TSMC delays high‑NA push
- TSMC announced it can produce smaller, faster chips without immediately adopting ASML’s newest high‑NA EUV machines. - The company said this delays expensive high‑NA adoption and keeps chip progress flexible for now. - That flexibility broadens inference hardware assumptions while U.S. export‑control talks and China’s domestic accelerator build‑out reshape supply chains ( ).
TSMC said on April 22 it can keep shrinking chips for years without buying ASML’s newest high‑NA lithography machines. (reuters.com) At its North America Technology Symposium in Santa Clara, TSMC said its A14 process is still on track for production in 2028, with A13 planned for 2029. Deputy co-chief operating officer Kevin Zhang said the company has no current plan to use high‑NA tools before then. (reuters.com) Chip lithography is the step that projects circuit patterns onto silicon, like printing ever-smaller lines onto a wafer. ASML’s first high‑NA extreme ultraviolet system, the EXE:5000, uses 0.55 numerical aperture optics and is designed to print features 1.7 times smaller than earlier EUV systems in a single exposure. (asml.com) TSMC’s argument is that it can still get more out of today’s EUV tools. The company says A14 can deliver up to 15% higher speed at the same power or cut power by up to 30% at the same speed versus N2, while increasing logic density by more than 20%. (tsmc.com) Reuters reported the high‑NA machines cost about $400 million each, and Electronics Weekly put the figure at about $350 million. Delaying that purchase lets TSMC push node upgrades with lower capital intensity while it fills demand for artificial-intelligence and smartphone chips. (reuters.com (electronicsweekly.com) That stance lands in the middle of a supply-chain fight over who can build the fastest artificial-intelligence hardware and with which tools. The House Foreign Affairs Committee advanced a package of export-control bills on April 22 covering semiconductor equipment, enforcement, and artificial-intelligence exports, according to Legis1 and Bloomberg. (legis1.com (bloomberg.com) One bill in that package, H.R. 8170, targets semiconductor manufacturing equipment and components, according to the bill text on Congress.gov. Another, H.R. 6058, would set up a multilateral framework for semiconductor technology supply-chain coordination, according to Legis1’s summary of the hearing agenda. (congress.gov (legis1.com) China is moving in parallel on the demand side, backing domestic accelerator and artificial-intelligence server build-outs as access to top-end U.S. chips stays constrained. In that environment, a foundry roadmap that relies longer on existing EUV tools gives chip designers more ways to plan products around what fabs can actually ship. (reuters.com (legis1.com) TSMC is not saying high‑NA is unnecessary forever; it is saying the timing is not forced yet. For now, the world’s biggest contract chipmaker is betting that better transistor design and heavier use of current EUV machines can carry its roadmap through 2029. (reuters.com)
