JASM / Kumamoto / JP
Specialty technology wafer fabrication
TSMC’s first specialty technology fab in Japan, at Kumamoto, began volume production at the end of 2024, and JASM began construction of a second facility on the site in 2025. TSMC states that with both fabs the Kumamoto site plans to offer 40, 22/28, 12/16, 6/7 and 3 nanometer process technologies for automotive, industrial, consumer electronics and HPC-related applications, and that it now plans to use 3nm process technology at the second fab to meet strong demand driven by AI. TSMC puts the overall investment in JASM above US$20 billion and expects the two fabs to directly create more than 3,400 high-tech professional jobs.

TSMC operates six 12-inch wafer GIGAFAB® fabs, four 8-inch wafer fabs, and one 6-inch wafer fab – all in Taiwan – as well as two 12-inch wafer fabs at two wholly owned subsidiaries – TSMC Nanjing Company Limited and TSMC Arizona Corporation, one 12-inch wafer fab at a TSMC’s majority-owned manufacturing subsidiary – Japan Advanced Semiconductor Manufacturing, Inc. (JASM), and two 8-inch wafer fabs at two wholly owned subsidiaries – TSMC Washington and TSMC China Company Limited.
KUMAMOTO, Japan, Feb. 24, 2024 – TSMC (TWSE: 2330, NYSE: TSM) today held an opening ceremony for its majority-owned subsidiary Japan Advanced Semiconductor Manufacturing, Inc. (JASM) in Kumamoto Prefecture, Japan, bringing together suppliers, customers, business partners, academia and the Japanese government to show appreciation for their continued support and the joint effort that led to the success of the project.
The opening marks a significant milestone for JASM, which was established in 2021 and started construction in April 2022, with production targeted to begin by the end of 2024.
