Methods and apparatus for performing an atomic layer deposition lithography process are provided in the present disclosure. In one embodiment, a method for forming features on a material layer in a device includes pulsing a first reactant gas mixture to a surface of a substrate disposed in a processing chamber to form a first monolayer of a material layer on the substrate surface, directing an energetic radiation to treat a first region of the first monolayer, and pulsing a second reactant gas mixture to the substrate surface to selectively form a second monolayer on a second region of the first monolayer.
