Abstract: Methods of depositing an oxygen deficient metal film by chemical reaction of at least one precursor having a predetermined oxygen deficiency on a substrate. An exemplary method includes, during a metal oxide deposition cycle, exposing the substrate to a metal reactant gas comprising a metal and an oxygen reactant gas comprising oxygen to form a layer containing a metal oxide on the substrate. During an oxygen deficient deposition cycle, exposing the substrate to a metal reactant gas comprising a metal and an additional reactant gas excluding oxygen to form a second layer at least one of a metal nitride and a mixed metal on the substrate during a second cycle, the second layer being oxygen deficient relative to the layer containing the metal oxide; and repeating the metal oxide deposition cycle and the oxygen deficient deposition cycle to form the oxygen deficient film having the predetermined oxygen deficiency.
