TSMC CoWoS, Foundry Capacity and AI Chip Supply — 2026-09-26
This week's focus: TSMC has confirmed a 3–6% wafer price increase from January 2027 with orders fully booked through 2030. Taiwan's press highlights the groundbreaking of a Kaohsiung advanced-packaging validation base led by TSMC, plus UBS upgrades across 11 Taiwan supply-chain names on CoWoS momentum. N2 and N3 capacity ramps remain on an accelerating track, with a new Arizona fab slated for 2027.
TSMC CoWoS, Foundry Capacity and AI Chip Supply — 2026-09-26
Top developments
TSMC confirms 3–6% price hike from January 2027; order book full through 2030
Supply-chain sources say TSMC will raise wafer-out prices by roughly 3–6% starting January 2027, adjusted by process node, with 8-inch fabs running above 100% utilization and all nodes below 45nm fully loaded. TechTimes reports the 3–6% floor is narrower than the 8–10% Wall Street had projected, but AI chip buyers could see total costs rise 20% or more once HPC overflow surcharges stack on top. Full-capacity visibility through 2030 signals this may be only the first of several increases.
Kaohsiung's Bapu park breaks ground on advanced packaging validation base
On September 21, ground was broken at Kaohsiung's White Bu (Bapu) Industrial Park for an ~89-hectare semiconductor equipment and materials validation base, with TSMC committing roughly 3 hectares for a "mini-loop" modular verification line and small cleanrooms. The goal is to cut equipment validation feedback time by 25–50%, speeding the ramp of CoWoS and 2nm expansion, and the government estimates up to NT$300 billion in annual output value. MoneyDJ asked directly whether the platform can relieve the CoWoS capacity gap.
UBS upgrades CoWoS outlook, buys 11 Taiwan names
UBS raised its CoWoS capacity forecast and simultaneously placed buy ratings on 11 Taiwan-listed companies, arguing the expansion benefits go well beyond TSMC itself. The bank estimates advanced packaging revenue could account for 12% and 16% of relevant companies' 2026 and 2027 revenue, with ~50% CAGR through 2030, while advanced packaging test-equipment makers also benefit from increasingly complex package structures.
N2/N3 capacity figures firm up; Arizona fab to join 3nm in 2027
Taiwan's United Daily News (UDN/Economic Daily) reports supply-chain expectations that TSMC's 2nm monthly capacity will reach about 90,000–100,000 wafers by end-2026 and approach 110,000–140,000 in 2027, while Southern Taiwan Science Park 3nm capacity hits nearly 180,000 wafers per month in Q4 2026, possibly nearing 200,000–210,000 by 2027 (+16% y/y). TSMC is adding three 3nm fabs — in Taiwan and at Arizona, with the new US fab targeted for 2027 production. TSMC shares re-crossed the NT$2,500 mark on the news. TechBang adds TSMC is spending over US$60 billion on the 2nm/3nm expansion and has pre-secured ASML next-generation (High-NA) masks.
CoWoS overflow spills to Taiwan suppliers: ASE, substrate makers are big winners
SETN reports ASE Technology Holding (3711) is riding CoWoS overflow plus AMD's new CPU ramp; analysts keep a buy rating with a target price up to NT$862, noting a Q2 profit up 180% y/y. Separately, China Times cites reports that CoWoS demand is surging 125%, making equipment vendors KLA, Applied-like test players and others "hidden winners" — KLA's fiscal Q4 revenue reached US$3.66 billion, up 15.2% y/y. Substrate makers Unimicron, Nan Ya PCB and Kinsus are described as the three big Taiwan winners as substrates become "hard to get even with money."
Local view
Taiwan's United Daily News and Economic Daily celebrated TSMC re-crossing NT$2,500 and laid out the 2nm/3nm capacity roadmap in detail. MoneyDC/MoneyDJ framing centered on whether the Kaohsiung validation base can "relieve the CoWoS capacity gap," stressing the mini-loop line's 25–50% faster validation loop. UDN also reported chemical suppliers (Chang Chun, San Fu, Nan Pao, Everlight) positioning for the advanced-packaging materials battlefield as CoWoS volumes scale and wafer-level multi-chip modules ramp. Economic Daily flagged that TSMC's A16 process will enter mass production in Q4 2026, with ASE, China Sand (1560), and Sun Semi (8028) named as beneficiary suppliers.
Context & numbers
- 2027 wafer price hike: 3–6% by node, effective January 2027; visibility to 2030.
- CoWoS demand up ~125%, driving test/inspection equipment demand (KLA FQ4 revenue US$3.66bn, +15.2% y/y).
- N2 monthly capacity: ~90–100k wafers by end-2026, 110–140k by 2027; N3 at Southern Taiwan Science Park: ~180k wpm in Q4 2026, potentially 200–210k by 2027.
- 2026 CapEx: US$60–64 billion, mostly toward 2nm/3nm and CoWoS expansion.
- Bapu Industrial Park: ~89 ha total, TSMC ~3 ha, projected NT$300bn annual output value.
- TSMC holds >90% of global CoWoS output; monthly capacity ~90,000 wafers heading to ~120,000 by year-end per TrendForce-cited estimates (context from July).
On the radar
- Q4 2026 mass production of the A16 backside-power node — watch supplier alignment around ASE, China Sand, and Sun Semi.
- The new Arizona 3nm fab's 2027 qualification and whether US-made 3nm wafer allocation affects Taiwan CoWoS loading.
- Rumor watch: TechTimes flags possible "HPC overflow surcharges" of 20%+ on top of the 3–6% base increase — a rumor until contract terms surface.
- Monthly revenue report: TSMC's September consolidated revenue will publish around October 10 on its IR site; watch CoWoS-linked strength in August/September figures.
