Hybrid Bonding for HBM Delayed to Decade's End, Logic Adoption Advances

By PulseAugur Editorial · [2 sources] ·

Hybrid bonding, a copper-to-copper chip joining technique, is in high-volume production for logic chips but its adoption for High Bandwidth Memory (HBM) has been delayed. A recent JEDEC decision allows HBM4 to continue using less advanced microbump technology, pushing hybrid bonding's debut in HBM to HBM4E and HBM5 by the end of the decade. While TSMC is advancing its hybrid bonding pitch and Intel has implemented it in server CPUs, the memory sector's delay is attributed to this JEDEC decision. AI

IMPACT This delay in HBM adoption could impact the performance and cost of AI accelerators that rely on high-bandwidth memory.

RANK_REASON The article details advancements in chip manufacturing technology (hybrid bonding) and a significant delay in its application to a key memory standard (HBM), impacting the semiconductor industry's roadmap.

    The current state of Hybrid Bonding in 2026 — TSMC sits at 6 microns and the HBM delay that nobody expected

    Hybrid bonding, the copper-to-copper joining technique that replaces solder microbumps in 3D chip stacks, is in high-volume production on logic and freshly postponed on memory.
