Abstract:
1. A semiconductor device comprising: a semiconductor die having at least one electrode disposed on a major surface thereof; a passivation layer disposed over said at least one electrode of said semiconductor die; an opening in said passivation layer extending from the top surface of said passivation layer to said at least one electrode; and a preform non-spherical copper electrical connector including a base portion having a selectable shape and a contact portion for making electrical contact with an external element; wherein said base portion of said electrical connector is electrically and mechanically connected to said at least one electrode of said semiconductor die by a layer of conductive adhesive material disposed within said opening, said conductive adhesive material being either solder or conductive epoxy, and wherein said shape of said base portion is configured to maximize the area of said passivation, and said opening is selectable to correspond to said shape of said base portion.
