PROCESS FOR PRODUCTION OF FLUORINE-CONTAINING NORBORNENE DERIVATIVES

摘要

There are provided a novel norbornene derivative which is a material for a chemically amplifying type photoresist for F2 laser, possesses excellent transparency and improved dry etching resistivity and has a fluorine-containing ketone unit or fluorine-containing tertiary alcohol unit directly bonded to the norbornene backbone; a fluorine-containing polymer obtained by using the norbornene derivative as a copolymerizable monomer; and a chemically amplifying type photoresist composition comprising the fluorine-containing polymer, a photoacid generator and a solvent.
