I 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!

Yes, that tech is called FinFET and it has been in use for many years. The new hot thing is GAAFET (Gate-all-around FET).
