle is reversible. This means that energy can not only be drawn from the battery but also fed back into it. This simple yet highly effective reaction makes batteries one of the central building blocks of modern energy systems. Thanks to advances in chemistry, materials technology, and manufacturing, performance is steadily increasing, while weight, charging time, and costs are continuously decreasing.

4️⃣.Applications

Today, batteries are far more than just a power source for electric cars. They are the backbone of modern energy systems and key to stabilizing renewable power grids. Their applications range from electric mobility to stationary energy storage to industrial and digital applications.

In the mobility sector, batteries enable the transition from internal combustion engines to electric drive technology and form the foundation of new vehicle platforms. In the energy sector, they serve as buffer storage for solar and wind power, balance out grid fluctuations, and ensure a reliable supply during peak times. In industry, they ensure supply reliability, efficiency, and emergency power solutions, while in data centers they are increasingly being used as emission-free backup systems.

In addition, new areas of application are emerging in aviation and maritime transport, in household and building systems, and in microgrids that supply remote regions or industrial parks with energy independently of the central grid. Batteries are thus a universal energy storage medium that connects sectors and lays the foundation for flexible, decentralized energy architectures.

5️⃣.Battery Life Cycle

A battery goes through a clearly defined life cycle that extends far beyond its actual use. It begins with the extraction and processing of raw materials, continues through cell and system manufacturing to the active use phase, and ends with the recovery and recycling of the materials.

During the production phase, active materials and cells are manufactured from raw materials such as lithium, nickel, manganese, cobalt, graphite, and copper. These cells are then assembled into modules and complete battery packs. During the usage phase, the batteries provide energy for years in vehicles, energy storage systems, or industrial facilities.

Once the end of their service life is reached, the second cycle begins. Cells that are still powerful enough are reused in so-called second-life applications, such as stationary energy storage systems. Finally, the recycling process takes place, during which valuable raw materials such as lithium, nickel, and cobalt are recovered and fed back into the production cycle.

This closed-loop material cycle is the crucial step toward a sustainable battery economy. It reduces dependence on primary raw materials, lowers environmental impact, and makes the entire value chain more resilient in the long term.

6️⃣.Future Trends

The battery industry is facing a period of massive technological and structural change. Progress is shifting from a focus on sheer capacity increases toward efficiency, sustainability, and material independence.

A key trend is the shift toward solid-state batteries, which—thanks to solid electrolytes—are safer, more compact, and more powerful than today’s lithium-ion systems. At the same time, silicon anodes are gaining importance, as they enable higher energy densities and shorter charging times. Sodium-ion batteries open up new possibilities for cost-effective storage solutions, particularly in applications where weight and energy density are less critical.

The digitization of batteries is also advancing. Smart battery management systems analyze the condition, temperature, and state of charge of each cell in real time. This not only improves safety but also extends service life and optimizes operation.

On an economic level, the industry is moving toward vertical integration: manufacturers are securing raw materials, energy suppliers are building their own storage facilities, and technology conglomerates are investing directly in manufacturing capacity. At the same time, political pressure is growing for a circular economy, recycling, and carbon neutrality.

The future of batteries thus lies in a combination of new materials, smart control systems, and closed-loop systems. Those who successfully integrate these three elements will play a decisive role in shaping the dynamics of the energy market in the coming years.

7️⃣.Raw Material Base and Development

The battery industry begins at the source of raw materials. Lithium, nickel, manganese, cobalt, copper, and graphite currently form the basis of nearly all high-performance cells. These metals determine the energy density, stability, and service life of every battery. At the same time, they are the most sensitive part of the value chain, as their extraction, processing, and supply determine costs, sustainability, and geopolitical dependencies.

A significant shift has taken place in recent years. Companies and governments are investing in new mining areas, recycling facilities, and alternative materials to ensure a secure supply. Lithium and nickel, in particular, remain key materials, while cobalt is increasingly being replaced. Graphite is undergoing a transformation toward synthetic and recycled forms, which are intended to reduce dependence on China.

