ASML’s denial of EUV shipments to China underscores its strict adherence to U.S.-Dutch export controls. Technically, Chinese foundries are locked out of sub-3nm scaling, forcing costly multi-patterning DUV workarounds that inflate defect rates and boost demand for advanced packaging. Compliance risk now extends beyond sales to after-sales support—non-EUV tools could face service cutoffs under U.S. ‘technology traceability’ pressure. Competitors like Tokyo Electron and Nikon can’t replace EUV but are aggressively capturing mature-node equipment share. Meanwhile, NVIDIA faces downstream volatility as Chinese clients struggle with constrained advanced capacity. Over the next 18 months, the U.S. will likely push a ‘friend-shoring’ coalition to localize EUV maintenance and optics servicing in the U.S., Japan, and South Korea, further decoupling China from the high-end supply chain. ASML’s monopoly is morphing from a technical moat into a geopolitical liability.
