According to reports, the fab is jointly invested by TSMC, Sony, Denso Corporation and the Japanese government, with an amount of US$8.6 billion. The Japanese government owns about 50% of the
shares and hopes to use this to strengthen the supply chain of key components such as semiconductors to improve Japan's economic security. The factory is targeted to start shipping in December 2024, which JASM says will help alleviate a global semiconductor shortage.
JASM signed a land use agreement with Kikuyo Town on the same day. Reports indicate that JASM will employ a total of 1,700 employees, including 300 from TSMC and 200 from Sony.
