The first hydrocarbon-containing layer on the substrate is exposed to a reactant precursor to increase reactivity of the first hydrocarbon-containing layer on the substrate, and a second hydrocarbon-containing layer is deposited onto the first hydrocarbon-containing layer on the substrate. The process may be repeated to deposit the plurality of layers.
