    摘要: A method of forming an image on a photoresist. The method includes: forming a photoresist over a substrate; applying a topcoat composition, the topcoat composition comprising at least one fluorine-containing polymer and a casting solvent, onto the photoresist; removing the casting solvent of the topcoat composition resulting in the formation of a topcoat material over the photoresist; exposing the photoresist to radiation, the radiation changing a chemical composition of the regions of the photoresist exposed to the radiation, forming exposed and unexposed regions in the photoresist; and removing i) the topcoat material and ii) the exposed regions of the photoresist or the unexposed regions of the photoresist.
