Abstract

PURPOSE:To keep the flatness, by providing a coating layer flatly on polycrystalline silicon which is filled in an isolating V groove; and performing plasma etching with a gas, wherein mixing ratio of gas of fluorine series and oxygen gas is adjusted and etching speeds are equal. CONSTITUTION:The V groove is formed in an epitaxial layer 2 provided on a silicon substrate 1 by using an SiO2 layer 3 and an Si3N4 layer 4. An SiO2 layer 3' is formed on the walls of the groove, and the polycrsystalline silicon 5 is filled in the groove. A resinous coating material layer 6 comprising polyimide resin and the like is provided on said silicon 5, and the surface of the layer 6 is made approximately flat. Plasma ethching is performed by a gas, wherein the mixing ratio of C2 F6 gas and O2 is adjusted and the etching speeds of the layers 5 and 6 become equal; thereby the polycrystalline silicon outside the groove is removed. In this method, the surface of the V groove is flattened by dry etching, and the intrusion of alkali metals and the like can be prevented.
