    摘要: A resist composition is provided comprising a polymer comprising recurring units having a hydroxyl group substituted with an acid labile group, an onium salt PAG capable of generating a sulfonic acid, imide acid or methide acid, and an onium salt PAG capable of generating a carboxylic acid. A resist film of the composition is improved in dissolution contrast during organic solvent development, and from which a hole pattern having minimized nano-edge roughness can be formed via positive/negative reversal.
