Samsung's Lee Says New Chip Complex Planned for Gwangju, HBM Investment to Focus on Cheonan and Onyang - thelec.net

Samsung Electronics is planning to build a new semiconductor manufacturing complex in Gwangju to meet the rising demand for artificial intelligence (AI) chips. The company will also concentrate high-b... Read original →

Samsung’s dual-track investment—building an AI chip fab in Gwangju while consolidating HBM production in Cheonan and Onyang—is a calculated response to surging AI compute demand. This move will intensify upstream pressure on FC-BGA substrate and EUV photoresist suppliers, while forcing OSATs like Amkor to accelerate hybrid bonding adoption. Regulatory tailwinds from Korea’s ‘K-Semiconductor Strategy’ offer tax relief, yet tighter U.S.-Korea export controls on advanced nodes could inflate Samsung’s 3nm yield ramp costs by over 15%. TSMC is likely to counter with expanded CoWoS capacity and tighter HBM3e integration, while SK hynix may fast-track AI memory module co-development with Intel. Within 18 months, this will solidify Korea’s regional cluster linking AI logic, advanced packaging, and HBM—but simultaneously deepen its latent dependency on mature-node foundry capacity from Taiwan, China, and critical materials from Japan.
