Abstract: Methods of forming patterned features on a surface of a substrate are disclosed. Exemplary methods include gas-phase formation of a layer comprising an oxalate compound on a surface of the substrate. Portions of the layer comprising the oxalate compound can be exposed to radiation or active species that form exposed and unexposed portions. Material can be selectively deposed onto the exposed or the unexposed portions.
