Abstract:
A process of fabricating a semiconductor device which has a wiring layer and active elements on a semiconductor substrate, the wiring layer and the active elements being protected by a protective film, and is provided with a projected electrode for connection with the outside in an opening portion of the protective film on an Al electrode pad electrically connected to the wiring layer, which comprises the steps of:removing by sputtering a surface oxide film formed on a surface of the Al electrode pad;depositing a film of a first metal on the Al electrode pad by substituting the first metal with Al constituting the Al electrode pad; anddepositing a film of a second metal for constituting the projected electrode on the film of the first metal by substituting the first metal with the second metal, and forming the projected electrode by electroless plating by use of autocatalytic reaction.
