Patent ID: 7700262

Claim:
A substrate coated with a top coat material on top of a photoresist material on said substrate, the top coat material consisting essentially of a solvent and a polymer, said polymer comprising at least one fluorosulfonamide monomer unit having one of the following two structures: wherein: M is a polymerizable backbone moiety; Z is a linking moiety selected from the group consisting of —C(O)O—, —C(O)—, —OC(O)—, and —O—C(O)—C(O)—O—; R, is selected from the group consisting of an alkylene, an arylene, a semi- or perfluorinated alkylene, and a semi- or perfluorinated arylene; p and q are 0 or 1; R 2 is selected from the group consisting of hydrogen, fluorine, an alkyl group of 1 to 6 carbons, and a semi- or perfluorinated alkyl group of 1 to 6 carbons; n is an integer from 1 to 6; and R 3 is selected from the group consisting of hydrogen, an alkyl, an aryl, a semi- or perfluorinated alkyl, and a semi- or perfluorinated aryl.
