2nm Demand vs. Yield

A chip “yield” is the share of working chips that come off a silicon wafer, and right now that number is separating the 2-nanometer race into leaders and laggards. Taiwan Semiconductor Manufacturing Company is already in volume production on 2-nanometer in Taiwan, while Samsung Electronics is still being judged on whether its yields are high enough to ship at scale. (tsmc.com) (sammobile.com) On April 13, 2026, Reuters reported that Taiwan Semiconductor Manufacturing Company is expected to post a fourth straight quarter of record profit, with analysts forecasting a roughly 50% jump in January-to-March net income as artificial intelligence infrastructure spending stays strong. The company had already reported a 35% rise in first-quarter revenue on April 10. (reuters.com 1) (reuters.com 2) Taiwan Semiconductor Manufacturing Company has said its 2-nanometer, or N2, process started volume production in the fourth quarter of 2025, using nanosheet transistors instead of the fin field-effect transistors used in earlier generations. The company says N2 is aimed at artificial intelligence, mobile, and high-performance computing chips, and its N2P follow-on is scheduled for volume production in the second half of 2026. (tsmc.com 1) (tsmc.com 2) That matters because a “2-nanometer” label does not mean much on its own if a foundry cannot turn enough good dies out of each wafer to make customer orders economical. Industry reports cited by SamMobile said Samsung Foundry’s 2-nanometer yield is about 55%, still below the roughly 60% level commonly treated as the floor for stable mass production, and potentially lower after later packaging steps. (sammobile.com) Samsung’s position is contested in public reports. TrendForce, citing Korean media on March 31, said Samsung’s upper-end 2-nanometer yields had moved above 60%, while other recent reports said the company still remained short of that mark, showing how much of the yield debate still rests on supplier and industry sourcing rather than audited disclosures. (trendforce.com) (businesskorea.co.kr) Taiwan Semiconductor Manufacturing Company has been telling investors for months that customer interest in 2-nanometer is unusually broad. In its 2025 annual meeting materials and 2024 annual report, the company said “almost all” integrated-circuit innovators were working with its N2 platform before mass production began. (tsmc.com 1) (tsmc.com 2) The United States build-out shows the same problem in a different form: transferring a process is not the same as announcing one. Taiwan Semiconductor Manufacturing Company says its first Arizona fab entered high-volume production on 4-nanometer in the fourth quarter of 2024, its second fab is targeting 3-nanometer production in the second half of 2027, and its third fab is slated for 2-nanometer and A16 by the end of the decade. (tsmc.com) Arizona has also exposed the cost of recreating Taiwan’s manufacturing system abroad. Research from the Institute for Security and Development Policy and reporting from Rest of World describe labor shortages, training demands, higher costs, and disputes over the use of workers from Taiwan as recurring obstacles during the Phoenix ramp. (isdp.eu) (restofworld.org) Taiwan Semiconductor Manufacturing Company has said the first Arizona fab reached yields comparable to its Taiwan fabs, but that claim applies to 4-nanometer, not to the newer 2-nanometer node now driving the industry race. The next test is whether demand for the most advanced artificial-intelligence chips keeps outrunning the industry’s ability to make them in volume. (aztechcouncil.org) (tsmc.com)
