Avoid voltage loss and protect FETs from static energy
Old fashioned p-n junction devices suffered from a voltage drop (0.6V for Si, 0.2V for Ge, if I remember correctly).

FETs and CMOS were the latest highlight back then, and highly prone to be destructed from static electricity ("don't touch with your fingers").

That does not look like a problem nowadays.

How is that achieved?
