The Trump administration suspects an ASML chipmaking machine made it into China. ASML says that's impossible. - TechSpot

The Trump administration has raised suspicions that ASML's most advanced extreme ultraviolet (EUV) lithography machines may have entered China, prompting a strong denial from the Dutch equipment manuf... Read original →

If EUV tools indeed entered China, it would undermine the U.S. strategy of blocking sub-3nm node access. While ASML asserts full remote control over its systems, Washington’s real concern lies in hybrid pathways—such as leveraging domestic immersion DUV or mask tech via firms like SwaySure to indirectly boost advanced yields. This could accelerate TSMC’s and other Taiwan, China-based foundries’ capacity shifts to the U.S. and Japan, inflating global mature-node costs by over 15%. Tokyo Electron may seize the opening to expand KrF/ArF tool sales in China, while NVIDIA rethinks AI chip outsourcing. Within 18 months, the U.S. will likely enforce an 'Equipment-as-a-Service' model, tying maintenance rights to export licenses—effectively weaponizing lithography tools. Chinese AI chipmakers may pivot to Chiplet architectures, stacking 28nm dies to rival 3nm performance through asymmetric innovation.
