TSMC Confirms New 3nm Fab in Japan
TSMC has officially confirmed it will build a 3nm fabrication facility in Japan, set to begin operations by 2027. This move marks a significant diversification of advanced-node capacity away from Taiwan and the US. It's a key part of the industry's race to hedge against geopolitical risk and could ease future supply constraints for major clients like Apple.
This new 3nm facility is an expansion of TSMC's existing presence in Japan's Kumamoto Prefecture, representing a significant upgrade to its second fab at the site. The total investment in the two fabs by TSMC and its partners is expected to exceed $20 billion, with the Japanese government providing substantial subsidies totaling around ¥1.2 trillion (approximately $8 billion USD) for both plants. The project, a joint venture named Japan Advanced Semiconductor Manufacturing (JASM), includes major Japanese corporations as minority stakeholders. Sony Semiconductor Solutions, automotive components manufacturer Denso, and Toyota have all invested in the venture. With the new investment for the second fab, TSMC's equity stake in JASM will be approximately 86.5%, with Sony holding 6.0%, Denso 5.5%, and Toyota 2.0%. Initially, the second fab was planned for more mature processes like 6/7nm chips. However, TSMC CEO C.C. Wei confirmed the upgrade to 3nm technology, citing soaring global demand for AI chips, positioning Japan as a key location for producing the world's most advanced semiconductors. This move aligns with Japan's broader strategy to revitalize its once-dominant semiconductor industry, a plan spearheaded by the Ministry of Economy, Trade and Industry (METI). The first JASM fab, which began construction in April 2022, focuses on 12/16nm and 22/28nm processes for clients like Sony, and entered mass production in late 2024. Construction on the newly announced 3nm fab is set to begin by the end of 2024, with operations scheduled to start by the end of 2027. Together, the two fabs are expected to create more than 3,400 high-tech professional jobs. When both fabs are fully operational, the Kumamoto site is projected to have a total monthly production capacity of more than 100,000 12-inch wafers. This major production hub on the southern island of Kyushu is helping it earn the nickname "Silicon Island," reminiscent of its role as a chipmaking hub in the 1980s. The initiative is seen as critical for Japan's economic security, ensuring a stable domestic supply of advanced logic chips.
