Apple reportedly used Taiwan Semiconductor Manufacturing Company (TSMC) to build 5G modems for future iPhones. It's not clear exactly when the new device will be ready for deployment, but we hear that in 2023 it will be based on TSMC's 4nm process.
Sources familiar with the matter told Nikkei Asia that Apple plans to use TSMC's 4nm manufacturing process for its first integrated 5G modem. They added that Apple is also working on radio frequency and millimeter wave components to complement the 5G modem, and others noted that the iPhone maker is also developing its own power management chip for the modem. p>
