发明名称 Resist composition, resist pattern-forming method, and resist solvent
摘要 A resist composition includes a polymer that includes an acid-labile group-containing structural unit, a photoacid generator, and a solvent. The solvent includes a compound that includes a ketonic carbonyl group and an alcoholic hydroxyl group. The alcoholic hydroxyl group is preferably a tertiary alcoholic hydroxyl group. The solvent preferably further includes an alkylene glycol monoalkyl ether carboxylate.
