A structure having improved electromigration resistance includes a bulk interconnect having a dual layer cap and a dielectric capping layer. The dual layer cap includes a bottom metallic portion and a top metal oxide portion. Preferably the metal oxide portion is MnO or MnSiO and the metallic portion is Mn or CuMn.
