TSMC Advanced Nodes and CoWoS Stay Tight Into 2027 as Packaging Race Widens

TSMC has for the first time outlined 2027 expansion targets, with 2nm capacity set to grow 22 percent and 3nm more than 16 percent between end-2026 and mid-2027, according to Economic Daily News supply chain sources cited by TrendForce. Concretely, 2nm capacity is expected to rise from 90,000 wafers per month at end-2026 to 110,000 by mid-2027, while the 3nm ramp goes from more than 180,000 to 210,000 wafers per month. The foundry is adding three 3nm fabs across Taiwan, Arizona and Japan and is converting 5nm equipment in Taiwan to support additional 3nm output. TSMC guided 2026 capital spending to 60 to 64 billion dollars, with about 70 to 80 percent allocated to advanced process technologies.

Advanced packaging is expanding just as aggressively. CoWoS capacity could double from roughly 130,000 wafers per month at end-2026 to 260,000 by end-2028, with the ramp centred on AP7 in Taiwan and the Arizona campus, where local packaging would reduce the need to ship advanced chips back to Taiwan. Rivals are moving too: analysts estimate Intel's EMIB-T capacity, measured in 12-inch CoWoS-equivalent wafers, could climb from 15,000 to 20,000 per month in 2027 to 40,000 to 45,000 in 2028, an architecture seen as well suited to custom accelerators from Google and Amazon. MediaTek has said Intel's EMIB packaging has reached a very good level, a signal that yields are improving.

Demand still outruns supply in the near term. DIGITIMES reports that TSMC's 3nm, 2nm and CoWoS capacity all remained in short supply through late third-quarter 2026, as changes in major customer orders and front-end and back-end supply models prompted the foundry to reallocate advanced capacity. The scramble is no longer only for wafers: advanced packaging has become the gating step that determines how much accelerator output can actually ship, and cloud customers are booking slots years ahead.

Equipment and geopolitics frame the longer horizon. Futurum Group estimates global wafer fab equipment spending could reach about 270 billion dollars by 2030, with one gigawatt of AI capacity requiring roughly 745,000 wafers and 6.1 billion dollars of wafer fab equipment investment. At the same time, about 20 of China's outsourced semiconductor assembly and test providers are pushing into advanced packaging as restrictions on leading-edge lithography complicate further process-node scaling. Tightness is not limited to the leading edge either: Germany's Elmos Semiconductor locked in wafer supply from SK keyfoundry through 2037 on 130nm technology as conditions tighten across parts of the 8-inch foundry market.
