Zusammenfassung:Fluorinated polymers, photoresists and associated processes for microlithography are described. These polymers and photoresists are comprised of a fluoroalcohol functional group which simultaneously imparts high ultraviolet (UV) transparency and developability in basic media to these materials. The materials of this invention have high UV transparency, particularly at short wavelengths, e.g., 157 nm, which makes them highly useful for lithography at these short wavelengths.
