The US says ASML’s top chip tool may be in China. ASML says it isn’t

Summary

The U.S. Commerce Department, led by Secretary Howard Lutnick, has expressed concerns to ASML executives that one of its extreme ultraviolet (EUV) lithography machines, critical for advanced semiconductor patterns, may have reached China, violating export controls in place since the first Trump administration. ASML, Europe's most valuable public company with a market capitalization near \$700 billion, denies this claim, stating it tracks all machines and has internal firewalls preventing EUV technology access for China-based staff. The company's CEO, Christophe Fouquet, emphasized the complexity of EUV development and the commercial risk of jeopardizing its permitted deep ultraviolet (DUV) sales to China, which are expected to constitute 20% of its 2026 revenue. This scrutiny comes as the Commerce Department invested up to \$150 million in xLight, a startup developing next-gen light-source technology, and Peter Thiel backed Substrate, another EUV-rival startup. A bipartisan bill also proposes banning all ASML DUV shipments to China.

Key takeaway

For Directors of AI/ML and investors monitoring global supply chains, this situation highlights the extreme fragility of advanced chip access. You should assess your reliance on specific lithography technologies and the potential impact of escalating export controls, including the proposed DUV ban, on your long-term hardware procurement and strategic partnerships. Geopolitical tensions directly influence the availability and cost of foundational AI infrastructure.

Key insights

U.S. export controls on advanced chip technology face scrutiny amid allegations of an ASML EUV machine reaching China.

Principles

• Advanced lithography tools are critical chokepoints in global AI development.
• Export control regimes are complex and difficult to enforce.
• Commercial interests can align with or oppose national security goals.

Method

ASML tracks all shipped machines and implements internal firewalls to restrict EUV technology access for specific regions.

In practice

• Implement robust internal tracking for sensitive technology exports.
• Establish strict access controls for proprietary technical data.
• Evaluate commercial risks of non-compliance with export regulations.
