Taiwanese semiconductor manufacturer and Apple's chip partner TSMC will reportedly start volume production of A11 chips from April 2017, which will be supplied to the new-generation iPhones to be launched in September 2017.

The A11 chips will adopt the 10-nanometer FinFET manufacturing process. However, this is not TSMC's first 10-nanometer chip product. The company started using a 10-nanometer manufacturing process from late last year and it started supply the chips from the first quarter of 2017.

TSMC's production and supply planning of A11 chips is basically the same as those for iPhone 7. By the end of 2017, the company is expected to make 100 million A11 chips, which is a little bit higher than the supply of A10 Fusion chips. A10 Fusion chips are quad-core chips used on iPhone 7 products and it adopted a 16-nanometer process.

The new A11 chips will be used on iPhone 7s or iPhone 8. TSMC will start volume production of A11 chips from April 2017 and its shipment may reach 50 million units before July 2017.