The trend is clearly moving toward material efficiency and a circular economy. Instead of constantly opening new mines, closed-loop systems are emerging in which raw materials are reused multiple times. At the same time, alternative cell chemistries are coming to the fore, relying on abundantly available elements such as sodium, iron, or silicon.

This shift reduces costs, lowers environmental impacts, and increases the independence of entire economies. The raw material base of the battery industry is thus transforming from a linear supply chain into a global, circular material network that combines technology, recycling, and sustainability.

8️⃣.Value Chain

The battery industry follows a clear industrial logic that extends from the extraction of raw materials to the recycling of materials. Each stage in this chain creates its own value and is, at the same time, a prerequisite for the next.

1. Raw Material Extraction – Mining and extraction of lithium, nickel, manganese, cobalt, copper, and graphite from mines and salt lakes. This stage determines the cost structure and environmental footprint of the entire battery.

2. Refining and processing – Processing raw materials into battery chemicals, such as lithium hydroxide or nickel sulfate, which are used in cell production.

3. Materials technology and component manufacturing – Production of cathode, anode, and electrolyte materials, as well as separators, conductive foils, and binders.

4. Cell production – Assembling the materials into electrochemical cells through coating, stacking, and sealing. This step determines capacity, safety, and quality.

5. Module and pack manufacturing—Cells are assembled into modules and complete battery packs, including the battery management system and cooling.

6. System integration – Installation of battery packs in vehicles, energy storage systems, or industrial equipment. This is where the battery, software, and power electronics come together.

7. Use and operation – The battery’s operational phase spanning several years. Digital monitoring and predictive maintenance extend its service life and efficiency.

8. Recovery and Recycling – At the end of the life cycle, materials such as lithium, nickel, cobalt, and graphite are recycled and returned to the production cycle.

Together, these eight stages form the complete industrial cycle of the battery industry. Value is created at every stage, but it is greatest where technology, energy efficiency, and recycling intersect. This is the point at which a supply chain becomes a true value-creation system.

9️⃣.Value Creation Vectors in the Battery Industry

The battery industry is shaped not only by production processes but also by several overarching forces that act like vectors, cutting across all stages of the value chain. These vectors determine which companies remain at the forefront and where value is concentrated in the long term.

1. Technology Vector

Advances in cell chemistry, materials science, manufacturing, and software integration. Companies that scale up in these areas reduce costs and increase energy density, safety, and service life.

2. Digitalization Vector

Data management, condition analysis, cloud-based battery monitoring, and predictive maintenance. This level connects physical systems with AI and makes operations and recycling more predictable.

3. Sustainability Vector

Circular economy, carbon-neutral production, ESG standards, and material recycling. Companies that lead in this area secure long-term approvals and capital.

4. Finance and Investment Vector

Capital flows from government subsidies, private funds, and infrastructure programs that finance manufacturing capacity and research.

5. Infrastructure Vector

Construction of gigafactories, recycling centers, charging infrastructure, and energy storage facilities. This foundation is crucial for scaling up and ensuring supply security.

6. Geopolitical Vector

Location decisions, trade agreements, raw material dependencies, and security interests determine who has access to strategic materials and markets.

These vectors operate simultaneously and reinforce one another. The true dynamics of the battery industry emerge where technology, sustainability, and capital are intelligently intertwined. This is the axis where innovation, returns, and resilience converge.

🔟.Value Creation as a Cycle

The battery industry is increasingly evolving from a linear supply chain into a closed-loop system. Energy, materials, and data flow continuously between production, use, and recycling. The goal is to conserve resources, minimize losses, and increase value throughout the entire life cycle.

The cycle begins with raw material extraction and proceeds through material development, cell manufacturing, and integration, all the way to use in vehicles, energy storage systems, and industrial facilities. After the operational phase, materials are recovered and reused in new batteries. This physical cycle is complemented by a digital data cycle in which all relevant information about the condition, performance, and age of each cell is stored and analyzed.

This creates a system that optimizes itself. Data from operations flows back into research, design, and recycling, making new generations of batteries more efficient, safer, and more sustainable. This combination of physical and digital cycles is the key to genuine value creation in the Battery Industry 4.0.

