Abstract:
A structure for improving the firmness of bond wires, comprising:a composition layer formed on an insulator layer to serve as a part of a multi-level interconnection, said composition layer being composed with at least one conductive layer and at least one dielectric layer thereon, said conductive layer of said composition layer including a regular or an irregular layout pattern to obtain a rough upper surface of said dielectric layer; a bond pad conductive layer formed on said dielectric layer of said composition layer, and said bond pad conductive layer serves as a bond pad region; a passivation layer formed on said bond pad conductive layer; a plurality of bond pad windows in said passivation layer to expose said bond pad conductive layer; and a plurality of bond wires formed in said bond pad windows to couple to an external circuit.
