Abstract
A method for producing interconnects on a workpiece includes obtaining a workpiece substrate having a feature, depositing a conductive layer in the feature, to partially or fully fill the feature, depositing a copper fill to completely fill the feature if the feature is partially filled by the conductive layer, applying a copper overburden, thermally treating the workpiece, and removing the overburden to expose the substrate and the metalized feature.
