TSMC to launch 3-nanometre chip production in Japan by 2028
Taiwan Semiconductor Manufacturing Co. plans to launch mass production of advanced 3-nanometre chips at its second factory in Japan in 2028, a strategic move to diversify its manufacturing footprint and solidify its technology leadership.
The plan was detailed in a Taiwanese government filing late on Tuesday, which outlined the timeline for equipment installation and mass production. "This expansion strengthens Japan's role in the global semiconductor supply chain and provides our customers with more resilient supply," a TSMC spokesperson said.
The new facility will focus on 3nm process technology, a significant leap from the 28nm and 12/16nm chips produced at its first Japan plant. While specific capacity figures were not disclosed, the 3nm node offers significant performance and power efficiency gains over previous generations, such as the 5nm node currently used in high-end smartphones and processors from competitors like Samsung Foundry.
This expansion is critical for TSMC's long-term valuation, diversifying its advanced manufacturing away from geopolitical risks in Taiwan. For Japan, it represents a major win in its efforts to rebuild its domestic semiconductor industry, attracting key players like TSMC and securing access to leading-edge technology that is vital for future advancements in AI, high-performance computing, and automotive sectors.
What's happening?
According to a Taiwanese government filing on March 31, 2026, TSMC is set to begin equipment installation for its second factory in Japan, with mass production of 3-nanometre wafers slated for 2028. This development confirms TSMC's commitment to expanding its global presence and diversifying its manufacturing capabilities beyond Taiwan. The project is a collaboration with Japanese partners, including Sony and Denso, to bolster Japan's domestic chip production.
Why it matters
The move to produce 3nm chips in Japan is a significant step for both TSMC and the Japanese government. For TSMC, it mitigates the geopolitical risks associated with concentrating its most advanced production in Taiwan. For Japan, it's a crucial part of a national strategy to regain a leading position in the semiconductor industry, a sector it once dominated. The availability of locally produced, high-end chips will be a boon for Japanese industries, particularly automotive and electronics, reducing their reliance on imports and strengthening supply chain resilience. This is a direct challenge to other foundry players like Intel Foundry Services, which is also trying to attract major customers.
What's next?
With a clear 2028 production target, the next steps will involve the construction of the factory and the installation of highly complex lithography equipment from suppliers like ASML. The success of this plant will be a key indicator of whether advanced semiconductor manufacturing can be effectively decentralized globally. The project's progress will be closely watched by the entire tech industry, as it could influence future investment decisions by other major chipmakers and governments seeking to secure their own domestic supply of critical semiconductor components.
