Interconnect structures including liner layers that are non-planar with at least the adjacent insulating layer and at least one capping layer on conductive features embedded in the insulating layer. The interconnect structure includes an insulating layer of a dielectric material having a top surface and a bottom surface between the top surface and a substrate. An opening, such as a trench, has sidewalls extending from the top surface of the insulating layer toward the bottom surface and is at least partially filled by a conductive feature. A capping layer is disposed on at least a top surfaceof the conductive feature. A conductive liner layer is disposed between the insulating layer and the conductive feature along at least the sidewalls of the opening. The conductive liner layer has sidewall portions projecting above the top surface of the insulating layer adjacent to the sidewalls of the opening.
