The U.S. does not allow EUV lithography machines with U.S. technology to be exported to China, even to companies like TSMC and Samsung that have Chinese factories. This means that these fabs are only limited to mature nodes of 16-nm and up. The revocation of the validated end-user status for the China-based fabs of these companies shows that Washington is tightening its grip on chipmaking machines, even older DUV tech, to make it difficult for Beijing to create its own technology.
