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. |

1. A resist composition comprising:
a polymer that comprises:
an acid-labile group-containing structural unit; anda structural unit that comprises a lactone structure, a cyclic carbonate structure, a sultone structure, or a combination thereof, a photoacid generator; and a solvent comprising:
a compound comprising a ketonic carbonyl group and an alcoholic hydroxyl group; andan alkylene glycol monoalkyl ether carboxylate, a content of the compound in the solvent being from 7 mass % to 35 mass %. |
