Silicon oxide wafer A silicon dioxide layer is formed on the surface of the thermal oxide. In the presence of an oxidant at an elevated temperature, the process is called thermal oxidation. The thermal oxide layer is usually grown in a horizontal tube furnace. The temperature range is controlled at 900 to 1200 degrees Celsius, using wet or dry growth methods. Thermal oxide is a growing oxide layer. Compared with the oxide layer deposited by CVD method, it has higher uniformity and higher dielectric strength. This is a good dielectric layer as an insulator. In most silicon-based devices, the thermal oxide layer plays a very important role to comfort the surface of the silicon wafer. As a barrier to doping and surface dielectric.
