   SK Hynix Integrates Intel EMIB for Next-Gen HBM Packaging

   SK Hynix is shifting its HBM strategy toward advanced packaging to address bottlenecks in thermal management, power consumption, and stack height. At Hot Chips 2026, the company revealed a roadmap incorporating Intel EMIB-T packaging and hybrid bonding, while continuing collaboration with TSMC for CoWoS-L, CoWoS-S, and CoWoS-R integration. The company has already entered mass production for 12-layer HBM4 chips and is currently qualifying 16-layer versions. This transition marks a broader industry shift where packaging technology is becoming more critical than raw memory performance.

   Why it matters

   High Bandwidth Memory is essential for AI workloads, but increasing capacity and bandwidth create heat and power challenges. By utilizing 3D structures and advanced interconnects, manufacturers can maintain performance gains as stack heights climb.

   What is confirmed

   • SK Hynix has started mass production of 12-layer HBM4 chips.
   • 16-layer HBM4 chips are currently in the qualification phase.
   • SK Hynix is collaborating with TSMC to integrate HBM into CoWoS-L, CoWoS-S, and CoWoS-R.
   • The HBM competition is shifting from memory performance to packaging technology.

   Still unconfirmed

   • SK Hynix is using Intel EMIB-T packaging for its next-generation HBM memory.
   • SK Hynix has developed NAND-linked memory that reduces DRAM use to one-16th.
   • SK Hynix is moving toward a roadmap that includes hybrid bonding and 3D integration.

   What to watch next

   • Confirmation of 16-layer HBM4 qualification completion
   • Official product launch dates for HBM4 using EMIB-T packaging
