It was reported back in January that TSMC was investing in a 5nm chip fabrication process as part of its efforts to retain its sole supplier status for Apple’s A-series chips.

The company has now confirmed this report …


Reuters carried the news.

Taiwan Semiconductor Manufacturing Co Ltd, a supplier to Apple Inc, said on Thursday it expects to invest $25 billion in 5 nanometer node technology.

TSMC has had the exclusive contract for the A-series chips used in iPhones and iPads since the A9X used in the iPad Pro. It’s believed this is primarily due to the company’s lead over Samsung in ever-smaller processes.

Reuters says TSMC hasn’t announced a timeframe, though the previous report said that the company expected to hit volume production by 2020, and was already looking ahead to a 3nm process by 2022.

Samsung is reported to be working on a 4nm process, but no timeframe is known.
