Apple has become for TSMC 's largest customer , which will inevitably affect the performance of other customers' orders. In particular, TSMC recommended to place orders well in advance to prevent excessive loading of factory capacity in peak periods.
Apple is able to influence not only on the structure of TSMC production , but also on the schedule of the development of advanced technological standards. Taiwanese contractor has repeatedly stated its readiness to begin production of semiconductor products with topological 16 nm in the second quarter of 2015, but the timing of the start of mass production moved to the first quarter. As noted, TSMC monthly will process 50,000 wafers to 16-nm technology to fulfill orders for processors Apple A9.
Also, TSMC actively makes competition with Samsung company.
