Germany's Hidden Champions Stake Their Claim in the Semiconductor Supply Chain: The Industrial Logic Behind EUV Core Technology

Germany's Hidden Champions Stake Out the Semiconductor Supply Chain: The Industrial Logic of EUV Core Technology

Competition in advanced process nodes is often reduced to an investment race among wafer fabs. But as Samsung, TSMC, and Intel fight over yields in fabs that each cost around ten billion dollars, a more hidden constraint comes from several quiet towns in southwestern Germany. This is where the "throat" of the EUV lithography system lies.

In mid-July, TRUMPF, ZEISS, and Merck opened their semiconductor cleanrooms and R&D facilities to Asian media. These moves look routine, yet they clearly reveal a simple fact: every one of the world's most advanced chips depends on key components made by German companies. TRUMPF's laser modules bombard tin droplets at 30KW power in ASML's EUV machines to generate ultraviolet light of extremely short wavelength; ZEISS's mirror systems ensure that this light can be focused with atomic-level precision; Merck's specialty gases and chemicals run through every stage of coating, etching, and cleaning. The three companies' technologies interlock, forming a supply chain barrier that is almost impossible to bypass.

Why Germany Holds This Barrier

Extending the timeline reveals that these three companies are not "native" semiconductor players. Merck traces its roots to a 17th-century pharmacy and chemicals business, ZEISS started with microscopes, and TRUMPF was known for machine tools. The technical path they share is transferring the precision capabilities honed in traditional industries into the entirely new application scenario of semiconductors. When ASML needed a laser system capable of delivering extreme ultraviolet light, TRUMPF's high-power laser technology, accumulated through metal processing, was directly converted; when the optical path demanded extremely smooth mirror surfaces, ZEISS's century of optical expertise came into play. This ability to migrate across domains is precisely the core hidden asset of the German manufacturing system.

Another pillar supporting the hidden champions is Germany's dual vocational training system. TRUMPF trains about 150 mechanical and electrical apprentices at its headquarters each year; ZEISS continuously cultivates precision optics talent; Merck builds joint research projects with TU Darmstadt. By embedding themselves deeply in talent development, companies ensure that their technical know-how is passed down across generations. This explains why these German companies, despite their modest size, can maintain global monopolies in extremely niche fields.

What This Means for the German Industrial System Germany is experiencing the birth pangs of its automotive industry transformation, but the semiconductor materials and equipment business appears to have become an unexpected stabilizer. The expansion plans publicly announced by three companies—ZEISS receiving €222 million in EU support to expand its optical systems production lines, and Merck completing the €3 billion investment launched in 2021—indicate that this segment has entered a period of cyclical prosperity. For German manufacturing, this has a dual meaning: on the one hand, it provides a new export growth pole and profit source; on the other hand, it deepens German industry's dependence on Asian manufacturing bases. About 80% of semiconductor manufacturing is concentrated in Asia, and German companies sit upstream—a mismatch that leaves the German economy exposed to indirect risks when geopolitical tensions in Asia escalate.

Under the EU Chips Act, the German government is providing €5 billion in subsidies to the joint-venture wafer fab in Dresden involving TSMC, Bosch, Infineon, and NXP, with the goal of bringing part of the manufacturing process back home. But a deeper strategic question is: Germany's true industrial lifeline does not lie in those wafer fabs that need subsidies to survive, but in the upstream nodes where Merck, ZEISS, and TRUMPF operate. If Germany positions itself according to the old logic of "manufacturing capacity," it is likely to fall into high-cost competition with East Asia and the United States; if it instead strengthens its role as a "key equipment and materials supply center," it can gain more durable bargaining power in the restructuring of global supply chains.

Variables in the European and Global Competitive Landscape

The positioning of Germany's hidden champions has in fact changed the underlying narrative of Europe's semiconductor strategy. Europe does not have a first-class wafer foundry, yet it holds the indispensable "key" to manufacturing advanced chips. Driven by AI, the global semiconductor market is expected to surpass $1 trillion this year and double by 2030, giving Europe a path to profit from the chip boom without relying on large-scale manufacturing.

At the same time, geopolitics is reshaping the semiconductor supply chain. US export controls on China and the wave of subsidy policies introduced by various countries have driven global wafer fab construction toward the United States and Asia. German companies must simultaneously serve multiple regional markets and comply with different export rules. Frank Rohrmüller, CEO of ZEISS SMT, explicitly stated that factory expansions around the world are the source of their orders. But this also makes "technological neutrality" increasingly difficult: once key technologies are politicized, German companies may be forced to choose between their largest market and the security alliance.

Direction for the Next Three to Ten Years

Germany's bottleneck position in the semiconductor supply chain will not be shaken in the short term. Strict customer qualification, decades of process accumulation, and organizational knowledge mean the cycle for replacing suppliers is extremely long. In the next five years, as Intel, TSMC, and Samsung successively bring their plants in Arizona, Dresden, and Kumamoto, Japan, online, demand for German equipment and materials will only increase.But longer-term changes may occur at the technology roadmap level. High-NA EUV, next-generation lithography, and novel interconnect materials will all test whether German companies can sustain their technological lead. At the same time, China, South Korea, and Japan are all increasing their independent R&D investment in semiconductor equipment and materials, trying to break through the "hidden champion" barriers. German companies must continue to maintain the technology gap through high R&D spending while remaining alert to knowledge diffusion driven by talent mobility.

An even more important trend is that German industry may make "irreplaceability" the core goal of its national manufacturing strategy. Rather than competing for share in mature process nodes, it is better to make itself "indispensable" at every critical juncture. This is precisely the continuation of Germany's traditional industrial philosophy in the digital age: pursuing not a grand narrative of scale, but a position that cannot be bypassed.

As the world debates who will win the chip war, Germany's hidden champions offer a different answer — whoever controls the critical nodes controls the pace of the entire chain. For German industry, competitiveness over the next decade may not depend on how many chips it can produce, but on whether it can continue to make every advanced chip pass through German technology nodes.
