Patent ID: 8124327

Claim:
A method for generating a photoresist image on a substrate comprising: (a) coating the substrate with a photoresist film comprising (i) a macromolecule or a polymer comprising a monomer, and (ii) a photoacid generator, wherein the macromolecule and the monomer have the formula: where R 0 is selected from a molecular glass, C 2-20 alkylenyl and fluorinated alkylenyl, C 4-40 cycloalkylenyl, and fluorinated cycloalkylenyl, each optionally substituted with one or more heteroatoms; R 1 and R 2 are independently selected from C 1-20 alkyl and further R 1 and R 2 can be bonded together to form a cyclic group; L is a divalent C 1-20 alkyleneyl or cycloalkyleneyl optionally substituted with one or more substituents selected from C 1-20 alkyl and fluoroalkyl, and C 4-30 cycloalkyl optionally substituted with one or more substituents selected from one or more fluoro and heteroatom substituents; R 4 is selected from hydrido, trifluoromethyl, difluoromethyl, fluoromethyl, C 1-20 alkyl and C 4-20 cycloalkyl each optionally substituted with one or more fluoro substituents; and R 5 is selected from trifluoromethyl, difluoromethyl, fluoromethyl, C 1-20 alkyl, and C 4-20 cycloalkyl each substituted with one or more fluoro substituents, and further R 4 and R 5 can be linked to form a cyclic group; (b) imagewise exposing the film to radiation, wherein a liquid is disposed on the film during exposure of the film to radiation and the liquid has an index of refraction of about 1.40 or more; (c) heating the film to a temperature at or below about 90° C.; and (d) developing the image to the substrate.