1️⃣1️⃣.Macro and Micro Levels

The battery industry operates on two interconnected levels that drive and stabilize one another. At the macro level, global structures, political programs, and economic frameworks take shape. At the micro level, technological, chemical, and process-related developments come into play, making these larger trends possible in the first place.

The macro level encompasses everything that drives the industry as a whole: geopolitical interests, energy policy, subsidy programs, trade, infrastructure, and capital flows. This is where the course is set for where gigafactories are built, which countries secure access to raw materials, and how nations reduce their energy dependence.

The micro level describes the technical reality: cell chemistry, material innovation, manufacturing technology, software integration, and recycling processes. This is where actual progress takes place. Every new battery chemistry, every improvement in energy management, or every reduction in the use of rare metals alters the larger system in the background.

Both levels are intertwined. Political decisions and capital flows at the macro level enable technological developments at the micro level, while technological breakthroughs, in turn, trigger new markets, trade structures, and investment cycles. It is precisely at this intersection—where technology, politics, and the economy interact within a closed system—that the strategic potential of the battery industry emerges.

1️⃣2️⃣.The Significance of Battery Industry 4.0

Battery Industry 4.0 stands for the complete digitization and networking of all processes along the value chain. It combines production, energy, data, and sustainability into a single intelligent system that is controlled, monitored, and optimized in real time.

At its core is the integration of physical equipment with digital platforms. Every cell, every machine, and every process provides data that is analyzed using AI and analytics. This creates a self-learning system that detects errors early, ensures quality, and extends the service life of the batteries.

In manufacturing, automated lines, robotics, and machine learning maximize efficiency and precision. During operation, cloud services and IoT sensors enable continuous condition monitoring, which optimizes maintenance, safety, and performance. At the same time, environmental data is collected to make CO₂ footprints transparent and verifiable.

Battery Industry 4.0 is therefore not just a buzzword, but the transition to a fully integrated, data-driven energy industry. It lays the foundation for scalability, cost-effectiveness, and sustainability, and connects research, production, use, and recycling in a closed digital loop.

Visual Overview of the Battery Value Chain

To make the entire structure more tangible, I have divided the battery industry system into three levels:

1. Macro level: global value creation, energy policy, raw material and production networks.

2. Micro level: technological processes, material cycles, and innovation axes.

3. Overall Model: the integration of both levels into a closed-loop system that connects production, use, and recovery.

This diagram illustrates how linear supply chains evolve into a circular, digitally controlled energy system—the very DNA of the Battery Industry 4.0.

1️⃣6️⃣.Energy for humanoid robots: the next evolutionary stage of application

The next industrial revolution is no longer taking place solely in data centers or vehicles, but in the convergence of humans, machines, and energy. Humanoid robots symbolize this transition. These are systems that must think, act, and be self-sufficient. Their energy source is what makes them functional in the first place.

This is where battery technology, microgrid systems, and smart energy distribution intersect directly with artificial intelligence. Power density, longevity, and energy efficiency determine how autonomously these machines can operate. Whether in industry, healthcare, logistics, or everyday life, the stability of their energy supply is becoming a strategic factor for entire value chains. Next-generation batteries, solid-state systems, and mini fuel cells form the foundation for this. Companies that develop or supply these technologies are not only creating products but also building the infrastructure for a new form of intelligence that is energy-independent, networked, and scalable.

16.1 Technical Basis: What a Humanoid Really Needs in Terms of Energy

A humanoid robot is, at its core, a mobile energy system. It must walk, grasp, lift, balance, communicate, see, think, and remain safe while doing so. All of this requires a constant supply of energy.

Key requirements: high energy density with low weight, short-term power spikes, thermal stability, energy recovery, and long operating times without manual recharging. Currently, the energy requirements of humanoid robots range from 500 watts to 2 kilowatts, with energy storage capacities of 1 to 5 kilowatt-hours. A system is only considered suitable for industrial use if it can operate autonomously for several hours and recharge itself or swap modules.

