POLYMERIC COMPOUND CONTAINING REPEATING UNIT HAVING 2-OXATRICYCLO[4.2.1.04,8]NONAN-3-ONE RING, AND PHOTORESIST RESIN COMPOSITION |
摘要 |
<p>A polymeric compound of the invention includes at least one monomer unit represented by the following formula (I); wherein R a is a hydrogen atom, a halogen atom, an alkyl group of 1 to 6 carbon atoms or an haloalkyl group of 1 to 6 carbon atoms; each of R 1 and R 2 is identical to or different from a hydrogen atom or a hydrocarbon group, provided that at least one of R 1 and R 2 is a hydrocarbon group; R 1 and R 2 may be bonded together to form a ring with an adjacent carbon atom; and each of R 3 , R 4 , R 5 , R 6 , R 7 , R 8 and R 9 is identical to or different from a hydrogen atom or a hydrocarbon group. This polymeric compound has not only high substrate adhesion and high etching resistance but also high solubility for a resist solvent.</p> |
