A semiconductor device includes a substrate, and an interconnection layer on the substrate. The interconnection layer includes an interconnection structure having a first interconnection line therein that includes a metal alloy containing a single phase of ruthenium and a non-ruthenium first element having a concentration in a range from greater than 0 at % to 40 at % in the metal alloy. In the event the first element is molybdenum, the concentration of the first element in the metal alloy may range from 0.1 at % to 30 at %; but, in the event the first element is tungsten, the concentration of the first element in the metal alloy may range from 0.1 at % to 40 at %.
