    摘要: A photoresist composition is provided that includes a polymer having at least one acrylate or methacrylate monomer having a formula: where R1 represents hydrogen (H), a linear or branched alkyl group of 1 to 20 carbons, or a semi- or perfluorinated linear or branched alkyl group of 1 to 20 carbons; and where R2 represents an unsubstituted aliphatic group or a substituted aliphatic group having zero or one trifluoromethyl (CF3) group attached to each carbon of the substituted aliphatic group, or a substituted or unsubstituted aromatic group; and where R3 represents hydrogen (H), methyl (CH3), trifluoromethyl (CF3), difluoromethyl (CHF2), fluoromethyl (CH2F), or a semi- or perfluorinated aliphatic chain; and where R4 represents trifluoromethyl (CF3), difluoromethyl (CHF2), fluoromethyl (CH2F), or a semi- or perfluorinated substituted or unsubstituted aliphatic group. A method of patterning a substrate using the photoresist composition is also provided herein.

    摘要: A polymer blend is provided for use in a lithographic photoresist composition, particularly a chemical amplification photoresist. In a preferred embodiment, the polymer blend is substantially transparent to deep ultraviolet radiation, i.e., radiation of a wavelength less than 250 nm, including wavelengths of 157 nm, 193 nm and 248 nm, and has improved sensitivity and resolution. Processes for preparing and using the polymer blend are also provided, as are lithographic photoresist compositions that contain the polymer blend.

    摘要: The present invention involves a method for generating a photoresist image on a substrate. The method comprises coating a substrate with a film comprising a polymer comprising fluorocarbinol monomers; imagewise exposing the film to radiation; heating the film to a temperature of, at, or below about 90° C. and developing the image. The present invention also relates to a method for generating a photoresist image on a substrate where a polymer comprising fluorocarbinol monomers is used as a protective top coat.
