TSMC pivots on tooling
- TSMC unveiled its A13 process technology while saying it will delay using ASML’s costliest High-NA EUV machines. (businesswire.com) - The company also signalled U.S. onshore capacity is rising with plans for a chip-packaging plant in Arizona by 2029. (finance.yahoo.com) - That combination shifts the bottleneck toward packaging and efficient scaling rather than buying ever-more-expensive lithography tools. (bloomberg.com)
Taiwan Semiconductor Manufacturing Co. is rolling out a new chipmaking process while putting off ASML’s most expensive lithography machines until at least 2029. (bloomberg.com) At its North America Technology Symposium in Santa Clara on April 22, TSMC introduced A13, a process scheduled for production in 2029, one year after A14. The company said A13 offers 6% area savings from A14 and keeps design rules backward compatible so customers can move existing designs more easily. (businesswire.com) Lithography is the step that projects circuit patterns onto silicon, like using a stencil to print ever-finer lines. TSMC said its current extreme ultraviolet tools can keep shrinking chips through 2029, avoiding ASML’s newer High-NA machines for now because of cost. (finance.yahoo.com) The company is making a parallel bet on the step after wafer-making: packaging, which connects several chip pieces into one product. TSMC plans to open a packaging plant in Arizona by 2029, an executive told Reuters on April 22. (finance.yahoo.com) That matters because many artificial intelligence processors are no longer one large chip. Nvidia-style accelerators are often multiple dies joined with advanced packaging, and Reuters reported that packaging has become a supply bottleneck for Nvidia and other customers. (finance.yahoo.com) TSMC’s roadmap points the same way. At the symposium, it also previewed A12 with backside power delivery for artificial intelligence and high-performance computing, plus wafer-scale and 3D stacking technologies aimed at moving more data between chip pieces. (businesswire.com) The High-NA delay is also notable because TSMC is ASML’s largest customer, according to Bloomberg supply-chain data. Bloomberg reported the decision is a setback for the Dutch equipment maker’s push to get its priciest machines into volume chip production. (bloomberg.com) TSMC had already signaled caution on High-NA in 2024, when Vice President Kevin Zhang said the company’s existing extreme ultraviolet systems could support its near-term nodes. The April 2026 update extends that stance into the end of the decade and ties it to a production plan built around A13 in 2029. (bloomberg.com, bloomberg.com) So the near-term race is not just about etching smaller features onto wafers. TSMC is telling customers that cheaper scaling on existing extreme ultraviolet tools, plus more packaging capacity in Arizona, is enough to carry its next advanced node into production.
