TSMC is sending an envoy to Cupertino to discuss more details of manufacturing Apple A6 chips, insiders revealed late Wednesday. The talks, which Digitimes claims are to pledge "full support," should talk about 28 nanometer chip manufacturing yields as well as patent terms. Global UniChip, which is working with TSMC and has rights to use ARM's Cortex CPU and Mali graphics, is also believed to be part of the visit.
