摘要 |
The photosensitive polymer includes a first monomer which is norbornene ester having C<SUB>1 </SUB>to C<SUB>12 </SUB>aliphatic alcohol as a substituent, and a second monomer which is maleic anhydride. A chemically amplified photoresist composition, containing the photosensitive polymer, has an improved etching resistance and adhesion to underlying layer materials, and exhibits wettability to developing solutions.
