Abstract
A semiconductor device having a planar integrated circuit interconnect and process of fabrication. The planar integrated circuit comprises a substrate having a first line wire formed in the substrate, a dielectric layer formed on the substrate, a second line wire formed in the dielectric layer, a contact via formed within the dielectric layer extending through the dielectric layer from the second line wire to the first line wire, and a dummy via which extends into the dielectric layer and is filled with a low dielectric material.
