Abstract
A method of manufacturing a semiconductor device is set forth comprising a semiconductor body (1) having a surface (2) adjoined by a semiconductor region (3) and a field oxide region (4) surrounding this region, on which surface (2) is provided a metal layer (13), in which a conductor track (17, 18) is formed, after which an isolating layer of silicon oxide (19) is deposited over the conductor track (17, 18) on the surface (2). According to the invention, before the layer of silicon oxide (19) is provided over the conductor track (17, 18), this track is provided with a top layer (16) of an oxidation-preventing material. By providing this top layer (16), it is avoided that the conductor track (17, 18) covered by silicon oxide (19) has a high electrical resistance or even an electrical interruption.
