SK hynix has placed its first order for mass-production hybrid bonding equipment jointly developed by Applied Materials and Besi. The equipment, valued at approximately 20 billion won, is intended for the development of next-generation High Bandwidth Memory (HBM). This technology enables direct copper-to-copper bonding, significantly improving integration density and thermal performance compared to traditional microbump methods. The move signals a strategic shift toward advanced packaging for future HBM4 products and beyond, which are essential for demanding AI workloads. By adopting this technology early, SK hynix aims to maintain its dominant position in the highly competitive AI memory market. This milestone also underscores the growing industry transition to hybrid bonding as a new standard for high-end semiconductor manufacturing.
