SK Siltron to bring new 300mm wafer capacity online as AI demand lifts shipments

SK Siltron's planned launch of a new silicon wafer manufacturing facility in South Korea next month reflects the growing demand for wafers driven by AI data center investments. While AI technology adv... Read original →

SK Siltron’s new 300mm wafer line is a direct response to AI data center buildouts, not speculative capacity. Technically, it pressures equipment vendors to refine crystal growth for EUV compatibility and edge uniformity, while forcing foundries to relax defect density specs. Geopolitically, South Korea reduces reliance on Shin-Etsu, yet U.S.-led export controls on lithography tools could delay yield ramp. Competitors like GlobalWafers and SUMCO will likely lock long-term HBM-grade wafer deals or slash prices, igniting a margin war. Over the next 18 months, despite surging AI-driven demand, the flood of 300mm capacity added since 2023 will cap gross margins below 15%, compelling players to adopt smart manufacturing and silicon recycling—shifting the wafer industry from resource leverage to operational excellence.
