Abstract
A patterned conductive article includes a substrate having a first groove therein; a conductive seed layer disposed in the first groove; and a unitary conductive body disposed at least partially in the first groove. The conductive seed layer covers at least a majority of a bottom surface of the first groove, and the unitary conductive body covers the conductive seed layer and at least a majority of side surfaces of the first groove. In a plane through the unitary conductive body that is parallel to and separate from the conductive seed layer, the unitary conductive body has a lower first line edge roughness at a first interface with the side surfaces and the conductive seed layer has a higher second line edge roughness at an edge of the conductive seed layer.
