Abstract: Methods are provided for selectively depositing Al and N containing material on a first conductive surface of a substrate relative to a second, dielectric surface of the same substrate. In some aspects, methods of forming an Al and N containing protective layer or etch stop layer for use in integrated circuit fabrication are provided.

Abstract: A process for depositing titanium aluminum or tantalum aluminum thin films comprising nitrogen on a substrate in a reaction space can include at least one deposition cycle. The deposition cycle can include alternately and sequentially contacting the substrate with a vapor phase Ti or Ta precursor and a vapor phase Al precursor. At least one of the vapor phase Ti or Ta precursor and the vapor phase Al precursor may contact the substrate in the presence of a vapor phase nitrogen precursor.
