TSMC hits capacity limits
TSMC looks set to post a fourth straight quarter of record profit as AI demand keeps chip orders strong, but the company and Taiwan more broadly are bumping into physical limits—land, advanced packaging and science‑park capacity are all tight. TSMC is investing in advanced‑packaging sites in Arizona and elsewhere, but those facilities are not expected to reach mass production until around 2030, keeping near‑term packaging a bottleneck.

Taiwan Semiconductor Manufacturing is making more artificial intelligence chips than ever, but it is running short of the space and packaging lines needed to finish them. (reuters.com) Analysts told Reuters that TSMC’s January-to-March net profit likely rose about 50% from a year earlier, which would mark a fourth straight quarterly record if it tops the company’s prior high. TSMC is scheduled to report first-quarter 2026 results on Thursday, April 16. (reuters.com, investor.tsmc.com) The squeeze is not only inside TSMC’s factories. DigiTimes reported this week that Taiwan’s science parks are nearing full capacity as semiconductor investment led by TSMC absorbs available land, power and infrastructure. (digitimes.com) One bottleneck sits after the chip is made. Advanced packaging is the step that connects a processor to stacks of high-bandwidth memory inside one module, and TSMC’s CoWoS process is built for artificial intelligence and supercomputing chips. (tsmc.com) That matters because a finished artificial intelligence accelerator needs both the silicon wafer and the package around it. Even if TSMC can etch more chips, customers still have to wait if the packaging line is full. (tsmc.com, reuters.com) TSMC is adding capacity in Taiwan and the United States, but the relief is not immediate. Reuters reported that the company is investing in advanced-packaging sites in Arizona and elsewhere, while outside reports say the Arizona packaging build-out is aimed at production closer to the end of the decade. (reuters.com, gpec.org, tsmc.com) The Arizona project is already large on the front-end manufacturing side. TSMC says its first Arizona fab has started volume production on 4-nanometer chips, a second fab is planned for 3-nanometer and 2-nanometer technology, and a third fab is targeting 2-nanometer and A16 production by the end of the decade. (tsmc.com) The near-term problem is that chipmaking and chip-finishing do not expand at the same speed. New fabs can add wafer output, but advanced packaging needs its own buildings, tools and engineers, and those are now scarce in Taiwan as demand from Nvidia and other artificial intelligence customers stays high. (reuters.com, digitimes.com) TSMC has started laying out the next packaging technologies as package sizes grow. TrendForce reported on April 13 that TSMC is also preparing a pilot line for chip-on-panel-on-substrate, or CoPoS, with a broader ramp eyed for 2028 to 2029. (trendforce.com) For now, the company’s earnings are still rising faster than its physical footprint. TSMC can post another record quarter on April 16 and still leave the artificial intelligence industry waiting for more land, more power and more packaging slots.
