Silicon wafers are generally not 100% pure silicon, but are instead formed with an initial impurity doping concentration between 10 13 and 10 16 atoms per cm 3 of boron, phosphorus, arsenic, or antimony which is added to the melt and defines the wafer as either bulk n-type or p-type.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.
