The inside of the chip is semiconductor material, most of which is silicon material, and the capacitors, resistors, diodes, and transistors inside are made of semiconductors. A semiconductor is a material between a conductor like copper, which allows electricity to pass easily, and an insulator like rubber, which does not conduct current. A solid state electronic device composed mainly of amorphous semiconductor materials.
Although the amorphous semiconductor molecule is disordered on the whole, it still has the microstructure of a single crystal, so it has many special properties.
