China’s YMTC expansion
China’s memory‑chip champion Yangtze Memory Technologies plans two new fabs that would more than double its NAND production capacity as it pushes ahead amid heightened U.S.–China trade tensions. (reuters.com) YMTC is raising memory density using existing deep‑ultraviolet lithography while Beijing has poured roughly $142 billion into chipmaking subsidies over the past decade — a mix of technical workaround and heavy state financing. ( ) At the same time U.S. export‑control enforcement is being strained by licensing‑office staff losses that have slowed approvals, and lawmakers are proposing to extend restrictions to DUV equipment via the MATCH Act.

China’s top NAND flash maker is planning two more factories, a buildout that would more than double its output if all three new lines come online. (usnews.com) Yangtze Memory Technologies, or YMTC, already runs two plants with combined capacity of 200,000 wafers a month, and sources told Reuters each of the three new plants is designed for 100,000 wafers a month at full scale. (usnews.com) The third plant, in Wuhan, is expected to start operating in late 2026 and reach 50,000 wafers a month by 2027. Reuters reported the building is finished and equipment is being installed. (usnews.com) NAND flash is the storage chip inside phones, laptops, and solid-state drives. YMTC is expanding that business while the United States keeps tightening semiconductor export controls aimed at slowing China’s access to advanced tools. (usnews.com; federalregister.gov) YMTC has been on the United States Entity List since December 2022, and Reuters reported it has since deepened work with local toolmakers including Advanced Micro-Fabrication Equipment. More than half of the equipment going into the third fab is coming from domestic suppliers, including tools used to stack chip layers vertically. (federalregister.gov; usnews.com) That local push sits inside a much larger state effort. China spent about $142 billion on chipmaking subsidies from 2014 through 2023, versus about $39 billion in the United States over the same period, according to figures cited by Tom’s Hardware. (msn.com) Washington’s enforcement system is also under strain. Bloomberg reported in April that the Bureau of Industry and Security had lost nearly 20% of its rulemaking and licensing staff over the prior year, while a 2025 Government Accountability Office report said the bureau lacked a long-term workforce plan. (bloomberg.com; gao.gov) Lawmakers are meanwhile pushing to widen the choke points. The proposed MATCH Act would extend restrictions beyond extreme ultraviolet machines to some deep ultraviolet lithography tools, the older equipment still used across much of the chip industry. (nbcnews.com; finance.yahoo.com) YMTC was founded in Wuhan in 2016 with backing from local government and state chip funds, and analysts cited by Reuters said its latest Xtacking 4.0 design is comparable to products from Samsung Electronics. Reuters also cited a UBS estimate that YMTC held 11.8% of the global NAND flash market last year. (finance.yahoo.com) The next test is whether YMTC can turn planned capacity into steady output before export controls tighten again. Reuters reported the company did not respond to a request for comment on the expansion plans. (usnews.com)
