Claim 9:
10. A method of depositing an iridium silicide film, the method comprising:
sequentially exposing a substrate surface maintained at a temperature in the range of about −25° C. to less than 300° C. to iridium hexafluoride and a silicon precursor, wherein the entire substrate surface is maintained at the temperature in the range of about −25° C. to less than 300° C. during the method; and
controlling one or more of a flow rate of the silicon precursor, a pulse time of the silicon precursor, or the temperature of the substrate surface to form an iridium silicide film with essentially no fluorine atoms and a predetermined silicon content, wherein the substrate surface comprises a first material consisting essentially of silicon and a second material comprising silicon oxide, silicon nitride or Al2O3 and the iridium silicide film is deposited selectively on the first material over the second material at a rate 15 times greater on the first material over the second material.
