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.
