Abstract: Methods and related systems for lithographically defining patterns on a substrate are disclosed. An exemplary method includes forming a structure. The method includes providing a substrate to a reaction chamber. The substrate comprises a semiconductor and a surface layer. The surface layer comprises amorphous carbon. The method further comprises forming a barrier layer on the surface layer and depositing a metal-containing layer on the substrate. The metal- containing layer comprises oxygen and a metal.
