| 摘要 |
A copolymer of an acrylate monomer containing fluorine at alpha-position with a fluorinated hydroxystyrene derivative is highly transparent to VUV radiation and resistant to plasma etching. A resist composition using the polymer as a base resin is sensitive to high-energy radiation below 200 nm, has excellent sensitivity, resolution, transparency, substrate adhesion and plasma etching resistance, and is suited for lithographic microprocessing. |
