TAIPEI--Taiwan Semiconductor Manufacturing Co. (TSMC) is considering building a second chip plant in Japan in addition to one it is constructing in Kumamoto Prefecture to boost production, according to the company.

TSMC Chief Executive Officer C.C. Wei said at a news conference on Jan. 12 that he is willing to go along with the plan, provided that demand grows in Japan and the Japanese government offers enough support.

Wei didn’t specify the possible location of the second plant.

The world’s largest contract chipmaker is currently constructing its first foundry in Japan, in a joint project with Sony Group Corp. and Denso Corp. The Japanese government is providing a subsidy of up to 476 billion yen ($3.68 billion) for the project.

The plant in Kikuyo, Kumamoto Prefecture, is scheduled to open in 2024.  Semiconductor chips with circuit widths of 22 to 28 nanometers, along with 10- to 20-nanometer chips, will be produced at the plant, according to TSMC.
