Samsung expects HBM to account for nearly 30% of total DRAM production in 2027. - 超能网

Samsung's target of HBM reaching nearly 30% of DRAM output by 2027 is not a product roadmap—it is a structural repricing of the memory industry's value chain. Technically, TSV stacking and advanced packaging will cannibalize standard DRAM wafer capacity. The 16-high stack's dependence on advanced logic nodes for base dies forces Samsung to reallocate resources toward 4nm/3nm foundry lines. Upstream hybrid bonding equipment orders (Applied Materials, BESI) will be locked in early, while passive DDR5 capacity contraction likely triggers a commodity memory price cycle by H2 2026. On compliance, HBM's advanced packaging is tightly coupled to CoWoS-class processes. Under U.S. export controls, Samsung's Xi'an fab faces tighter audit scrutiny on capacity allocation. Any base-die overflow to foundry partners in Taiwan, China would materially raise supply-chain compliance costs. Competitively, SK Hynix holds the dominant NVIDIA HBM3E supply position. Samsung's aggressive capacity push is fundamentally a volume-for-certification play. If Micron's HBM3E ramp slips another quarter, Samsung secures the second-source slot by Q2 2026. The real bottleneck over the next 18 months is not wafers but advanced packaging yield. Whoever cracks CoWoS-L first owns HBM4 pricing power. Samsung is betting on exactly that window.
