One process for forming crystalline wafers is known as Czochralski growth invented by the Polish chemist Jan Czochralski. In this process, a cylindrical ingot of high purity mono crystalline semiconductor, such as silicon or germanium, called a boule, is formed by pulling a seed crystal from a ' melt '.he boule is then sliced with a wafer saw (wire saw) and polished to form wafers. The size of wafers for photovoltaics is 100â200 mm square and the thickness is 200â300 Î¼m. In the future, 160 Î¼m will be the standard. Electronics use wafer sizes from 100â450 mm diameter.
