Apple's iPhone fingerprint sensor supplier TSMC is preparing to begin production on sensors for the iPhone 6 in the second quarter of this year, according to a report from Digitimes. The report claims that TSMC will be shifting to a larger 12-inch fab from the current 8-inch fab, a move that should increase production efficiency. TSMC will also handle the packaging process for the sensors itself rather than contracting out to other firms, centralizing control over the component.Taiwan Semiconductor Manufacturing Company (TSMC) reportedly will begin producing fingerprint sensors for Apple's next-generation iPhone at its 12-inch fab using a 65nm process in the second quarter of 2014, according to industry sources.
