摘要: A method for enhancing the reliability of copper interconnects and/or contacts, such as the bottom of vias exposing top surfaces of buried copper, or at the top of copper lines just after CMP. The method comprises contacting the exposed copper surface with a vapor phase compound of a noble metal and selectively forming a layer of the noble metal on the exposed copper surface, either by a copper replacement reaction or selective deposition (e.g., ALD or CVD) of the noble metal.

摘要: 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.
