Patent ID: 11227836

Abstract:
Various embodiments of the present application are directed towards a pad with high strength and bondability. In some embodiments, an integrated chip comprises a substrate, an interconnect structure, a pad, and a conductive structure. The interconnect structure adjoins the substrate and comprises wires and vias. The wires and the vias are stacked between the pad and the substrate. The conductive structure (e.g., a wire bond) extends through the substrate to the pad. By arranging the wires and the vias between the pad and the substrate, the pad may be inset into a passivation layer of the interconnect structure and the passivation layer may absorb stress on the pad. Further, the pad may contact the wires and the vias at a top wire level. A thickness of the top wire level may exceed a thickness of other wire levels, whereby the top wire level may be more tolerant to stress.
