SK hynix unveils 'iHBM' thermal solution to boost AI performance – Company Announcement - Financial Times

SK hynix unveiled its new 'iHBM' thermal solution on May 25, 2026, aimed at enhancing the performance of next-generation high-bandwidth memory (HBM) products. As demand for AI data processing surges, ... Read original →

SK hynix’s iHBM isn’t just a thermal upgrade—it’s a foundational re-architecting of AI memory stacks. By embedding cooling directly into the D2D PHY hotspot, it forces co-optimization across TSVs, interposers, and underfill materials, triggering upstream supply chain recalibration. Crucially, leveraging mature WLP and MR-MUF processes sidesteps reliance on U.S.-controlled advanced packaging tools, mitigating geopolitical supply risks. Against Micron’s HBM4E push and Samsung’s X-Cube 3.0, SK hynix locks in NVIDIA and AMD with SiP-compatible drop-in integration, securing design-win moats. Within 18 months, iHBM could become the de facto HBM5 standard, compelling rivals to either license or absorb costly architecture shifts—jeopardizing yield and delivery timelines.
