Polymer, resist composition, and patterning process
摘要:
A chemically amplified resist composition using an alternating copolymer of α-trifluoroacrylic acid with norbornene as a base polymer lends itself to ArF laser lithographic micropatterning and is improved in transparency, plasma etching resistance, and line edge roughness.
