Abstract:
A positive photosensitive composition ensuring wide exposure latitude and reduced line edge roughness not only in normal exposure (dry exposure) but also in immersion exposure, a pattern forming method using the positive photosensitive composition, and a novel resin contained in the positive photosensitive composition are provided, which are a positive photosensitive composition comprising (A) a resin having a specific lactone structure in the side chain and being capable of increasing the solubility in an alkali developer by the action of an acid and (B) a compound capable of generating an acid upon irradiation with an actinic ray or radiation, a pattern forming method using the positive photosensitive composition, and a novel resin contained in the positive photosensitive composition.
