Abstract

PURPOSE: To obtain an isolating oxide film free from bird beaks by using a double film of an Si3N4 and an SiO2 film thicker than this as an etching mask in forming a dug portion within a substrate in order to deposit an oxide film for isolating discrete function elements of a semiconductor device.
