Abstract: PURPOSE:To suppress the growth of bird's beaks by a method wherein the thickness of an initial film formed in a semiconductor substrate is reduced to a limit of processing and a selectively oxidized thin mask and a stopper layer whose thicknesses are equivalent to the thickness of the initial film and a selectively oxidized thick mask are formed on the initial film. CONSTITUTION:An initial oxide film 2 of 100 Angstrom  thickness is formed on a semiconductor silicon substrate l under the oxidation conditions wherein the temperature is 1000.C and the atmosphere is the air containing HCl. Then a CVD silicon nitride film 11 is formed to have a thickness of 200 Angstrom . Further, after a CVD silicon oxide film 12 is formed to have a thickness of 200 Angstrom , a CVD silicon nitride film 15 is formed to have a thickness of 1500 Angstrom  and, after resist patterning, the films 11, 12 and 13 are etched. Then, after the resist is removed, field oxidation is carried out to form a field oxide film of 7000 Angstrom  thickness, With this constitution, the size of the formed bird's beak is 0.15-0.2 mum. Therefore, the size of the bird's beak is suppressed so that the high integrity of a semiconductor device can be realized.
