TSMC leads multi-billion dollar expansion with second fab in Kumamoto, Japan


In a significant move to address the escalating demand for semiconductors, TSMC (TWSE: 2330, NYSE: TSM), together with Sony Semiconductor Solutions Corporation (“SSS”), DENSO Corporation (“DENSO”), and Toyota Motor Corporation (“Toyota”), has announced an additional investment into Japan Advanced Semiconductor Manufacturing, Inc. (“JASM”), TSMC’s majority-owned subsidiary located in Kumamoto Prefecture, Japan. This investment is aimed at constructing a second fabrication plant (fab), which is projected to commence operations by the end of 2027. This strategic expansion is expected to push the total investment in JASM beyond the US$20 billion mark, with substantial backing from the Japanese government.

The decision to erect a second fab, scheduled to start construction by the end of 2024, comes as a direct response to the growing customer demand for semiconductors. This expansion will not only escalate the production scale but also enhance the cost structure and supply chain efficiency for JASM. Upon completion, the Kumamoto site’s two fabs will boast a total production capacity exceeding 100,000 12-inch wafers per month. This capacity will support a range of process technologies—40, 22/28, 12/16, and 6/7 nanometers—catering to automotive, industrial, consumer, and high-performance computing (HPC) applications. Moreover, the production capacity may be further refined based on customer demands, ensuring agility and responsiveness to market needs.
