Filed: 1989-05-29
Abstract: PURPOSE:To facilitate normal patterning of an electrode by a method wherein a silicate glass film is formed on a semiconductor substrate having an uneven surface and, after a thermal treatment, a multilayer wiring composed of an aluminum film, a vanadium film and an aluminum film is formed on the silicate glass film. CONSTITUTION:A wire 110 made of Cu is bonded to a three-layer electrode. Even if a wire giving a high impact such as a Cu wire 110 is bonded, if a vanadium film 108 is provided between a first Al film 107 and a second Al film 109, the impact given by the Cu wire is relieved by the vanadium film 108, so that a damage given to the surface of a semiconductor substrate 101 can be relieved. Moreover, the vanadium film 108 prevents the Cu wire 110 from digging itself into the electrode. Further, even if the unevenness of the surface formed by patterning is sharp, if a BPSG film 105 is provided on the uneven surface, the BPSG film 105 can be melted by a thermal treatment and the step parts of the uneven surface can be smoothened. Therefore, even if the steps of the uneven surface are sharp, the electrode can be patterned normally.
