Claim:
1. An electrical device comprising: an opening in a dielectric material; a metal including structure present within the opening for transmitting electrical current; and a liner between the dielectric material and the metal including structure, the liner comprising a superlattice structure comprised of a repeating sequence of a metal oxide layer, a metal layer present on the metal oxide layer, and a metal nitride layer that is present on the metal layer, wherein a first layer of the superlattice structure that is in direct contact with the dielectric material is one of said metal oxide layers, a final layer of the superlattice structure that is in direct contact with the copper including structure is one of said metal nitride layers, and at least one of the metal oxide layer, the metal layer and the metal nitride layer comprise manganese (Mn).
