Intels Jim Keller says that if you think Moores Law is dead and you dont believe in it youre a little delusional. And to make sure that the technology world keeps kicking along with the pace it has done were all building nanowires in the fab.

This new design of transistor sees silicon moving beyond the 3D FinFET transistor design, which our graphics cards and CPUs have been running on since planar transistors died a death, and pushing into the Gate All Around (GAA) era. Weve heard about Samsungs plans for GAA design around the 3nm mark; its already given out the design kit for the upcoming process, making it sure look like Moores Law still has a few nodes left.

Keller has been giving his Moores Law Is Not Dead talk over at Berkeley this week, and the UC Berkeley EECS Events team has live streamed the entire thing over on YouTube and you can catch up on this fascinating, intimate little chat right now. And it basically boils down to a simple if youre not prepared to let Moores Law die then it wont.

We had planar transistors, we went to FinFET, says Keller. Were all building nanowires in the fab. Intel, TSMC, Samsung, everybodys working on it. Theres a really interesting thing while the world thinks Moores Laws dead, the fabs and the technologists think its not and everybodys announced now a 10-year roadmap for Moores Law.

Keller also goes on to describe tasking his engineers with finding a pathway to 100x gate density. They came back all glum because they could only come up to 50x right now, so thats what hes going with

Theyve got clear line of sight to pitch scaling of the eponymous fins of FinFet tech, delivering a 24nm fin pitch, which is about 3x. At this point Keller feels the need to explain that there are still shrinks that can be made, after all, the tip of the fins is still over 100 atoms wide.

So were not running out of atoms, he says. We know how to print single layers of atoms but the fins themselves, theyre mountains.

Then its on to nanowire technology, then stacked nanowire technology, and on to wafer-to-wafer stacking. After that its die-to-wafer stacking because, as Keller says, 3D stacking is going to become more and more important as we build stuff.

His point is that basically, Moores Law is not dead, because theres a whole bunch of people invested in making sure it doesnt happen. John Carmack sure as hell is a smart cookie, but hes not necessarily at the leading edge of semiconductor technology development.

If your idea set says this is going to keep going, and theres a whole bunch of challenges, then I think we will rise to the challenge, says Keller. And Ive seen that over and over. If you think its running out of gas, it will. If you think its not, its not going to. And theres many people in the industry working on this.

So many people have told me computer architecture cant move any further. Really? How many times has it changed over the last thirty years? Like, over and over and over.
