onsemi’s divestiture of two Arizona fabs isn’t merely cost-cutting—it’s a strategic pivot toward 300mm wafers and intelligent power solutions. This accelerates offloading legacy 200mm capacity to third-party foundries, invigorating the secondary equipment market and benefiting IDMs in Taiwan, China and mainland China. However, CFIUS scrutiny looms if buyers have Chinese ties, given CHIPS Act restrictions on advanced-capacity investments in China. Competitors like Infineon and STMicroelectronics may reassess aging assets amid softening automotive MCU demand. Within 18 months, a ‘light-asset IDM’ model—where >60% of manufacturing is outsourced—will dominate, compelling equipment vendors to develop modular, relocatable fab solutions. This marks not just financial discipline, but a fundamental rewiring of supply chain resilience.
