A number of chip makers have already started stocking parts intended to be used in production of Apple's next-generation iPhone, according to industry sources for DigiTimes. Qualcomm and Broadcom are said to be producing 4G and Wi-Fi chips using a 28nm process at Taiwan Semiconductor Manufacturing Company. OmniVision is also said to be hunting for production at TSMC's 12-inch fab, contributing to limited production capacity. OmniVision specializes in camera components, and has supplied cameras for Apple handhelds in the past.
