The four-layer diode was the key to William Shockley's plan to revolutionize AT&T's phone system. It was a great device in theory, but not in practice -- at least not at the time when Shockley ...

and some FETs even have ESD protection diodes built in, wired between gate and source. Unlike with BJT transistors that need a constant current flow, you only need to charge a gate once for the ...
