Abstract:
A bonded structure, comprising:an integrated circuit element having a number of conductive bonding pads;a first dielectric layer formed of first dielectric material;a lead array having a number of conductive leads formed on said first dielectric layer wherein each said conductive lead has an inner lead end and an outer lead end;a number of bonding pairs wherein each said bonding pair comprises one of said inner lead ends and one of said conductive bonding pads;an anisotropic conductive film having conductive particles dispersed in an insulating adhesive disposed so that a number of said conductive particles are between said inner lead end and said conductive bonding pad of each said bonding pair; anda number of electrical bonds wherein said inner lead end of each said bonding pair, said conductive bonding pad of each said bonding pair, and those said conductive particles between said inner lead end and said conductive bonding pad of each said bonding pair form electrical contact.
