摘要: The resist polymer of the present invention comprises a specific constitutional unit having a cyano group, a constitutional unit having an acid-dissociable group, and a specific constitutional unit having a lactone skeleton. When the above polymer is used as a resist resin in DUV excimer laser lithography or electron beam lithography, it exhibits high sensitivity and high resolution, and provides a good resist pattern shape, having a small degree of occurrence of line edge roughness or generation of microgels.
