The wafer serves as the substrate for microelectronic devices built in and over the wafer and undergoes many microfabrication process steps such as doping or ion implantation, etching, deposition of various materials, and photolithographic patterning.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.
