I remember reading that at 5nm, electron tunnelling through transistor gates would be a major problem. What happened to that?

- ace2358 5y agoI think the do funky stuff with the 3D or 2.5D geometry of the gate so that the surface area (between transistors) is larger for a smaller footprint. Someone correct me if I’m wrong!
- jagger27 5y agoYes, that tech is called FinFET and it has been in use for many years. The new hot thing is GAAFET (Gate-all-around FET).
- aunty_helen 5y ago5nm doesn’t mean anything is actually 5nm. It’s the “5nm node” Marketing dept has trumped physics.
- imtringued 5y agoThat would be the case if 5nm didn't refer to a random feature of a reference planar transistor that is only used to chronologically name the process according to its mathematically equivalent density..
