摘要:
A resist composition comprising a blend of a cyclic polymer having alcoholic groups as soluble groups and a polymer having carboxyl or hexafluoroalcohol groups whose hydrogen atoms are replaced by acid labile groups as a base resin forms a resist film which is improved in transparency, alkali dissolution contrast and plasma etching resistance.
