Introduction
Polycrystalline silicon wafer is a form of elemental silicon. When molten elemental silicon solidifies under supercooled conditions, silicon atoms are arranged in the form of diamond lattice into many crystal nuclei. If these crystal nuclei grow into grains with different crystal orientations, these grains combine to form polycrystalline silicon.