16.2 Storage Status Today and in Five Years

Today:

Lithium-ion systems (NMC, NCA) dominate due to their high energy density.

LFP cells excel in safety and lifespan.

In five years:

Silicon anodes will increase energy density and charging speed.

Partially and fully solid-state batteries will improve safety and stability.

Combinations of batteries and fuel cells will emerge for continuous-load applications.

As a result, the robotics energy market is shifting toward modular, interchangeable high-performance cells with active thermal management and smart controls.

1️⃣7️⃣.Takeaway

The battery industry has long since evolved from a standalone solution into a multifaceted ecosystem in which materials, technologies, data, and energy flows are intertwined. Hybrid energy systems that combine batteries, fuel cells, and renewable sources are no longer a vision but a reality, evident in data centers, industrial parks, and transportation systems around the world. What matters most is no longer just how energy is generated or stored, but how it is intelligently controlled and integrated into existing grids. This is precisely where the real added value lies: in the ability to synchronize energy flows, data systems, and capital flows. Perhaps this is the point at which it will be decided in the future who will shape true energy autonomy—those who produce energy, or those who can control it precisely?

The weak dollar exchange rate against the euro for months now is having a noticeable impact on German companies. Numerous companies are expecting significantly lower profits in the second quarter and a continuing burden from the unfavorable exchange rate.

At the end of February, the euro was still trading at around 1.05 dollars, and some were even expecting the currencies to reach parity. But the opposite has happened: Since the threat of high US tariffs in March, the US currency has been weakening, with one euro currently costing 1.17 dollars - a 14% appreciation of the euro.

Large companies with strong foreign operations are particularly affected by this. "In the Dax, that's almost all of them," says Jörg Held, Head of Portfolio Management at the fund company Ethenea. He warns that the weakness of the dollar is "becoming a measurable profit killer". Many experts believe that the negative impact of the currency constellation will not disappear for the time being.

Companies' results will come under pressure in two ways: products from export-oriented companies such as $P911 (+0,56 %) Porsche become more expensive when their price is converted into dollars. Their competitiveness is weakened because competing products from companies in other currency areas with lower exchange rate fluctuations become comparatively cheaper.

"A ten percent appreciation of the euro reduces the profit growth of European companies by three to five percentage points over the course of a year," calculates Ulrich Stephan, Chief Investment Strategist at Deutsche Bank.

• BASF
  $BAS (-0,53 %) has lowered its forecast for 2025 by eight percent and now expects an adjusted profit of between 7.3 and 7.7 billion euros. Currency effects already depressed earnings in the second quarter. The negative effect on earnings is primarily due to the translation of earnings generated abroad into euros. In February, the world's largest chemical company was still expecting an exchange rate of 1.05 dollars per euro for the year as a whole. BASF is now assuming 1.15 dollars.

• SAP $SAP (+1,41 %) sees a "significant headwind in the profit and loss account this year" due to the development of exchange rates, as CFO Dominik Asam says. Every percentage point by which the dollar depreciates leads to a loss of around half a percentage point in growth for SAP.

• Wacker Chemie
  $WCH (+0,96 %) expects the current exchange rate level to continue. The rule of thumb within the Group is that a depreciation of the dollar against the euro of one dollar cent will have an impact of around minus three million euros on earnings before interest, taxes, depreciation and amortization without hedging.

Analysts expect the weak dollar to affect other DAX companies. JP Morgan, for example, has just withdrawn its buy recommendation for Airbus shares $AIR (-0,23 %) shares, partly because the exchange rate is putting pressure on profit margins. The aircraft manufacturer mainly produces in the eurozone, while the majority of its revenue is generated in dollars.

The real beneficiaries of the weak dollar are based in the USA. For example, the world's largest healthcare group Johnson & Johnson $JNJ (+2,56 %) has just raised its forecast for 2025. The second quarter was stronger than analysts had expected. In international business, however, Group sales grew almost solely due to the positive impact of the dollar.

The current weakness of the dollar as the world's leading currency is not only affecting companies that trade with the USA: All companies, regardless of whether they export to Asia, Oceania, Africa or South America, are affected, as the majority of international payment transactions and trade contracts are still settled in US dollars.

