  • Patent number: 6867070
    Abstract: A bonding pad structure in an integrated circuit (IC) and a method for manufacturing thereof comprises a plurality of dummy patterns deposited in sub-layers of the IC, each dummy pattern being connected via a metal link to a plurality of complementary top surface bonding pads, wherein the dummy patterns and the metal link are constructed during the same process steps used to construct the circuit elements included in the IC, without additional or special process steps. Such an imbedded and anchored bonding pad provides contact reliability for both conductive and non-conductive pads used for the interconnection of integrated circuits in a manner that resists layer separation or de-lamination under pulling stresses that are present on the bonding pads.
