Technical Examples

This invention relates to resins and photoresist compositions that comprise such resins. Preferred polymers of the invention comprise adjacent saturated carbon atoms, either integral or pendant to the polymer backbone, that have a substantially gauche conformation. Polymers of the invention are particularly useful as a resin binder component of chemically-amplified positive-acting resists that can be effectively imaged at short wavelengths such as sub-200 nm and preferably about 157 nm. In such short-wavelength imaging applications, polymers of the invention that have a population of dihedral angles of adjacent saturated carbon atoms that are enriched in substantially gauche conformations can provide reduced undesired absorbance of the high energy exposure radiation.
