On October 19, 2026, TSMC announced a major expansion of its advanced 3-nanometer chip production. The company will build a new 3nm fab in Tainan, Taiwan. Production is scheduled to begin in the first half of 2028.
TSMC called the expansion part of an unprecedented pace of growth to meet soaring demand for its most advanced technologies.
Japan’s Ministry of Economy, Trade and Industry approved TSMC’s revised plan for its second plant in Kumamoto. The plant will also produce 3nm semiconductors, with production scheduled to begin by December 2028.
The expansions target robust long-term demand for high-performance chips from the AI and high-performance computing sectors. They underscore TSMC’s critical role in the global semiconductor supply chain.
