Abstract: Aspects of this disclosure relate to selective removal of material of a layer, such as a carbon-containing layer. The layer can be over a patterned structure of two different materials. Treating the layer to cause the removal agent to be catalytically activated by a first area of the patterned structure to remove material of the organic material over the first area at a greater rate than over a second area of the patterned structure having a different composition from the first area.
