SMIC

Semiconductor Manufacturing International Corporation (SMIC), headquartered in Shanghai, is China's largest pure-play foundry, producing integrated circuits on customer designs from mature nodes (350nm) to 5nm-class processes using deep ultraviolet (DUV) multi-patterning due to U.S. export restrictions blocking extreme ultraviolet (EUV) access. It serves fabless firms like Qualcomm and Huawei with logic, RF, and power devices, ranking as Asia's second-largest foundry by capacity after TSMC. Key differentiators include its scale, reliance on DUV techniques for sub-7nm scaling, and emphasis on domestic Chinese demand to counter geopolitical constraints.
