Abstract: Processes are provided for selectively depositing thin films comprising one or more noble metals on a substrate by vapor deposition processes. In some embodiments, atomic layer deposition (ALD) processes are used to deposit a noble metal containing thin film on a high-k material, metal, metal nitride or other conductive metal compound while avoiding deposition on a lower k insulator such as silicon oxide. The ability to deposit on a first surface, such as a high-k material, while avoiding deposition on a second surface, such as a silicon oxide or silicon nitride surface, may be utilized, for example, in the formation of a gate electrode.
