Abstract:
A semiconductor device comprising:a semiconductor chip having a pad-mounting surface that is provided with at least a bonding pad thereon; a plurality of supporting pads formed on said pad-mounting surface; a chip-mounting substrate attached to said semiconductor chip and having a chip-mounting surface that is formed with at least a conductive contact; and at least a conductive bump which is formed on one of said bonding pad and said conductive contact, said conductive bump including a hardened photoresist layer that is formed on said one of said bonding pad and said conductive contact and that has a geometric dimension smaller than that of said bonding pad so as to expose a portion of said one of said bonding pad and said conductive contact therefrom, said conductive bump further including a conductive layer enclosing said hardened photoresist layer and covering said portion of said one of said bonding pad and said conductive contact; said chip-mounting substrate being attached to said semiconductor chip in a manner that the other one of said bonding pad and said conductive contact is electrically connected to said conductive layer of said conductive bump and that said supporting pads interconnect said chip-mounting surface of said chip-mounting substrate and said pad-mounting surface of said semiconductor chip.
