Classification: CPC H | IPC H

Claim 19:
20. The semiconductor device of claim 7, wherein the dielectric structure includes a first dielectric layer laterally surrounding the first and second metal vias and a second dielectric layer laterally surrounding the first and second metal lines, the first dielectric layer having a first composition and the second dielectric layer having a second composition that differs from the first composition; and further comprising:
a conductive via disposed in an upper portion of the first dielectric layer and contacting an upper portion of the first metal cap layer, the conductive via having outermost sidewalls spaced apart by a second distance less than the first distance; and
a conductive line disposed in the second dielectric layer and contacting an upper portion of the conductive via, the conductive line having outermost sidewalls spaced apart by a third distance, wherein the third distance is greater than the second distance and is greater than the first distance.
