Abstract
A method of forming a semiconductor device with a metal pillar overlapping a first top metal interconnect and a second top metal interconnect is disclosed. The metal pillar overlapping the first top metal interconnect and second top metal interconnect is connected to the first top metal interconnect by top metal vias while the second top metal interconnect does not contain top metal vias and remains free of a direct electrical connection to the metal pillar. The metal pillars are attached directly to top metal vias without a bond pad of metal. The elimination of the bond pad layer reduces the mask count, processing, and cost of the device. In addition, the elimination of the bond pad results in reduced die area requirements for the metal pillar.