Experts expect the dollar to weaken further.

"In our view, we are only at the beginning of the bear market for the dollar," says Laurent Denize, co-investment manager at Oddo BHF. Many banks are assuming that the 1.20 dollar per euro mark could soon be reached.

There are several reasons for this: the tariff and trade dispute, the associated changeable and unpredictable policy in the US, the high level of new debt and, finally, US President Donald Trump's public criticism of Federal Reserve Chairman Jerome Powell. All of this is undermining confidence in a reliable US policy - and: "All of this is tarnishing the image of the US dollar," says foreign exchange expert Sonja Marten from DZ Bank.

The discussion about a possible de-dollarization has been gaining momentum for months. This refers to the debate about whether the US dollar is losing its nimbus as the world's reserve currency. "For the first time in a long time, we believe this discussion is actually justified," says Marten. In her opinion, investors looking for alternatives to the dollar will inevitably end up in the eurozone.

If this happens, the euro will continue to gain in value as money flows from dollar to euro investments.

The trend towards the euro is likely to be fueled by the fact that the European Central Bank has probably almost reached the end of its cycle of interest rate cuts after eight cuts in the last two years. The financial markets are only pricing in a further small interest rate cut of 0.25 percentage points by the end of next year.

By contrast, market participants in the US are expecting four interest rate cuts totaling one percentage point by the end of 2026, according to data from the financial news service Bloomberg. The interest rate level between the two currency regions is therefore likely to converge.

The result: the previous advantage for investors in the USA of receiving more interest for their investments there would disappear. This would make dollar investments (even) less attractive in future and, in turn, create further potential for the euro - to the chagrin of export-oriented companies from the eurozone with a strong international presence.

Can't find any information on today's pleasing plus. Anyone have any info?

The second.

Unfortunately, chemistry is not going so well at the moment, but I am still convinced in the medium to long term.

I was inspired by a Focus Money article and because many people here are asking.

I won't be investing myself, it's too short-term for me. But there are still some very interesting companies.

The signs of a peace process in Ukraine are solidifying. This is triggering a run on the stock market for shares that could benefit from reconstruction

Regardless of the political interpretation, the stock market has been turning its back on the war for several days now and is betting on the coming peace. Stocks that are likely to benefit from the reconstruction in Ukraine have soared. The UBS Ukraine Reconstruction Index, which comprises 25 of these stocks, has been climbing for days and is at an all-time high. "The effects of a possible ceasefire in Ukraine are still being underestimated on the financial markets," says Bernd Meyer, Chief Investment Strategist and Head of Multi Asset at Berenberg, who is convinced that the rally will continue. Reconstruction requires enormous resources. According to estimates by the World Bank, the costs for this amount to a total of 500 billion dollars - the equivalent of Austria's gross domestic product and more than three times Ukraine's annual economic output before the war. The money is likely to benefit construction companies, suppliers, infrastructure companies and banks in particular. European companies could be the main beneficiaries - especially from neighboring countries such as Poland and Hungary, but also the Czech Republic, Austria and Germany.

With Wärtsilä $WRT1V (+0,62 %) a provider of technologies for the shipping and energy markets, and Konecranes $KCR (+2,4 %) a manufacturer of industrial cranes and drive technology, Finnish companies are also on the list of potential peace beneficiaries - as are Italian companies such as the cement and building materials manufacturer Buzzi $BZU (+2,28 %) The list is long. There is a great need for building materials, steel and cables to restore the destroyed infrastructure and energy supply. There is still no thematic fund or ETF on the beneficiaries of the reconstruction in Ukraine. Investors who want to benefit from this are therefore well advised to combine several securities into a portfolio themselves.

A few days before the Bundestag elections, Wall Street has discovered its special love for Europe and German second-line stocks. The small cap index MDaxwhich is usually overshadowed by the Dax, is suddenly enjoying a level of attention not seen for years. Several major Wall Street addresses have published analyses of the index of medium-sized companies almost simultaneously.

