Explanation: Silicon is abundantly available in the form of sand. It is possible to form superior stable SiO2(Which has superb insulating property). Whereas GaAs is more difficult to grow in crystal form and Ge crystal will be destroyed at high temperature. 9. What will be the next step after slicing (process) silicon wafers?
