摘要:
A positive resist composition for immersion exposure comprises: (A) a resin containing at least one repeating unit having a fluorine atom and increasing a solubility of the resin in an alkali developer by an action of an acid; and (B) a compound capable of generating an acid upon irradiation with one of an actinic ray and radiation.
