Abstract:
A method for depositing a metal nitride film on a substrate, comprising:introducing a organometallic precursor into a processing chamber, wherein the organometallic precursor is selected from the group of compounds having the formulas of Nb(NRRâ€²)5. (NRRâ€²)3Nb&boxH;NRâ€³, and combinations thereof, wherein: R is a first organic functional group selected from the group consisting of alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, and combinations thereof, Râ€² is a second organic functional group selected from the group consisting of alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, and combinations thereof, Râ€³ is a third organic functional group selected from the group consisting of alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, and combinations thereof; introducing a processing gas into the processing chamber; generating a plasma of the processing gas and organometallic precursor in the processing chamber; and decomposing the organometallic precursor at a pressure of less than about 20 Torr to deposit the metal nitride film.
