What kind material science improvement would make non-marketing, real ~10nm scales a reality? I literally have no idea how RnD works in this field. Is it trial and error? How do these scientists come up with ideas that increases the transistor density? Do our current gen CPUs have 2d or 3d curcuit layout? How one can learn about these stuff without working in the field?
- rusticpenn 7y agoThe biggest bottleneck is the laser (physics) used for etching of the layers ( and at some point, the number of electrons passing throught the gate, which intel solved using a "3D" gate.)

- diegoperini 7y agoWatched it, thanks a lot!
- marcosdumay 7y agoA less than 10nm transistor with the same design transistors had 20 years ago does basically not work (you can do some analog hackery, but it's does not behave like a transistor). Every semiconductor has a lower limit, for silicon it's ~10nm.
- brennanpeterson 7y agoGo through the lithoguru class notes on YouTube to learn. Some stuff. There are some nice talks from Kellin Kuhn or Dick James that have good detail. If.you are visual, Coventor has some nice visualizations. And I really like the work from Nikonov and Young. If you really.want to get into the ideas, the series.of.papers and notes on E-tau scaling rules are great. Maybe not complete, but good. Ideas for density aren't too hard: shrink pitch and fold into the z dimension. 3DNand is a folded NAND string, after all. On materials, it really is driven by etch and lithography (collectively, patterning). Mostly not materials themselves.
