蔡司 CEO는 중국이 EUV 리소그래피 기술에서 여전히 15년 뒤처져 있으며, 이는 반도체 제조 격차를 확대하고 있다고 밝혔다.

The gap in extreme ultraviolet (EUV) lithography between China and the West could shrink rapidly under current export controls. Carl Zeiss SMT, the critical optics supplier to ASML, sits at the center of this geopolitical technology race. Understanding the semiconductor industry’s most significant supply-chain commentary provides crucial insight into chip production dynamics heading into 2026.

**Why Is China’s EUV Technology Gap Measured in Years, Not Months?**

The 15-year estimate derives from the fundamental physics of EUV lithography. Carl Zeiss SMT manufactures the mirrors and optical systems that ASML requires for its most advanced machines. These components demand atomic-level precision; a single EUV mirror can cost more than a factory in certain regions. While China’s domestic chip toolmakers have advanced older deep ultraviolet (DUV) technology, EUV requires a synchronized ecosystem of lasers, vacuum chambers, and optics that no entity outside the ASML supply chain has yet assembled. The gap is substantial, but the trajectory matters more than the starting point.

**How Could Sanctions Actually Accelerate China’s Chip Progress?**

Export controls generate scarcity, which in turn drives domestic investment. In response to U.S. restrictions, Chinese semiconductor firms are allocating significant resources toward alternative lithography approaches, including multi-beam and nanoimprint technologies. Paradoxically, sanctions compel China to bypass incremental development. Rather than perfecting DUV, Chinese researchers are advancing directly to next-generation methods that may circumvent EUV entirely. Should any of these alternative pathways achieve commercial viability, the projected 15-year gap could narrow in under five years.

**What Role Does Carl Zeiss Play in the EUV Supply Chain?**

Carl Zeiss SMT does not manufacture chips; it serves as the optical backbone of the entire EUV ecosystem. Every ASML machine ships with Zeiss optics, positioning the German company as a critical chokepoint for advanced semiconductor manufacturing. The CEO’s remarks were made during a discussion on export policy, a timing that carries strategic weight as governments weigh whether to tighten or relax restrictions on dual-use technologies. Although China remains reliant on Western suppliers for the most advanced components, that dependency is not permanent.

**Is 15 Years a Comfortable Lead or a Dangerous Assumption?**

Fifteen years may appear to be a comfortable buffer, but semiconductor history demonstrates that breakthroughs rarely follow linear timelines. The transition from 193nm to 13.5nm wavelengths required two decades of sustained, multinational effort. The central question is whether China can compress that timeline through unprecedented investment scale. Reports indicate the country is dedicating more capital to chip self-sufficiency than any nation in history. Western policymakers would commit a strategic error by treating the 15-year estimate as a fixed guarantee.

**What Should Industry Leaders Watch For in the Coming Year?**

Industry leaders should closely monitor China’s domestic EUV prototypes and its progress on alternative patterning technologies. Any advancement in extreme ultraviolet source development would signal a structural shift. Equally important are changes in export enforcement; the recent trend toward stricter controls on advanced chipmaking equipment may inadvertently accelerate China’s drive for self-reliance. The semiconductor industry’s next decade will ultimately be defined by the speed at which China closes this technological gap.

**Conclusion: The Gap Is Real, But Speed Matters**

The EUV gap will close; the only variable is whether it occurs in 15 years or five. Stakeholders must track China’s investments in alternative lithography with close attention.
