TSMC needs to improve yield rates on 10nm first
The folks at Boston-based BlueFin Research Partners have recently given some much-needed commentary on the state of 10nm chip production at TSMC for Apple’s next-generation iPhone units.
For the past three years, production of TSMC’s leading-edge process nodes - 20nm, 16nm and 16FF+ - has always ramped up following orders of a new iPhone SoC – the Apple A8, A9 and A10. In 2017, it appears this will not be the case as the researchers claim that TSMC’s 10nm yields are currently still below 50 percent.
