US Government Says ASML's Top EUV Lithography Tool May Already Be in China
Tags Infrastructure · China · Export Controls · Chips
US Commerce Secretary Howard Lutnick stated publicly that ASML's most advanced extreme ultraviolet (EUV) lithography machine — the TWINSCAN NXE:3800E, used to fabricate chips at 3nm and below — may already be operating in China. ASML CEO Christophe Fouquet denied the claim, saying no such tool has been shipped to a Chinese customer. ASML's EUV systems are subject to Dutch export controls aligned with US policy, and a shipment would require a license ASML does not currently hold for Chinese destinations. The allegation, if true, would represent a significant escalation of China's domestic chipmaking capability; industry analysts note the commercial logic cuts against ASML risking its export license.
Technical significance
If an EUV tool is confirmed in China, it would mean China can fabricate advanced logic chips at scale without relying on external foundries — a strategic capability with implications for AI hardware autonomy and military electronics. ASML's denial notwithstanding, the US government's public allegation suggests intelligence community confidence in the claim, which would trigger additional export control tightening and potentially broader trade restrictions.
