The 300 mm category accounted for 67.5% of the China semiconductor device market share in 2024, underscoring its status as the production workhorse for logic, memory, and power devices.^{[2]WaferPro, “200 mm Wafer vs 300 mm Wafer,” waferpro.com} Moving to the larger substrate more than doubled usable die area relative to 200 mm wafers and enabled per-die cost reductions of roughly 40% at SMIC’s Shanghai fab, solidifying the node’s margin advantage. These efficiencies encouraged domestic foundries to lock in multi-year take-or-pay agreements with consumer-electronics and cloud-service customers, helping stabilize fab utilization at mature nodes. The resulting scale effects deepened local tooling ecosystems and kept the China semiconductor device market on its forecast trajectory despite external supply shocks.

200 mm lines remained strategically important for specialty analog, sensor, and MEMS devices, yet persistent global shortages kept their capacity fully booked and extended lead times for automotive customers. Pilot projects exploring substrates above 300 mm—including 450 mm initiatives at national research institutes—are projected to grow at an 11.1% CAGR between 2025-2030, a rate that exceeds the broader China semiconductor device market size over the same horizon. Mass adoption of these larger wafers will depend on synchronized equipment roadmaps and the capital intensity tolerable to foundries, but early tooling trials suggest potential yield and throughput gains sizable enough to justify phased investments. Together, the mixed wafer-size strategy provides flexibility to match device requirements with cost structures while cushioning the supply chain against future volatility.
