Abstract
Provided herein are methods for selectively forming layers of metal films on one portion of a substrate while leaving adjacent portions of the substrate uncoated. The methods provide for selectively depositing metal films on a conductive surface, such as ruthenium oxide, disposed on or near an insulating portion of the substrate, such as a silicon dioxide (SiO) surface. The invention provides methods to simultaneously contact the substrate surface with both the precursor gas and the inhibitor agent leading to the selective formation of metal nuclei on the conductive portion of the substrate. In the methods described, nuclei are selectively formed by a disproportionation reaction occurring on the conductive portion of the substrate but not on the insulating portion of the substrate.
