Chip raw materials are mainly monocrystalline silicon, the nature of silicon is to do semiconductor, high-purity monocrystalline silicon is an important semiconductor material. P-type silicon semiconductor is formed by adding a trace of Group IIIA element into monocrystal silicon. A small amount of group VA element is added to form an N-type semiconductor. The P-type semiconductor and the N-type semiconductor are combined to form a p-n junction, which can be made into a solar cell.

These doped chemical elements are also raw materials for making chips, forming different types of semiconductors to meet the needs of integrated circuit components, small but very important, such as gallium arsenide doping.
The raw material of the chip is mainly silicon, rare earth is also an important strategic metal resource for chip production, gallium nitride is a key material for the third generation of semiconductors, and silicon ingots are obtained after transverse cutting.
The first step in making a chip is to extract silicon from the sand, and the silicon atom has at most one impurity atom. Then the photolithographic material is injected with ions, the wafer can be polished and coated with photoresist, and finally the circuit layout of the chip is printed out
