Abstract
A method includes forming a first conductive feature positioned in a first dielectric layer. A conductive polymer layer is formed above the first dielectric layer and the first conductive feature. The conductive polymer layer has a conductive path length. A second dielectric layer is formed above the first dielectric layer. A first via opening is formed in the second dielectric layer and the conductive polymer layer to expose the first conductive feature. A conductive via is formed in the first via opening. The conductive via contacts the first conductive feature and the conductive polymer layer.
