Abstract

PURPOSE: To decrease defective layer caused on the substrate, by dividing the thermal oxidation into two times and by performing the oxidation with a temperature at the second greater at least by 50°C than the first oxidation temperature, in forming oxide film on a semiconductor substrate.
