Silicon (Si) is better than GaAs for three main reasons.
First, silicon (Si) processes are mass-produced and inexpensive processes. And silicon (Si) has better physical stress, so it can be made into large size
wafers
silicate
The second major advantage is that silicon (Si) can easily become
silicon dioxide
insulator
The third and perhaps most important advantage is that silicon (Si) has a much higher number of
holes

The raw material is silicon.
Silicon is the most important raw material in the production of integrated circuits, and the silicon wafer market accounts for about one-third of the entire semiconductor materials market. At present, more than 90% of integrated circuit chips are manufactured with silicon as the substrate, and silicon is the bearing basis of integrated circuits.
