Samsung to exit 8-inch foundry business by 2030, report says

Samsung's 2030 exit from 8-inch foundry is a structural realignment of the global analog and power-semiconductor manufacturing map, not routine capacity rationalization. The technical ripple is precise: 8-inch wafers carry automotive MCUs, PMICs, MEMS, and SiC power devices—categories where 12-inch is economically irrational. Samsung's withdrawal strips Korean fabless designers of their sole domestic manufacturing anchor. Upstream, LAM and AMAT will see 8-inch incremental orders accelerate their decline, while process IP concentrates further among fewer foundries. The supply-chain exposure is sharper than it appears. With rivals' capacity near saturation, Korean design houses face a repricing event—8-inch wafer pricing will likely climb 15-25% within 18 months. The deeper risk: if Korean firms pivot to UMC or PSMC in Taiwan, China, or Hua Hong in mainland China, any single update to export-control lists can sever that fallback path overnight. Strategically, UMC and GlobalFoundries are the direct beneficiaries. The 2021 analog-chip shortage proved foundry bargaining power compounds exponentially during scarcity. Samsung's departure hands rivals a competition-free window—whether they exploit pricing power or expand capacity will define the next cycle. Over the next 12-24 months, expect Seoul to mirror its memory-chip subsidy playbook, deploying targeted industrial funds for 8-inch or fabless support. Global 8-inch capacity will contract roughly 20% by 2030. This is not a cyclical dip—it is an industry endgame.
