How close are we to fabricating a Germanium IC? Ask Question 4 \\begingroup\ I am not actually talking here about SiGe(SiliconGermanium hybrids) but an integrated circuit that uses entirely Germanium(doped of course in certain areas)? It is my understanding that even though Germanium was used to make the first discrete transistors, there are ...

There are many semiconductor material but why silicon and ...

Silicon pretty much took over from germanium in the 1960s, when people figured out how to work with it. Silicon has one very big advantage compared to other semiconductors: it is easy to thermally oxidize, and the oxide coating that develops is an excellent insulator. This property of silicon is what allowed the development of integrated circuits.
