Filed: 1989-05-24
Abstract: PURPOSE:To enable a polycrystalline silicon to be embedded into a recess and then achieve flattening without producing any stage difference by accumulating a semiconductor thin film with a film thickness which is 1/2 or more than the width of the recess and by performing oxidation so that no semiconductor thin film at an area outside the recess remains. CONSTITUTION:After eliminating a PSG film 4, the bottom part of an isolation groove 5 and a side surface part are oxidized for forming an oxide film 6, a high-concentration boron is ion-implanted into the bottom of the isolation groove 5, a channel stopper region 7 is formed at the bottom of the isolation groove 5, and then a polycrystalline silicon film 8 is accumulated by the film thickness which exceeds 1/2 of the width of the isolation groove 5. Then, after etching the polycrystalline silicon film 8 by a desired thickness so that it remains on the entire surface of substrate, the polycrystalline silicon film 8 is oxidized so that it does not remain outside the separation groove 5, thus forming an oxide film 10. Therefore, only the semiconductor thin film at a part to be eliminated other than the area within a recessed part can be changed to an oxide film and a semiconductor thin film can be embedded into the recessed part without sacrificing flattening properties.