The MDax is considered to be one of the most undervalued indices in the Old World and this is precisely what makes it particularly attractive from Wall Street's perspective. The Bundestag elections are fueling this bet: if Germany manages to turn the economy around afterwards, the MDax could benefit disproportionately.

Around a third of the MDax companies' business is attributable to the domestic market. Accordingly, the local misery has weighed much more heavily on the index. By contrast, the index has not yet priced in the economic policy stimuli that could arise after the election.

Possible beneficiaries are (examples):

Through lower energy costs:

$WCH (+0,96 %) | $LXS (+0,44 %) | $GBF (+0,78 %)

Improved consumer sentiment:

$CTS (+0 %) | $BOSS (+0,01 %) | $SIX2 (+1,41 %)

Suitable funds could be

$EXID (+1,43 %) | $MD4X (+1,41 %)

1) INTRODUCTION

Since 2023 at the latest and the rapid rise of Nvidia $NVDA (-0,56 %) semiconductors and "AI chips" in particular have been the talk of the town. Since then, investors have been chasing after almost every company that has something to do with the production of chips, driving share prices to unimagined heights. However, hardly any investors really know how complex the value chain is within the production of modern chips.

In this article, I will give you an overview of the entire production process and the companies involved. Even if many of you have a vague idea that the production of modern chips is complex, you will certainly be surprised by how complex it really is in reality.

2) BASIC

The starting point for every chip are so-called wafers [1] - i.e. thin wafers, which usually consist of so-called high-purity monocrystalline silicon. In the field of power semiconductors, which primarily comprises chips for applications with higher currents and voltages, silicon carbide (SiC) or galium nitride (GaN) has recently also been used as the base material for the wafers.

In the so-called front end the actual core components of the chips - the so-called dies - are created and applied to the wafers. The dies are rectangular structures that contain the actual functionality of the later chip. The finished dies are then tested for their functionality and electrical properties. Each die that is found to be good is then integrated into the so-called backend where the individual dies are separated on the wafer. This is followed by the so-called packaging. The individual dies from the front end are then electrically contacted and integrated into a protective housing. In the end, this housing with the contacted die is what is usually called the chip chip.

Now that we have a rough overview of the overall process, let's take a closer look at the individual processes involved in producing the dies on the wafer. This is the area in which most highly complex machines are used and which is usually the most sensitive.

3) FROM SAND TO WAFER

Before wafers made of high-purity silicon can even be produced and the actual process for manufacturing dies can begin, the actual wafer must first be manufactured in almost perfect quality. To do this, quartz sand, which consists largely of silicon dioxide, is reduced with carbon at high temperatures. This produces so-called raw siliconwhich, with a purity of around 96%, is not yet anywhere near the quality required for the production of wafers.

In several chemical processes, which are carried out by Wacker Chemie
$WCH (+0,96 %) or Siltronic
$WAF (+0,6 %) are used to turn the "impure" silicon into so-called polycrystalline silicon with a purity of 99.9999999%. For every billion silicon atoms, there is then only one foreign atom in the silicon. However, this pure polycrystalline silicon is still not suitable for the production of wafers, as the crystal structure in the silicon is not uniform enough. In order to create the right crystal structure, the polycrystalline silicon is then melted again and a so-called ingotwhich is made from monocrystalline silicon is produced. A comparison between raw silicon and the ingot can be found in the following image [3]:

This ingot is then sawn into thin slices, which are then the final wafers for semiconductor production. The best-known wafer producers are Shin Etsu
$4063, (-0,29 %)
Siltronic or GlobalWafers
$6488.

4) FROM THE WAFER TO THE DIE

The wafers described in the previous section can now be used to produce dies. The overall process for producing dies basically consists of applying a large number of layers using various chemical, mechanical and physical processes. The overall process (depending on the product) takes approx. 80 different layers on the wafer, requiring almost 1000 different process steps and 3 months
non-stop production are required [4].

