I would say Intel have shown the manufacturability of gate last! In terms of pure transistor performance, gate last is the winner for PMOS because it gets extra strain into the channel, and that is likely the case for NMOS at the 2x node too.

When it is Intel, TSMC v.s. AMD, Globalfoundries, and Samsung, it is interesting just for "bragging rights" only. For companies like AMD, Altera, Xilinks, Altera, nVidia, and Qualcomm, they should care becase they rely on the leading edge technologies from the foundries. When IBM claims the performance advantage of "gate-first", manufacturability and cost are probably more important concerns. Who knows Intel and TSMC will not switch to gate-first in the future nodes?

Kris, like I said, ask Apple, Nokia, Moto, Dell, etc. They care about litho, scaling, gate stacks, DFM, etc.. They want to know how we will get to 20-nm and beyond.

thank you Mark, perhaps I didn't myself clear...of course we need process scaling for next-gen electronics...what I said is that not too many people care whether you put gate first or at the end of CMOS processing (this was a theme of the article), do you? Kris

I disagree with you Kris. It is critical that chip makers can scale the gate, so we (you and I) can buy next-generation phones, PCs and tablets. It is interesting to know just how chip makers can scale the gate dielectric. I will bet Apple cares. So does Qualcomm. Want more examples?

Interesting development for sure but does anyone care (beyond people at IBM and Applied Materials)? Kris

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
