<p>A positive resist composition for a thin-film implantation process of the present invention includes: a resin component (A) with an acid-dissociable dissolution inhibiting group, whose alkali solubility increases by the action of an acid; an acid generator component (B) which generates an acid by irradiation with radiation; and a compound (C) having a radiation absorbing ability, wherein said resin component (A) comprises a structural unit (a1) derived from a hydroxystyrene and a structural unit (a2) obtained by substituting the hydrogen atom in a hydroxyl group of said structural unit (a1) with an acid-dissociable dissolution inhibiting group, and said acid-dissociable dissolution inhibiting group contains an acid-dissociable dissolution inhibiting group (II) represented by the following general formula (II) as a main component.</p> |
