Abstract:
1. A method of forming a semiconductor device, comprising: providing a patterned substrate containing metal surfaces and dielectric layer surfaces; modifying the dielectric layer surfaces by exposure to a reactant gas containing a hydrophobic functional group, the modifying substituting a hydrophilic functional group in the dielectric layer surfaces with the hydrophobic functional group; and depositing metal-containing cap layers selectively on the metal surfaces by exposing the modified dielectric layer surfaces and the metal surfaces to a deposition gas containing metal-containing precursor vapor, wherein the depositing comprises: exposing the modified dielectric layer surfaces and the metal surfaces to the metal-containing precursor vapor to deposit metal layers selectively on the metal surfaces, wherein the metal-containing precursor vapor contains a metal element selected from platinum (Pt), gold (Au), ruthenium (Ru), cobalt (Co), tungsten (W), rhodium (Rh), iridium (Ir), or palladium (Pd), or a combination of two or more thereof, and incorporating a dopant into the metal layers by exposing the deposited metal layers to a dopant gas selected from PH
