Silicon and germanium have been the overall main materials, up until the last decade or so. Increasingly now you have other compounds being used such as SiC,AlP,AlAs,GaN,GaP,GaAs,GaSb,InP,InAs,InSb,ZnS,ZnSe,ZnTe,CdS,CdSe,CdTe,PbS,PbSe, and PbTe, as well as numerous 3-element combinations.Of course, SiO2 is still used to create windows for etching and as material for MOSFET gate dielectrics.Ag and Au are used for as contact materials.
