Abstract:
A semiconductor device assembly 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 device having an active surface having at least one bond pad thereon; and a non-conductive polymer adhesive comprising a copolymer material selected from a group of isobutyl compounds, a first portion of said non-conductive polymer adhesive including isobutyl acetal diphenol copolymer, said non-conductive polymer adhesive being characteristically tacky and compliant at a room temperature in a range of about 50Â° F. to 95Â° F., said non-conductive 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 device for compression therebetween to connect said at least one bond pad of said semiconductor device to said at least one lead finger of said plurality of lead fingers of said lead frame.
