Chinese semiconductor production surge impacts Shin-Etsu Chemical and SUMCO

Reports indicate a significant surge in production capacity within China, which is directly impacting major silicon wafer suppliers Shin-Etsu Chemical and SUMCO.

Context

China’s aggressive expansion in mature-node chip manufacturing is creating a significant demand surge for silicon wafers, directly impacting Japanese industry leaders Shin-Etsu Chemical and SUMCO. As Beijing pushes for self-sufficiency, China’s integrated circuit output rose by over 11% in 2024, with the country projected to control 28% of global legacy chip capacity by the end of 2025. This volume-driven growth provides a critical buffer for wafer suppliers against sluggishness in other high-tech consumer sectors. Despite the volume boom, investors are tracking China’s rapid localization of its material supply chain. Domestic Chinese wafer production has hit 1 million units monthly, leading to some lost market share for SUMCO in legacy memory segments. However, the Japanese giants still hold a combined 56% of the global market and over 90% of the high-end 300mm wafer segment. This technical moat remains vital as China's "explosive" production still requires high-purity materials that domestic suppliers cannot yet replicate at scale.
