Introduction to semiconductor material knowledge

Silicon is the most common semiconductor material, which has the advantages of good stability, low cost and mature processing technology. Silicon materials can be made into monocrystalline silicon, polysilicon, amorphous silicon and other forms, of which monocrystalline silicon is the most widely used in the manufacture of integrated circuits. The main disadvantage of silicon materials is that they are poor in electrical conductivity and need to be doped with other elements to improve their electrical conductivity.

Gallium nitride (GaN)

Gallium nitride is a new semiconductor material with high electron mobility, high conductivity and high thermal stability. Gallium nitride can be used to manufacture high-efficiency leds and high-power semiconductor devices. In addition, gallium nitride can also be used in aerospace, defense, communications and other fields.

Third, silicon carbide (SiC)
