U.S. Commerce Secretary Raises Concerns Over Alleged ASML EUV Machine in China

According to Bloomberg, U.S. Commerce Secretary Howard Lutnick has expressed concerns that an extreme ultraviolet (EUV) lithography machine from Dutch chipmaker ASML may have entered China, violating export controls imposed by the Trump administration. The claim, reported by senior administration officials, alleges that ASML shipped EUV-related components and transport equipment to China, though no public evidence has been provided. ASML has denied the allegations, stating no EUV systems exist in China.

Why ASML’s Role in Semiconductor Manufacturing Matters

ASML, a Dutch company, is the sole manufacturer of EUV lithography tools, which are essential for producing the most advanced semiconductors. These machines, developed over two decades, enable the creation of cutting-edge processors used by tech giants like Nvidia and Apple. TSMC, the world’s largest chipmaker, relies on ASML’s tools to fabricate its most advanced chips. The company’s market capitalization exceeds $700 billion, making it Europe’s most valuable public firm.

What Are the Implications of an Alleged Export Violation?

If an EUV machine were in China, it would represent a significant breach of U.S. export controls designed to limit Beijing’s access to advanced AI and military technologies. The U.S. has restricted ASML from selling EUV systems to China since 2018, fearing their use in dual-use applications. A violation could undermine these efforts and accelerate China’s semiconductor capabilities. However, the Commerce Department has not disclosed evidence to corroborate the claims.

ASML’s Response and Internal Safeguards

ASML CEO Christophe Fouquet stated the company tracks all shipped machines, asserting none are in China. He emphasized internal safeguards, including restricted access to EUV technology, with Chinese staff excluded from sensitive areas. Fouquet argued that reverse-engineering EUV systems is impossible without prior access, a claim supported by the company’s 20-year development timeline for EUV light sources.

How Does the U.S. Government’s Investment in Startups Factor In?

The Commerce Department has allocated $150 million in taxpayer funds to xLight, a startup developing alternative lithography technology. While xLight’s CEO described the company as a potential partner to ASML, not a rival, the investment raises questions about the agency’s dual role in both regulating ASML and supporting competitors. ASML has not publicly addressed the funding, but Fouquet dismissed the need for external technology to maintain its dominance.

What’s Next for ASML and U.S.-China Tech Tensions?

A bipartisan bill in Congress seeks to ban ASML’s less advanced deep ultraviolet (DUV) tools from reaching China, targeting a fifth of the company’s 2026 revenue. The Trump administration has not taken a formal stance on the bill, which cleared a key committee in April. Meanwhile, startups like Substrate, backed by Peter Thiel, aim to challenge ASML’s EUV monopoly, though their progress remains uncertain.

Why This Issue Matters for Global AI Development

ASML’s EUV machines are critical to the global AI industry, enabling the production of high-performance chips that power everything from data centers to autonomous vehicles. Any disruption to ASML’s supply chain or export controls could slow advancements in AI and semiconductor technology. The outcome of the U.S. government’s investigation and the bipartisan bill will shape the future of tech competition between the U.S. and China.
