Patent ID: 7923070

Claim:
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 comprising at least one of BH 3 and B 2 H 6 effective to react with the first species monolayer to remove organic groups from the first species monolayer, pressure within the chamber during the chemisorbing being lower than during the contacting; and successively repeating said chemisorbing and contacting under conditions effective to form a layer of material on the substrate comprising a conductive metal nitride.
