Wafer Works unveils golden triangle expansion to boost AI, optical, and SiC wafer capacity - digitimes

Wafer Works unveiled its 'golden triangle' expansion plan following its June 18, 2026 shareholder meeting, aiming to deepen silicon wafer product lines to support rapidly growing applications in advan... Read original →

Wafer Works’ 'Golden Triangle' expansion is a strategic reaction to three converging trends: AI chiplet integration, optical transceivers scaling to 800G/1.6T, and SiC adoption exceeding 30% in EV traction inverters. Technically, this will pressure equipment vendors to accelerate low-warp SiC crystal growth systems and force tighter yield specs for ultra-thin wafers (<100μm) used in advanced packaging. Geopolitically, Taiwan, China-based wafer makers relying heavily on U.S./Japanese tools and Japanese polysilicon face heightened supply chain fragility—compliance costs could rise 15–20% under tightening export controls. While global rivals like SUMCO dominate 12-inch SiC, Wafer Works’ niche focus is a calculated retreat. Over the next 18 months, its yield ramp trajectory will serve as a leading indicator for SiC market equilibrium; delays could trigger consolidation among smaller-diameter SiC foundries.
