Abstract:
A process of producing a semiconductor device, comprising the steps of:coating a surface of a semiconductor substrate, provided with a pad for electrical connection, with a first insulating film having an opening to which the pad is exposed; modifying a surface of the first insulating film and an inner wall surface of the opening; forming, by an ion-exchange reaction, a thin conductive film with which the surface of the first insulating film, the inner-wall surface of the opening, and a surface of the pad exposed on a bottom surface of the opening is coated; thickening the thin conductive film by electroplating with power fed using the thin conductive film; forming a second insulating film with which the thickened conductive film is coated and having an opening to which a part of the conductive film is exposed; and forming a connecting member joined to the thickened conductive film inside the opening of the second insulating film.
