Abstract: PURPOSE:To restrain a bird's beak from being expanded and to form a precise and flat element isolation region by a method wherein a field oxide film which has been formed to be thinner than a prescribed thickness is formed to be a prescribed thickness in the thermal oxidation process of an inner wall surface of an element isolation groove and a mask for field oxidation is left even after a selective oxidation operation. CONSTITUTION:A thin field oxide film 4 and an element isolation groove 5 are first formed. After that, a thermal oxidation operation is performed by utilizing a mask 3, for oxidation, which has been used at the beginning as it is, the field oxide film 4 is made thick and, at the same time, an inner wall on the element isolation groove 5 is oxidized thermally. This contributes to the increase in a film thickness in the selective oxidation process of the field oxide film 4. As a result, the field oxide film 4 becomes the same shape, including a bird's beak, as an ordinary field oxide film 4 formed by a selective oxidation operation as long as the film thickness of a final field oxide film 4 is the same. As a result, the shape of the bird's beak is not affected by the oxidation process of the inner wall on the element isolation groove 5.
