Shanghai-based Yuanjiwei has launched an 8-inch pilot production line for 2D semiconductors and claims it will produce 5-nanometre-equivalent chips without EUV lithography by 2029, marking a shift from laboratory research to manufacturing validation amid US export controls on advanced chipmaking equipment.
This Wire brief sits within Fusion42's coverage of Semiconductors.
◆ ◆ The Wire takeaway
If you make materials, tools, or equipment for chip manufacturing, China just moved 2D semiconductors from theory to production scale - and they're doing it without the EUV machines they can't buy from you. Your customers in Asia will soon have a domestic alternative that skips your most expensive step.
