Abstract:
1. An atomic layer deposition method of forming a conductive metal nitride-comprising layer in the fabrication of integrated circuitry, comprising: providing a substrate within a deposition chamber; chemisorbing a first species to form a first species monolayer onto the substrate from a gaseous first precursor comprising at least one of an amido metal organic compound or an imido metal organic compound, the first species monolayer comprising organic groups; contacting the chemisorbed first species with a second precursor plasma effective to react with the first species monolayer to remove organic groups from the first species monolayer; the chemisorbing of the first species being void of plasma, and further comprising feeding both of the first precursor and the second precursor to the chamber in the absence of plasma during the chemisorbing; and successively repeating said chemisorbing and contacting under conditions effective to form a layer of material on the substrate comprising a conductive metal nitride.
