Patent ID: 7196363

Claim:
An integrated circuit, comprising: first and second layers; a first power supply conductor disposed in the first layer and coupled to carry a first supply voltage; a second power supply conductor disposed in the first layer and coupled to carry a second supply voltage; a third power supply conductor disposed in the second layer, overlapping the first power supply conductor, and coupled to carry the second supply voltage; a fourth power supply conductor disposed in the second layer, overlapping the second power supply conductor, and coupled to carry the first supply voltage; third and fourth layers; a fifth power supply conductor disposed in the third layer, overlapping the third power supply conductor, and coupled to carry the first supply voltage; a sixth power supply conductor disposed in the third layer, overlapping the fourth power supply conductor, and coupled to carry the second supply voltage; a seventh power supply conductor disposed in the fourth layer, overlapping the fifth power supply conductor, and coupled to carry the second supply voltage; an eighth power supply conductor disposed in the fourth layer, overlapping the sixth power supply conductor, and coupled to carry the first supply voltage; wherein the first power supply conductor has an edge adjacent to the second power supply conductor; wherein the second power supply conductor has an edge opposite the first power supply conductor; wherein the third power supply conductor has an edge opposite the fourth power supply conductor; wherein the fourth power supply conductor has an edge adjacent to the third power supply conductor; wherein the fifth power supply conductor has an edge adjacent to the sixth power supply conductor; wherein the sixth power supply conductor has an edge opposite the fifth power supply conductor; wherein the seventh power supply conductor has an edge opposite the eighth power supply conductor; wherein the eighth power supply conductor has an edge adjacent to the seventh power supply conductor; a first conductive via that electrically couples the edge of the first power supply conductor to the edges of the fourth, fifth, and eighth power supply conductors; a second conductive via that electrically couples the edge of the third power supply conductor to the edge of the seventh power supply conductor; and a third conductive via that electrically couples the edge of the second power supply conductor to the edge of the sixth power supply conductor.
