According to this invention, a method for fabricating a semiconductor element comprises the steps of: providing a semiconductor wafer; forming an oxide layer on the semiconductor wafer; carrying out a high-temperature thermal treatment to the semiconductor wafer at least once, wherein the high-temperature thermal treatment comprises a final high-temperature treatment, which is carried out lastly as the high-temperature thermal treatment; lowering a temperature of the semiconductor wafer, following the final high-temperature treatment, to a predetermined lower temperature; and exposing the semiconductor wafer in an oxidizing atmosphere after the temperature lowering process.
