CR Micro Chongqing (Runxi 12-inch Power Line) · 润西微电子（重庆）有限公司
CR Microelectronics Ltd. (STAR: 688396) | Fab
Reported as China’s first domestic automotive-grade 12-inch power-semiconductor fab, from China Resources’ CR Micro — the country’s largest IDM power-semi maker (MOSFET #1 domestically). Hit its 30,000 wafers/month output target in August 2025, roughly 18 months ahead of plan.
Chinese name: 润西微电子（重庆）有限公司 (Rùn Xī Wēidiànzǐ (Chóngqìng))
What does this facility make?
12-inch power wafers: automotive/industrial MOSFETs and IGBTs feeding CR Micro’s module business and EV/PV/storage customers.
Why does it matter?
Evidence that China’s power-semi migration to 12-inch wafers (the global industry’s current cost frontier) is happening at scale and ahead of schedule; July 2026 reporting had CR Micro raising prices across categories ~15% amid 9-month order books — the 2026 power-semi shortage cycle in one company.
