Commentary: fire at Episil threatens tight epitaxial wafer supply

A fire broke out at the Innovation Plant of semiconductor epitaxial wafer maker Episil on October 28. The extent of equipment damage, the scope of production stoppages, and the recovery timeline remain under clarification. With certain products from Episil already experiencing tight supply, largely driven by wafer manufacturing customers lacking internal adjustable capacity, any damage to existing mass-production equipment risks widening the current supply gap.
