Claim 9:
10. A semiconductor chip package comprising:
a package substrate including a bond pad; and
a semiconductor chip mounted on the package substrate, the semiconductor chip including:
a device layer;
an interconnect layer fabricated on the device layer, the interconnect layer including a conductive pad disposed on a final dielectric layer of the interconnect layer; and
a conductive pillar interconnecting the conductive pad and the bond pad of the package substrate, the conductive pillar including at least a first portion having a first width and a second portion having a second width, the first portion being disposed between the second portion and the conductive pad, the second portion being disposed between the first portion and the package substrate, wherein the first width of the first portion is greater than the second width of the second portion.
