    摘要: Ester compounds having formula (1) wherein R1 is fluorine or C1-C10 fluoroalkyl, R2 is C1-C10 alkylene or fluoroalkylene, and R3 is an acid labile group are novel. They can be polymerized into polymers which are used to formulate resist compositions, which are processed by the lithography involving ArF exposure, offering many advantages including improved resolution and transparency, minimal line edge roughness, improved etch resistance, and especially minimal surface roughness after etching.

    摘要: A resist composition is provided comprising a polymer comprising recurring units having a protected hydroxyl group, a photoacid generator, an organic solvent, and a hydroxyl-free polymeric additive comprising fluorinated recurring units. A negative pattern is formed by coating the resist composition, prebaking to form a resist film, exposing, baking, and developing the exposed film in an organic solvent-based developer to selectively dissolve the unexposed region of resist film.
