TOKYO, Feb 5 (Reuters) - TSMC plans to mass produce advanced 3-nanometre chips in Kumamoto in southern Japan with investment totalling $17 billion, ‌Japanese newspaper Yomiuri reported on Thursday.

Japan's government, ​which has subsidised Taiwan's leading chipmaker ‍to build out capacity ⁠in Kyushu, ⁠is considering additional support for the new investment ‌plan, Yomiuri reported.

TSMC ​had planned to invest $12.2 billion on 6-12 nanometer chipmaking capacity ⁠at its second ‍fab ​in Kyushu but will discuss changes to the plan with Japan's government, ‍Yomiuri reported.

TSMC did not immediately respond to a request for comment.

Japan is also heavily subsidising homegrown foundry venture Rapidus, which will ​produce ‍cutting-edge chips on the northern island of Hokkaido.

The government has determined ​the two companies' chips will have different uses and will not be in competition, Yomiuri reported.

Securing access to chips, which are critical for electronics, automotive ​and defence industries, has become a priority for governments around the world.
