So What Was the Transistor Good For? Transistors may have been useful to the phone company and to a handful of scientists building computers, but that wasn't enough to build an industry.

Core MOSFETs are developed from planar transistors and FinFETs to the latest Stacked NanoSheet/NanoWire Gate-All-Around FETs (GAAFETs), and now to the cutting-edge vertical transistor 3D stacking ...
