Why is smasung shifting to gate-last for 28nm, will it give any extra advantage or its not possible with gate-first approach ? . And if smasung shifts to gate-last approach is it big blow to IBM which is embracing gate-first technology ?

The gate-first approach makes it hard to control the transistor threshold voltage especially for p-channel devices. Only by exposing the metal gates to low process temperature (gate-last) can one control both the p-channel and n-channel device threshold voltages at the tight levels required for such advanced technology.

I wonder if they have "discovered" something about gate-first, high-k technology. If Intel is shipping the gate-last, high-k technology it must be a viable technology. What would make Samsung switch? Is there more to this story than meets the eye?
