Packaging is the chokepoint
TSMC’s CoWoS packaging is a material bottleneck for AI silicon—capacity talks cite moves from ~35K to ~130K wafers/month yet packaging is at full utilization and NVIDIA reportedly claims about 60% of CoWoS capacity for GPUs (x.com). Industry analysts warn wafer production is ~20% behind demand, memory prices are up ~25–30%, and AI‑driven memory/wafer tightness could persist toward 2030, implying multi‑year supplier lock‑ins ( ).
Morgan Stanley’s note behind the recent reporting breaks CoWoS demand down to specific wafer counts — it projects roughly 595,000 CoWoS wafers tied to a single major customer in 2026, with about 510,000 of those expected to flow through TSMC’s lines. (semimedia.cc) TSMC is routing that expansion through new advanced‑packaging sites — AP7 in Chiayi and AP8/Tainan are explicitly named in supply‑chain plans and expected to carry the bulk of next‑wave CoWoS output as tool move‑ins proceed through 2026–27. (trendforce.com) (taiwannews.com.tw) Industry forecasts that underlie those allocation numbers put total global CoWoS demand near 1 million wafers in 2026, a scale that forces large buyers to sign multi‑year commitments to secure slices of production. (eu.36kr.com) SK Group chairman Chey Tae‑won told reporters at GTC that the wafer shortage is structural and likely to persist through 2030, a timeline echoed by TrendForce estimates that wafer supply could run about 20% short of demand in the near term. (money.usnews.com) (trendforce.com) Market research groups and vendors are already quantifying the price impact: Counterpoint and EE Times flag contract‑price uplifts in late‑2025 of roughly 30% with further increases into early 2026, while TrendForce reported DRAM revenue jumps and S&P Global notes suppliers shifting capacity toward HBM at the expense of legacy DRAM. (counterpointresearch.com) (eetimes.com) (spglobal.com) To relieve the choke, TSMC has formalized partnerships to outsource advanced packaging: a memorandum with Amkor to provide turnkey packaging and test services in Arizona is public, and OSAT partners are expanding to absorb overflow. (pr.tsmc.com) (amkor.com) Market commentary and earnings notes show the practical consequence — major cloud and AI hardware buyers have already reserved multi‑year packaging slots and in some cases pre‑paid for wafers, leaving smaller ASIC and accelerator makers facing multi‑year lead times.
