Abstract: PURPOSE:To make gate oxide films have resistance to oxidation, and to prevent the film thickness from changing even if exposed to thermal oxidation afterward, by nitriding the gate oxide films by heat treatment in a nitrogen gas atmosphere or an ammonia gas atmosphere after the formation of the gate oxide films. CONSTITUTION:An element isolation region having an element isolation insulating film 2 and an element region having the first oxide film 3 are formed on one conductivity type semiconductor substrate 1. A film having a thickness of about 100Angstrom -500Angstrom  is formed by thermal oxidation as the first oxide film 3, and heat treatment is performed in a nitrogen gas atmosphere or an ammonia gas atmosphere and the whole surface is nitrided. After that, thermal oxidation is performed to uniformize the film quality, the first oxide film 6 selectively nitrided using photoresist 4 is removed by using hydrofluoric acid, for example, and the second oxide film 5 is formed by thermal oxidation. This reduces the dispersion of the film thicknesses.
