    摘要: A pattern-forming method includes coating a radiation-sensitive resin composition on a substrate to provide a resist film. The resist film is exposed. The exposed resist film is developed. A developer solution used in developing the exposed resist film includes no less than 80% by mass of an organic solvent. The radiation-sensitive resin composition includes a first polymer and a radiation-sensitive acid generator. The first polymer includes a first structural unit having an acid-labile group and an alicyclic group. The alicyclic group is capable of avoiding dissociation from a molecular chain by an action of an acid.

    摘要: A resist pattern-forming method includes coating a radiation-sensitive resin composition on a substrate to provide a resist film. The resist film is exposed. The exposed resist film is developed using a developer solution including no less than 80% by mass of an organic solvent. The radiation-sensitive resin composition includes a polymer, a radiation-sensitive acid generator, and an acid diffusion controller which includes a compound having an amide group. The polymer has a weight average molecular weight in terms of the polystyrene equivalent of greater than 6,000 and includes a first structural unit that includes an acid-labile group. The polymer includes less than 5 mol % or 0 mol % of a second structural unit that includes a hydroxyl group.
