Patterned conductive article

A patterned conductive article comprising:

• a substrate comprising a first groove therein, the first groove having a bottom surface and side surfaces;
• a conductive seed layer disposed in the first groove;
• and
• a unitary conductive body disposed at least partially in the first groove,
• wherein the conductive seed layer covers at least a majority of the bottom surface of the first groove, and the unitary conductive body covers the conductive seed layer and at least a majority of the side surfaces of the first groove, and wherein 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 first line edge roughness at a first interface with the side surfaces, and the conductive seed layer has a second line edge roughness at an edge of the conductive seed layer, the conductive seed layer defining therein a plurality of fractures extending from an edge of the conductive seed layer to an interior region of the conductive seed layer, the fractures causing the second line edge roughness to be greater than the first line edge roughness.
