Taiwan Semiconductor Manufacturing Co.'s chairman said Thursday its Japan venture with a Sony Group Corp. subsidiary is a special case as the company typically seeks full ownership in overseas plants.

Mark Liu was referring to a $7 billion plant the world's largest contract manufacturer of semiconductor chips will build in Kumamoto Prefecture, as the company reported record net profit and sales in the business year through December.

"We have a very large customer who (has) a single technology, and we can also leverage their operating in manufacturing experiences in Japan, which helps ramp in the learning curve," Liu said during an online earnings call.

Amid a global chip shortage, TSMC announced in November the construction of the foundry in partnership with Sony Semiconductor Solutions Corp.

Construction is scheduled to begin this year, with production targeted to commence by the end of 2024. Sony Semiconductor Solutions will invest some $500 million, representing an equity stake of less than 20%.

The project, TSMC's first chip factory in Japan, is expected to create about 1,500 jobs for high-tech talent, the two companies said.

In December, Taiwan's Investment Commission approved the investment plan, supported by the Japanese government.

On Thursday, TSMC reported a net profit of 596.5 billion New Taiwan dollars ($21.62 billion) in the year through December, up 15.2% from a year earlier, on sales of NT$1.58 trillion, up 18.5%.

Looking ahead, Wendell Huang, TSMC vice president and chief financial officer, said the company will likely see continued recovery in the automotive segment, high-performance computing-related demand, as well as milder smartphone seasonality.
