TSMC's 28nm process builds the new Snapdragon S4 family of Qualcomm, that is in so many phones these days, but it can't even equip the factories with the high-precision machinery needed fast enough to satisfy demand this year. It recently even broke the 3GHz barrier with a 28nm mobile chip to showcase what the technology is capable of. Apple, on the other hand, has been trying to break away from Samsung as chip supplier, due to the legal spat between the two.
emergency exec meeting after the verdict that the foundry business in Austin, Texas, that makes chips for the iPhone and the iPad, is "firewalled" from the legal drama between the two companies, but you never know. Still, Samsung just last week announced another $4 billion will be poured in the Austin factory, so apparently it doesn't expect Apple to be able to shift chip production any time soon.Samsung has reportedly said at the
Back to TSMC, it is apparently afraid that if it dedicates a factory or two to one single client, it will have a hard time retooling it if a rapid shift in technology appears. We don't know what rapid shift will go against industry stalwarts like Apple and Qualcomm, but you never know what ARM is cooking up its sleeve for the next generation of mobile chipsets, so the Taiwanese are hedging their bets. “You have to be careful. Once that product migrates, what are going to do with that dedicated fab? We would like to keep the flexibility”, said TSMC's Chief Financial Officer Laura Ho.
