SK Hynix launches iHBM solution

SK Hynix has launched its iHBM solution, a new thermal management technology designed for next-generation high-bandwidth memory (HBM) products, including HBM5. This solution embeds integrated cooling elements (ICEs) directly within the HBM package, specifically in the Die-to-Die Physical Layer (D2D PHY) area, to create an additional heat dissipation path. This structural approach reduces thermal resistance by 30%, allowing chips to operate stably in high-temperature and high-pressure environments. The technology leverages SK Hynix's market-proven Mass Reflow Molded Underfill (MR-MUF) technology and Wafer Level Packaging (WLP) process, ensuring stable mass production and high design compatibility with existing System-in-Package (SiP) architectures. The iHBM solution aims to address critical heat management challenges in AI data processing and high-performance computing, enhancing overall system stability and operational efficiency.
