2. Oxidation Methods
Dry oxidation and wet oxidation are the most important methods for growing silicon on oxide wafer.
2.1 Dry oxidation silicon wafer
Dry oxygen oxidation silicon reacts with oxygen at the temperature of 850-1200 ℃, the rate of thermal oxide growth silicon wafers is low but the quality is good, so it can be used for MOS insulated gate growth. Silicon wafer oxide thickness is 10nm~300nm.
2.2 Wet oxygen oxidation wafer
At high temperature, water vapor is used to enter the furnace tube and form oxide layer on the surface of silicon wafer. The density of wet oxygen oxidation is slightly worse than that of dry oxygen oxidation, but the advantage of wet oxygen oxidation is that it has a higher growth rate, which is suitable for the film growth above 500 nm. Wet oxidation capacity: 100nm~6um.
During the silicon wafer oxidation process, the thermal silicon oxide wafer is an excellent dielectric layer as an insulator. In many silicon-based devices, the thermal oxide layer plays an important role as a doping prevention layer and a surface dielectric.
