    • There is disclosed a positive resist composition comprising at least:
      (A) a base resin, which has acidic functional groups protected by acid labile groups, respectively, and is insoluble or hardly soluble in alkali, and which is turned to be soluble in alkali upon elimination of the acid labile groups;
      (B) an acid generator; and
      (C) a nitrogen-containing compound as a basic component;

      wherein the base resin is: a polymer containing repeating units each represented by the following general formula (1); or a polymer containing repeating units each represented by the general formula (1), and containing at least one or more kinds of repeating units each represented by the following general formula (2) and repeating units each represented by the following general formula (3); and
      wherein the base resin contains the repeating units represented by the general formulae (1), (2), and (3), respectively, at a sum ratio of 70 mole % or more relative to a total amount of all repeating units constituting the base resin. There can be provided: a positive resist composition having an enhanced etching resistance and an excellent resolution and being capable of providing an excellent pattern profile even at a substrate-side boundary face of resist, in photolithography for fine processing, and particularly in lithography adopting, as an exposure source, KrF laser, extreme ultraviolet rays, electron beam, X-rays, or the like; and a pattern forming process utilizing the positive resist composition.
