Why is silicon 'the choice' for ICs? I am aware that materials such as GaAs and GaN are used in MMICs where high frequencies are involved. So why is silicon still the major material used in all ICs?...

To add to these most important reasons, Si provides very high substrate resistivity, it is one of the elementary semiconductor material and crystalline Si is easy to achieve from it's natural resources.

Silicon is so cheap and abundant as a raw material, but requires many processes, probably more than fabricating a GaAs IC. How approximately how much is it to fabricate a silicon chip?

readily available as a raw material and even though is forward voltage is .7 (for Ge its is .3)its leakage current is low when compared with Ge that why its widely used
Hi All!
don't relate cost etc.,
Silicon has physical and electrically best quality native oxide compared to other semiconductor materilas.
does it make sense
