Abstract:
A method for forming a pattern in a film carried on a substrate, comprising the steps of:depositing a film on a substrate;obtaining a mold having a protruding feature and a recess formed thereby, the feature and the recess having a shape forming a mold pattern wherein at least one mold pattern lateral dimension is less than 200 nm;wherein at least a portion of said protruding feature and a portion of said recess have bonded thereto a release material comprising an inorganic linking group bonded to a molecular chain having release properties;urging the mold into the film whereby the thickness of the film under the protruding feature is reduced and a thin region is formed in the film;removing the mold from the film, the film retaining a relief image thereon from the mold;processing the relief image whereby the thin region is removed exposing a portion of the surface of the substrate which underlies the thin region; andwhereby the exposed portion of the surface of the substrate substantially replicates the mold pattern, including replication of at least one mold pattern with a lateral dimension less than 200 nm.
