The first fab shifted to N4, was delayed to 2025 because of a shortage of skilled equipment-installation workers, and entered volume production in late 2024; customers including NVIDIA, AMD and Apple have since cited Arizona-made chips or products. Federal CHIPS Act support and successive expansion plans have turned the Phoenix site into a proposed US$265 billion cluster of fabs, packaging facilities and R&D, with Fab 2 complete, Fab 3 topped out, and initial work started on Fab 4 and a packaging plant. The main uncertainty is timing and final process assignments for the later fabs: TSMC has repeatedly pulled schedules forward or revised node plans, while its newest US$100 billion expansion has no firm schedule.", "hero_image": "https://images.unsplash.com/photo-1551952284-47086cd96da5?ixid=M3w5OTg1Nzd8MHwxfGFsbHx8fHx8fHx8fDE3ODgzNTEzMjB8&ixlib=rb-4.1.0&w=1600&q=80&auto=format&fit=crop", "hero_credit": { "source": "unsplash", "photo_id": "9tQxbON36Q0", "photographer": "Raivis Razgals", "photographer_url": "https://unsplash.com/@rraivisr?utm_source=whatledto&utm_medium=referral", "photo_url": "https://unsplash.com/photos/people-walking-on-road-9tQxbON36Q0?utm_source=whatledto&utm_medium=referral", "description": "people walking on road", "license": "", "license_url": "" }, "entities": [ { "name": "AMD", "kind": "company", "role": "Customer that announced validation of fifth-generation EPYC products at TSMC’s Arizona fab." }, { "name": "Amkor", "kind": "company", "role": "Named by NVIDIA as an Arizona packaging-and-test partner." }, { "name": "Apple", "kind": "company", "role": "Said it expected to buy well over 100 million advanced chips made at TSMC’s Arizona facility in 2026." }, { "name": "Nvidia", "kind": "company", "role": "Customer that announced Blackwell production at TSMC’s Phoenix plants." }, { "name": "SPIL", "kind": "company", "role": "Named by NVIDIA as an Arizona packaging-and-test partner." }, { "name": "TSMC", "kind": "company", "role": "Taiwan-based chipmaker building and operating the Arizona fabs and announcing the site’s successive investment and technology plans." }, { "name": "TSMC Arizona", "kind": "company", "role": "TSMC’s Arizona operation, recipient of CHIPS Act support and operator of the Phoenix fabrication site." }, { "name": "Arizona", "kind": "other", "role": "US location of TSMC's fab site and Phoenix chip plants." }, { "name": "City of Phoenix", "kind": "other", "role": "Reported local construction milestones, including the Fab 3 topping-out ceremony and initial work on Fab 4 and a packaging plant." }, { "name": "Fab 3", "kind": "other", "role": "TSMC Arizona's third fab, which held a topping-out ceremony." }, { "name": "Taiwan", "kind": "other", "role": "Comparison location for TSMC fab construction costs and reported chip yields." }, { "name": "C.C.