A macroscopic analogy is useful here, which I have also taken from [4]. You can compare the overall process for producing dies with baking a large multi-layer cake. This cake has 80 layers and the recipe for baking it consists of 1000 steps. It takes 3 months to make the cake and if even one layer of the cake deviates from the recipe by more than 1%, the whole cake collapses and has to be thrown away.

In the first process steps, the wafer is covered with billions tiny little transistors are created on the wafer, which are then all individually electrically contacted in the following steps. The final steps consist of electrically connecting the transistors to each other, resulting in a complete electrical circuit [4]:

Each individual layer of the approximately 80 layers in the die requires highly specialized processes, which can be roughly summarized as:

• Applying masks: Photolithography, photoresist coating (applying photoresist)
• Apply material: Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), Atomic Layer Deposition
• Remove material: Plasma annealing, Wet annealing, Chemical Mechanical Planarization (CMP)
• Modify material: Ion Implanting, Annealing
• Material cleaning
• Inspecting the layers: Optical, Microscopical, Focused Ion Beam, Defect Inspection

Apply masks

Ultimately, a mask can be thought of as an enlarged copy of the structure of a special layer in the die. These so-called photomasks are then scanned using so-called scanners or steppers "copied" in reduced size onto the wafer. The best-known manufacturer of such lithography systems is ASML
$ASML (+0,68 %). It is currently the only producer of lithography systems that make it possible to produce structures smaller than 10 nanometers on the wafer. In today's powerful and modern chips, such as those found in smartphones, AI chips and processors, the smallest structures are around 3 nanometers in size. Other manufacturers of lithography systems for larger structures (10nm and larger) are Canon Electronics
$7739 or Nikon $7731 (+0 %) .

The photomasks - i.e. the enlarged "copies" of the structures - are produced by companies such as Toppan $7911 (+0,75 %) , Dai Nippon Printing
$7912 (+0,61 %) or Hoya $7741 (+0,6 %) manufactured. Systems for cleaning the photomasks or for applying the photoresist are produced, for example, by Suss Microtec
$SMHN (+2,25 %) for example.

Apply/remove/modify/clean material

As can be seen in the overview above, there are a variety of methods and processes for modifying the material of a particular layer. As a result, there is a lot of different equipment that can handle a process very well with incredible specialization. The best-known and most successful equipment manufacturers include Applied Materials $AMAT (-0,12 %), LAM Research
$LRCX (-0,48 %), Tokyo Electron (TEL)
$8035, (+3,44 %)
Suss Mictrotec, Entegris
$ENTG (+4,24 %) and Axcelis $ACLS (+1,01 %).

The material - for example, highly specialized chemicals - is of course also required for production. Companies such as Linde
$LIN (+0,42 %), Air Liquide
$AI (+0,51 %), Air Products
$APD (+1,01 %) and Nippon Sanso
$4091 (+0,2 %) are major manufacturers of process gases such as nitrogen, hydrogen and argon.

Inspect

As mentioned, every single layer in the manufacturing process of a die must be perfect in order to obtain a functional die at the end. Any small deviation or foreign particles can impair the functionality of the die. As the function of the die can only be checked precisely on the finished die, it is advantageous to inspect the individual layers for defects and deviations during production. Special machines are required for this, which must be able to do different things depending on the layer. Manufacturers of such machines include KLA
$KLAC (-0,7 %) or Onto Innovation
$ONTO (+0,73 %).

The following applies to almost all of the companies mentioned in this section: the companies are highly specialized and have quasi-monopolies on the machines for certain process steps. quasi-monopolies. Suitable equipment therefore usually costs several million dollars. In addition, some of the systems are so complex that they can only be maintained by the manufacturer's own service staff, which ensures recurring service revenue for every machine sold. As a rule, each machine requires several highly specialized engineers to ensure long-term stable operation.

5) FROM THE DIE TO THE FINISHED CHIP

Once the wafer has been processed, the dies on the wafer are checked for functionality. There is highly specialized equipment for this, so-called probers. These probers test each individual chip several times, if necessary, to check the functionality implemented in the design. Manufacturers of such probers include Teradyne $TER (+0,74 %), Keysight Technologies
$KEYS (+2,3 %), Onto Innovation or Tokyo Electron. These probers have to control each individual die, some of which are only a few square millimetres in size, and contact the corresponding much smaller test structures with tiny needles. The testing process is sometimes outsourced to entire companies that offer die testing as a complete package. One example of such providers is Amkor Technology
$AMKR (-3,35 %).

