I have the utmost respect for TSMC. For their advanced technology; for the quality of their products; for their ecosystem; and for their contribution to the industry. In fact, TSMC has become so big – that it will take a while until the second ranked foundry can catch up.
The deep sub-micron technology, particularly 28nm and below, has made the foundry business a game of investment, allocation and cash flow. Don’t get me wrong, the semiconductor business is still about technology innovation, but in today’s consumer market a shortage in 28nm wafer supply means less tablets and diminished phone production. Can the economy afford that?
