US trade officials question ASML over alleged EUV shipments to China - mezha.net

U.S. trade officials have launched an inquiry into ASML, a Dutch lithography equipment manufacturer, over allegations that EUV systems may have been shipped to China. This issue has raised significant... Read original →

If ASML is found to have illicitly shipped EUV tools to China, the ripple effect would cripple advanced node development across Chinese foundries, forcing reliance on inefficient DUV multi-patterning and delaying AI chip scaling. Even without proven violations, U.S. extraterritorial enforcement compels ASML to embed real-time remote disablement and geofencing—raising global support costs. While Nikon and Canon can't replace EUV soon, U.S.-backed startups like xLight and Substrate signal a deliberate strategy to build alternative lithography pathways. Within 18 months, Washington will likely push allies toward a joint semiconductor equipment export review framework, tightening re-export controls on Taiwan, China and South Korean fabs and accelerating the bifurcation of the global chip supply chain into competing blocs.
