    摘要: New polymers are provided comprising (i) one or more covalently linked photoacid generator moieties and (ii) one or more photoacid-labile groups, wherein the one or more photoacid generator moieties are a component of one or more of the photoacid-labile groups. Preferred polymers of the invention are suitable for use in photoresists imaged at short wavelengths such as sub-200 nm, particularly 193 nm.
