Well, before we know the semiconductor chemicals ,let’s first took a look at the semiconductor materials. The semiconductor materials is kind of electronic materials with semiconductor properties.
And generally, the conductivity is between conductors and insulator. Since the materials’ resistivity is about 1mΩ·cm～1G, and they are usually the material for the semiconductor devices as well as the integrated circuits.
The semiconductor materials are usually single crystal material, and it is not good as the gallium arsenide. And the electric chemicals can help to get more purer crystal materials and improve the performance.
