SK hynix orders new equipment worth 44.2 bln won for next-gen HBM4 - The Korea Herald

SK hynix has ordered new high-bandwidth memory (HBM) production equipment worth 44.2 billion won (US$28.7 million) from Hanmi Semiconductor, signaling a strategic move to expand HBM4 production for NV... Read original →

SK hynix’s 44.2 billion KRW investment in Hanmi’s TC Bonder 4.5 isn’t just capacity scaling—it’s a strategic lock on the HBM4 node. This thermo-compression bonding tech dictates 3D stacking yield and bandwidth ceilings, forcing co-evolution in EDA, TSV, and advanced packaging. Geopolitically, while South Korea boosts domestic equipment amid U.S.-led export controls, core TC Bonder components remain dependent on U.S. and Japanese suppliers, leaving supply chains exposed. With Samsung fast-tracking HBM4 samples and Micron targeting edge AI via HBM-enabled PCs, SK hynix’s deep integration with NVIDIA’s Vera Rubin platform is a deliberate moat-building play. Over the next 18 months, HBM4 will become the AI chip performance gatekeeper; equipment ramp speed will decide who sets the 2027 AI server memory standard—and who gets excluded from the high-end stack.
