It depends on how one defines transistor but I believe there is no known fundamental limit. If transistor as switch is sufficient then single-atom transistors

It depends on how one defines transistor but I believe there is no known fundamental limit. If transistor as switch is sufficient then single-atom transistors have been demonstrated. https://en.wikipedia.org/wiki/Single-atom_transistor https://en.wikipedia.org/wiki/Single-atom_transistor
- RetroTechie 3y agoIn that (extreme) example, each transistor requiring at least 1 atom, would be your fundamental limit. New semiconductor materials or entirely different approaches (like quantum computing, optical ICs, 3D stacking etc) may give us a few more orders of magnitude. But as the article states: most likely it's economic barriers. Market conditions must support the technical effort required. Otherwise that tech is a dead end no matter how far it could go in theory. FWIW: in a way I'd welcome an end to Moore's law. It's about time software bloat gets addressed more aggressively.
