Patent number: 6133412Abstract: The present invention provides a process for generating mixed acetal polymers by reacting a hydroxyl containing polymer or monomer with vinyl ether and alcohol in the presence of an acid catalyst. The process of this invention provides a new class of polymers based on mixed acetals which are prepared in-situ with one reaction. The mixed acetal polymers are inexpensive to synthesize and readily reproducible. The resulting mixed acetal polymer is blended with a photoacid generator and dissolved in a solvent to produce a chemically amplified resist composition. A process for forming a pattern comprises the steps of providing the chemically amplified resist composition, coating a substrate with the resist composition, imagewise exposing the resist coated substrate to actinic radiation, and forming a resist image by developing the resist coated substrate.Type: GrantFiled: October 26, 1999Date of Patent: October 17, 2000Assignee: Arch Chemicals, Inc.Inventors: Sanjay Malik, Andrew J.
