Abstract

The chemical structures of thermal oxides were found to be affected strongly by the condition of silicon wafer in-situ cleaning. Based on this phenomena, the optimum condition for In the case of heating native oxides at 900°C the optimum condition for obtaining smooth and clean surface could not be found. The minimum amount of suboxides were found in thermal oxides when the native oxides formed in a solution with composition of HCl:H₂O₂:H₂O=1:1:1 maintained at 90°C were decomposed at 850°C.
