摘要:
A positive resist composition comprising: (A) a resin showing an increase in the solubility in an alkali developer by the action of an acid; (B) a compound being capable of generating an acid when irradiated with an actinic ray or a radiation; (C) a resin having a silicon-containing repeating unit of a specific structure and being stable to acids but insoluble in an alkali developer; and (D) a solvent; and a pattern making method using the same.
