It looks like TSMC will help manufacture Apple’s A9 chips after all

Facing poor yield rates from chipmaker GlobalFoundries, Apple has apparently made an eleventh-hour call as it solidifies its supply chain for the next-generation iPhone, opting to award nearly a third of “A9” chip orders to Taiwan Semiconductor Manufacturing Co. Well-connected analyst Ming-Chi Kuo of KGI Securities issued a note to investors on Wednesday, a copy of which was obtained by AppleInsider, revealing that Apple has apparently made what he called a “last-minute decision to recruit TSMC.” Apple is said to have called an audible after partner GlobalFoundries continued to experience poor yield rates on production of the next-generation CPU. Specifically, GlobalFoundries’ “A9” chip yield rate is said to currently be at about 30 percent yield rate, which is well below what Kuo said is a mass-production “basic requirement” of 50 percent. “Recruiting TSMC reduces supply uncertainties for Apple,” the analyst said.
