TSMC's Arizona plant will start making 4nm chips for Apple in 2024

Taiwan Semiconductor Manufacturing Co. (TSMC) will begin producing 4nm chips as soon as its new $12 billion plant in Arizona opens in 2024, Bloomberg reported, citing sources familiar with the matter.

The plant had originally planned to start with the production of 5nm chips, but with Apple and other companies increasingly looking to source components from the US, TSMC has upgraded its plans so the facility will be able to supply more cutting-edge chips.

Previously, TSMC, the world's largest contract chipmaker, said it would make 20,000 wafers per month at the Arizona facility, although production may increase from those original plans, the source said. Apple will use about a third of the output as production gets underway.

Bloomberg report says that Apple CEO Tim Cook will attend a ceremony on Tuesday, making things official.

Besides Apple, TSMC customers including Advanced Micro Devices and Nvidia have also reportedly asked TSMC to make more sophisticated chips at the Arizona plant.

In addition to the 4nm production facility, TSMC will reportedly announce plans for a second phase involving an adjacent facility that will produce even more advanced 3nm chips, a development that TSMC founder Morris Chang revealed last week.

Back in 2020, TSMC announced that it would be building a $12 billion chipmaking plant in Arizona. The construction of the main chip facility was completed in August.
