ABSTRACT:
A semiconductor device is disclosed which comprises a semiconductor substrate and an insulating film disposed on the substrate. The insulating film is a oxynitride film prepared by nitriding a thermal oxide film, which has been formed on the substrate, in an atmosphere of nitriding gas. The nitriding is conducted for a nitridation time of 10.sup.6.6-T.sbsb.N.sup./225 seconds or shorter wherein T.sub.N is the nitridation temperature in degree centigrade, or conducted so as to have a nitrogen concentration of about 8 atomic % or less, at least in the vicinity of the interface between the nitride oxynitride film and the substrate. Also disclosed is a method for the production of the semiconductor device.
