My understanding is that the active gate region is far smaller already so there is less room to scale than you might think.

- thechao 9y agoThe active region is smaller, but this is an argument about total bulk. IBM has shown functioning transistors with only a handful of atoms, already.
- xenadu02 9y agoYes, but that's the limit. Quantum effects mean we'll probably never see a single-atom transistor. Even if we did that's only a few more scalings. The rest of the features won't shrink as much anyway. We can see the end of the road. AFAIK no one has any clue how to even start thinking about 2nm or beyond. No one is even certain we will hit 5nm.
