TSMC to expand in Arizona
What happened
- TSMC plans an advanced chip-packaging plant in Arizona, targeted to open by 2029. - The onshore packaging aims to shorten logistics for US-made chips and reduce reliance on cross‑Pacific returns. - TSMC also disclosed a process roadmap through 2029 and is deferring costly High‑NA EUV deployment for now.

Why it matters
TSMC says it plans to open an advanced chip-packaging plant in Arizona by 2029, adding a missing manufacturing step to its U.S. site. (reuters.com) The company disclosed the target on April 22 in Santa Clara, where vice president Kevin Zhang told Reuters the Arizona packaging plant would open by 2029. TSMC had said in a January earnings call that it was seeking permits for its first advanced packaging plant at an existing Arizona facility, but it had not given an opening date. (reuters.com) Packaging is the stage where several pieces of silicon are combined into one finished processor, a layout used in many artificial-intelligence chips. Reuters reported that this step has become a supply bottleneck for Nvidia and other customers, and that U.S.-made chips now often still need to go back across the Pacific for that work. (reuters.com) TSMC’s Arizona site was already set up to handle wafer fabrication, the front-end step that etches circuits onto silicon. The packaging plant would add back-end work onshore, cutting one of the longest logistics loops in the company’s U.S. production chain. (nist.gov) (reuters.com) The Arizona expansion sits inside a much larger U.S. buildout. TSMC Arizona says the first fab is on track for high-volume production in the first half of 2025, the second fab is scheduled for 2028, and the third fab is targeted by the end of the decade. (nist.gov) (tsmc.com) The U.S. government tied money to that expansion in 2024, when the Commerce Department announced an award of up to $6.6 billion in direct CHIPS Act funding for TSMC Arizona. The project also included plans for a third Phoenix fab and thousands of manufacturing and construction jobs. (nist.gov) (tsmc.com) TSMC paired the Arizona packaging news with a longer process roadmap through 2029 at its North America Technology Symposium. In an April 22 release, the company said its new A13 process is a shrink of A14, and it previewed A12 with backside power delivery, with A12 scheduled to enter production in 2029. (tsmc.com) The company is also holding off on ASML’s High-NA extreme ultraviolet tools for now. Electronics Weekly reported Zhang said TSMC could keep using its current extreme ultraviolet equipment through 2029 instead of moving to the newer machines, which the trade publication said cost about $350 million each. (electronicsweekly.com) That choice keeps TSMC’s Arizona story focused on finishing more of the chip in one place, not just printing smaller transistors. If the 2029 target holds, chips started in Phoenix will have fewer reasons to leave the United States before they are ready for customers. (reuters.com)
