From FPGA to AI: Fudan Microelectronics confronts US FN4 blacklist head-on
Shanghai Fudan Microelectronics Group (FMSH), one of China’s major IC design companies, has been placed on the US Commerce Department’s Entity List with the strict Footnote 4 (FN4) designation. The label requires licenses for all US export-controlled technologies supplied to FMSH, with approvals almost certain to be denied. The FN4 status effectively blocks the company’s access to critical chip design tools and manufacturing services, cutting off its development pipeline.
