Silicon wafer: the sheet structure of single silicon material, with relatively thin thickness. There are mainly two kinds of structures, circular and square, including single crystal and polycrystalline. Single crystal is a kind of crystal material with fixed crystal orientation, which is generally used as the substrate of semiconductor integrated circuit and also used to make solar cell. Polycrystalline is a kind of crystal material without uniform fixed crystal orientation, which is generally used for solar photovoltaic power generation, or for the raw material of monocrystalline silicon. Monocrystalline silicon is a kind of excellent high-purity semiconductor material.
