Samsung launches mega-project to turn Asan's Onyang campus into HBM packaging hub

Samsung Electronics has begun construction on an advanced HBM packaging plant in Onyang, South Korea, with a 4.6 trillion won investment. The project, aimed at meeting AI server memory demand, will add five fab lines and expand the site's area. The operational start date has been moved up to June 2028, one year ahead of schedule, due to anticipated supply shortages until 2028. Samsung plans to use this as a model for future regional investments.

Jensen Huang’s exit clouds future Nvidia demand for Korean chipmakers

Nvidia's co-founder Jensen Huang resigned, raising concerns about future demand for Korean chipmakers SK hynix and Samsung Electronics. Both companies rely heavily on Nvidia for HBM chip sales, with SK hynix reporting 13.35% of its revenue from a single customer (likely Nvidia). Long-term supply agreements are expected to remain intact, but future demand is uncertain. Analysts suggest AMD, Broadcom, and Marvell could benefit if U.S. export controls impact Nvidia.
