China pushes for 70% homegrown silicon wafer use as domestic firm ramps up 12-inch production

China is accelerating efforts to localize its semiconductor supply chain, aiming for 70% domestic silicon wafer usage by 2024. This move reflects the country's growing urgency to reduce reliance on fo... Read original →

China’s push for 70% domestic 300mm wafer adoption isn’t just about materials—it’s a strategic lever to rebuild its advanced-node ecosystem. Technically, unless firms like Eswin or NSIG master EUV-grade epitaxial wafers with sub-ppb impurity control, SMIC’s 7nm ambitions remain bottlenecked upstream. Compliance-wise, U.S. export controls now extend to wafer metrology and validation tools, inflating inventory costs for Chinese fabs due to prolonged qualification cycles. In response, TSMC and Samsung will likely accelerate captive wafer supply chains in the U.S., Japan, and Korea, boxing out Chinese players from global markets. Over the next 12–24 months, the real tail risk lies in AI chip designers like Huawei being forced into architectural compromises—sacrificing performance for supply chain sovereignty—thereby redrawing the global HPC value chain.
