Methods for forming interconnect or interconnections on a substrate for use in a microelectric device are disclosed. In one or more embodiments, the method includes depositing an alloy layer comprising Cu and an alloying element, for, example, Mn, in a dielectric layer and segregating or diffusing the alloying element from the bulk Cu portion of the alloy layer. In one or more embodiments, the method includes annealing the alloy layer in an atomic hydrogen atmosphere. After annealing, the alloy layer exhibits a resistivity that is substantially equivalent to the resistivity of a pure Cu layer.
