Silicon wafer (single side polished), P-type, 3 inch diameter and 0.5 mm thickness
The silicon thermal dioxide wafer refers to the thermal growth of a uniform dielectric film on the surface of the silicon wafer, which is used as an insulation or mask material. The oxidation process includes high temperature dry oxygen oxidation and high temperature wet oxygen oxidation.
Growing a silicon ingot can take anywhere from one week to one month, depending on many factors, including size, quality and the specification. More than 75% of all single crystal silicon wafers grow via the Czochralski (CZ) method.
