HBM and Semiconductor Capacity Expansion Reshapes Electronics Supply Chains - Astute Group

The rapid advancement of semiconductor technology is fundamentally reshaping global electronics supply chains through HBM (High Bandwidth Memory) development and semiconductor capacity expansion. HBM ... Read original →

The surge in HBM adoption is fundamentally altering the co-design paradigm between memory and logic chips, turning advanced packaging—particularly CoWoS—into the new supply chain chokepoint. Upstream equipment makers like ASML and Applied Materials benefit from soaring demand for TSV and hybrid bonding processes, while downstream AI server vendors face structural BOM cost inflation. Geopolitically, the concentration of OSAT capacity in Taiwan, China and Hong Kong, China heightens 'tech decoupling' risks, with U.S. export controls likely pushing compliance costs up by over 30%. Samsung and SK hynix are racing to HBM4 to outflank Micron, while TSMC deepens its CoWoS moat by locking in NVIDIA and AMD. Within 18 months, second-tier DRAM players lacking advanced packaging capabilities will be squeezed out of the high-end market, consolidating global HBM supply into a tri-polar yet duopoly-dominated structure and accelerating nationalized capacity strategies worldwide.
