GlobalWafers prepares inventory buffer as geopolitical factors push up gallium prices

GlobalWafers’ push into 12-inch SiC and GaN isn’t just about thermal or packaging demands—it’s a geopolitical hedge against tightening Chinese gallium export controls. Technically, this forces equipment vendors to retrofit for larger-diameter compound wafers and extends qualification cycles for power device makers. Compliance-wise, China’s gallium licensing regime has already inflated input costs and delivery risks, compelling strategic stockpiling that erodes margins. Competitively, Shin-Etsu and SUMCO will likely avoid GaN expansion, sticking to silicon for cash stability—giving GlobalWafers a rare window in wide-bandgap semiconductors. Over the next 18 months, supply security will trump performance, accelerating regional material alliances. Expect Taiwanese and Japanese wafer firms to deepen ties with U.S. and European IDMs, forging a de facto China-excluded supply loop.
