Abstract
PURPOSE:To form a wiring without difference in steps on a surface, by selectively etching a conductive layer including impurities, which is provided on a semiconductor substrate and withstands high temperature treatment, with an etching mask, and embedding an insulating layer having a specified thickness in an etched cavity. CONSTITUTION:In the application on a bipolar integrated circuit, a resist pattern 9 is formed on a nitride film 3 on an Si substrate 1. With the resist 9 as a mask, the Si3N4 film 3 is etched, and an etched groove having a rectangular cross section without an undercut is provided. Polycrystaline Si 2 including impurities is deposited on the groove at a low temperature, and the etched groove S is buried. At this time deposition is not made on a wall 9' of the resist. The resist 9 is removed, impurities including poly crystalline Si is thermally diffused, and an impurity diffused layer 6 is formed. Thus the wiring having a fine width can be formed without the difference in steps on the surface.
