Apple's "A13" processor will use a 7-nanometer process for its production, but chip foundry TSMC is reportedly planning to use a different enhanced process to the current version it has come up with, named "N7 Pro."
TSMC's use of a 7-nanometer process for the next generation of Apple system-on-chips is not unexpected, with TSMC widely believed to not only continue to be the only supplier of A-series chips in 2019, but also keeping to the same process level. According to one report, TSMC will be making some changes to the process.
The Chinese Commercial Times claims TSMC will move to a 7-nanometer extreme ultraviolet lithography (EUV) process that has the potential for more accurate chip production and more intricate designs, named "N7+." HiSilicon's Kirin 985 chips will be the first to use N7+ in its production, but the Apple-designed "A13" will be the next to go into manufacturing at the firm.
For the A-series chip, TSMC will be bringing out an alternate form of its N7+ process which it calls "N7 Pro." It is unclear exactly what the difference is between N7 Pro and N7+, but it will reportedly be ready for volume production late in the second quarter, in time for A-series production for the fall iPhone refresh.
