TSMC increases Arizona internships to feed its Phoenix fabs — CHIPS-fueled supply chain begins to take shape

TSMC has more than doubled its Arizona internship program, pulling in over 200 students from around 60 colleges this summer as it races to staff its advanced-node fabs just outside Phoenix. Just a year ago, that figure stood at 130. In 2023, it was only 16. Speaking to Phoenix Business Journal, TSMC Arizona president Rose Castanares said “we’re really scaling up,” noting that about 30 of this year’s interns came from Arizona State University alone.

TSMC began producing 4nm chips at its first Phoenix fab in early 2025, a milestone confirmed by both the company and the U.S. Commerce Department in April. That same announcement outlined $6.6 billion in CHIPS Act subsidies and the plan for a third Arizona fab — one that will eventually support TSMC’s upcoming 2nm process. Combined, the three fabs are expected to support over 6,000 direct jobs and produce some of the world’s most advanced silicon on U.S. soil.

TSMC is also using Amkor’s new $2 billion advanced packaging facility in nearby Peoria, which will handle CoWoS and InFO: Two essential technologies for stacking high-performance chips like GPUs, AI accelerators, and Apple’s multi-die SoCs. That move keeps a larger share of the chip supply chain in the U.S., especially for components built for the likes of Nvidia and AMD.
