Patent ID: 6979888

Claim:
A semiconductor device comprising: a lead frame having a plurality of lead fingers thereon, at least one lead finger of said plurality of lead fingers having an attaching surface; a semiconductor die having an active surface having at least one bond pad thereon configured for electrical connection to said at least one lead finger of said plurality of lead fingers of said lead frame; and a nonconductive polymer adhesive selected from a group of adhesives that is tacky and compliant at room temperature, said nonconductive polymer adhesive applied to one of said attaching surface of said at least one lead finger of said plurality of lead fingers of said lead frame and a portion of said active surface of said semiconductor die for compression therebetween to electrically connect said at least one bond pad of said semiconductor die to said at least one lead finger of said plurality of lead fingers of said lead frame, said nonconductive polymer adhesive including a first material from a group of copolymers that includes isobutyl compounds and a second material that is from a group of metal oxides.
