SK hynix launches iHBM integrated cooling solution for next-generation AI memory chips - Vietnam Investment Review - VIR

SK hynix has launched its iHBM (integrated high-bandwidth memory) solution to address thermal challenges in next-generation AI memory chips. As demand for AI and high-performance computing grows, HBM ... Read original →

By embedding cooling elements directly into the D2D PHY layer, SK hynix isn’t just solving HBM’s thermal bottleneck—it’s redefining thermal design paradigms for AI chips. This forces upstream material suppliers to accelerate low-CTE, high-thermal-conductivity underfill development, while downstream GPU designers can simplify system-level cooling. Under tightening U.S.-Japan-Netherlands export controls, reliance on advanced WLP and MR-MUF processes risks supply chain fragility and higher localization costs. Facing Samsung’s X-Cube and Micron’s hybrid bonding, SK hynix seizes narrative control in AI memory, compelling rivals to respond on thermal management. Within 18 months, iHBM could become standard in premium AI accelerators, driving SiP ecosystems toward 'thermally aware packaging' and forcing EDA vendors to integrate thermo-electrical co-simulation.
