Runxi Microelectronics Chongqing Co., Ltd.
Runxi operates the twelve-inch power-semiconductor wafer line, focusing on process uniformity, thin-wafer handling and production ramp on larger wafers. It shares device knowledge with the eight-inch line but has different tools, windows and ramp risks, so capacities cannot be merged casually.
