TSMC chooses thrift

Taiwan Semiconductor Manufacturing Co. said on April 22 it can keep shrinking chips through 2029 without buying ASML’s costliest next-generation lithography tools. (reuters.com) At TSMC’s North America Technology Symposium in Santa Clara, the company introduced its A13 manufacturing process and said it is scheduled for production in 2029, one year after A14. TSMC said A13 is a direct shrink of A14 and is aimed at artificial intelligence, high-performance computing and mobile chips. (tsmc.com) Chip lithography is the step that prints circuit patterns onto silicon, and ASML’s High-NA extreme ultraviolet machines are the newest version of that tool. TSMC deputy co-chief operating officer Kevin Zhang said the company can still “harvest the benefit” from today’s extreme ultraviolet systems through 2029 instead of moving sooner to High-NA. (reuters.com (electronicsweekly.com) That choice centers on cost. ASML’s High-NA Twinscan EXE tools were priced at about 350 million euros, or roughly $380 million, compared with about 170 million euros for current low-NA extreme ultraviolet systems. (yolegroup.com) TSMC is pairing that thrift with more spending on packaging, the step that links several pieces of silicon into one processor package. Reuters reported on April 22 that TSMC plans to open a packaging plant in Arizona by 2029, extending work now centered in Taiwan. (reuters.com) That matters because many artificial intelligence chips are no longer one big die. Nvidia-style accelerators often combine multiple compute and memory chips in one package, making packaging capacity almost as strategic as the wafer fab itself. (reuters.com) TSMC also used the event to show how far it thinks existing tools can be stretched. Reuters reported that the company laid out a roadmap to 2029 with A13 and other process updates while holding off on High-NA deployment for that period. (reuters.com) For customers, the pitch is continuity. TSMC said A13’s design rules are fully backward compatible with A14, which lets chip designers move existing designs to the newer process faster and with less redesign work. (tsmc.com) For ASML, the message is narrower than a rejection. TSMC said it does not need High-NA immediately, not that the tool has no future, and analysts told Reuters the company could still adopt it later as scaling gets harder. (reuters.com) So the 2029 roadmap now looks less like a race to buy every new machine and more like a bet that careful process tuning and more packaging can keep chip gains coming. TSMC’s next test is whether customers keep getting smaller, faster chips on that cheaper path. (reuters.com (reuters.com)