The processed and tested wafer is now sawn to obtain individual dies. The dies that are found to be good are then integrated into a protective housing in the backend. The dies that have not passed the functionality test are either sorted out or (depending on the error pattern) processed as a variant with reduced functionality similar to those with full functionality. After a final functional test in the package, the chip is ready for use.

6) FOUNDRIES, FABLESS & SOFTWARE

Now that we have an overview of the complex process of manufacturing a chip, let's zoom out a little further to understand which companies perform which tasks in the semiconductor industry.

It's funny that not once in the manufacturing process has the name Nvidia $NVDA (-0,56 %) or Apple $AAPL (-1,19 %) has been mentioned? Yet they have the most advanced chips, don't they?

The pure production of the chips is done by other companies - so-called foundries. Companies like Nvidia and even AMD $AMD (-2,18 %) are in fact fablessThis means that they do not have their own production facilities but only supply the chip design and let the foundries manufacture the actual chip according to their design.

The design of a chip is like the blueprint for production - the foundries then take over the recipe creation and the actual production. There is special software for designing chips. Companies known for this software include Cadance Design
$CDNS (+0,59 %) and Synopsys $SNPS (+2,19 %). But also the industrial giant Siemens
$SIE (+2,7 %) now also supplies software for designing integrated circuits. Synopsys also offers other software for data analysis within foundry production.

Speaking of foundries; the best known foundry is probably TSMC
$TSM, (-0,98 %) which is the global market leader in foundries. TSMC designs itself no chips itself and specializes exclusively in the production of the most advanced generations of chips. Another major player that also masters the most advanced structure sizes is Samsung $005930. In contrast to TSMC manufactures Samsung also produces its own designs. Other large foundries are Global Foundries
$GFS, (-2,47 %) which was originally a spin-off from AMD and the Taiwanese company United Micro Electronics
$UMC. (+0,74 %)

The best-known fabless companies - i.e. companies without their own chip production - are Nvidia, Apple, AMD, ARM Holdings
$ARM, (-3,26 %)
Broadcom $AVGO (+0,21 %), MediaTek $2454 and Qualcomm $QCOM. (-0,25 %) In the meantime Alphabet $GOOGL, (+0,84 %)
Microsoft $MSFT, (+2,41 %)
Amazon $AMZN (+3,14 %) and Meta $META (-0,3 %) have designed their own chips for certain functionalities and then have them manufactured in foundries.

In addition to foundries and fabless companies, there are of course also hybrid models, i.e. companies that take on both production and design. The best-known examples of this are, of course, companies such as Intel
$INTC (-2,46 %) and Samsung. There is also a whole range of so-called Integrated Device Manufacturer (IDM)which for the most part only manufacture their own designed chips and do not accept customer orders for production. Well-known companies such as Texas Instruments
$TXN, (-1,53 %)
SK Hynix
$000660,
STMicroelectronics
$STMPA, (-1,07 %)
NXP Semiconductors
$NXPI, (-1,46 %)
Infineon $IFX (+0,79 %) and Renesas $6723 (-0,85 %) are among the IDMs.

FINAL WORD

The aim of this article was to provide an overview of the complexity of the semiconductor industry. I do not, of course no claim to be complete, as there are of course many other companies that are part of this value chain. As Getquin thrives on active exchange, I'll give you some food for thought to discuss in the comments below the article:

• feel free to link any other companies in the comments if you think I've forgotten any relevant ones
• what was the most surprising new information for you from the article?
• which companies from the article have you never heard of?
• before reading the article, did you know approximately how a modern chip is produced and what steps are necessary for this?

In general, I can recommend the 20-minute YouTube video at [4] to any interested reader. It provides an excellent animated overview of the manufacturing process of modern chips.

Stay tuned,

Yours RealMichaelScott
