    摘要: Fluorinated polymers useful in photoresist compositions and associated processes for microlithography are described. These polymers and photoresists have a fluoroalcohol functional group that simultaneously imparts high ultraviolet (UV) transparency and developability in basic media. The polymers also have a repeat unit derived from a C1-C25 alkyl hydroxymethylacrylate comonomer, e.g., tert-butyl hydroxymethylacrylate, or a C5-C50 polycyclic alkyl acrylate in which the polycyclic group contains a hydroxy group, e.g., hydroxyadamantyl acrylate. The materials of this invention have high UV tansparency, particularly at short wavelengths, e.g., 193 nm and 157 nm, which makes them highly useful for lithography at these short wavelengths.

    摘要: The invention provides an adhesive sheet comprising a surface stock and an adhesive layer, the adhesive layer containing a copolymer, the copolymer comprising, based on the copolymer; (a) 5 to 40% by weight of at least one member selected from a carboxylic acid-modified rosin ester monomer and a rosin ester monomer, and if desired, (b) 5 to 40% by weight of a (poly)ethylene glycol (meth)acrylate monomer, (c) 30 to 60% by weight of a (meth)acrylic acid C.sub.4-18 alkyl ester monomer, and if desired, (d) 20% by weight or less of an ethylenically unsaturated carboxylic acid-containing monomer, and (e) 20% by weight or less of another monomer which is copolymerizable with components (a), (b) and (c) and component (d) to be used when required. When the adhesive containing the copolymer comprising component (d) and a crosslinking agent, the adhesive sheet has removability. These adhesive sheets of the invention can be readily disintegrated without being adversely affected by the adhesive when the adhesive sheets are made into recycled pulp.
