Patent ID: 7977029

Claim:
A positive photosensitive composition comprising (A) an acid generator that generates an acid upon irradiation of an actinic ray or radiation, (B) a side chain type resin that has a monocyclic or polycyclic alicyclic hydrocarbon structure and is decomposed by the action of an acid to increase solubility in an alkali developing solution, and (C-2) a basic compound containing a substituted or unsubstituted aliphatic hydrocarbon group having not less than 8 carbon atoms; wherein the side chain type resin of component (B) consists of acrylate repeating units and/or methacrylate repeating units; the resin of component (B) contains at least one repeating unit having a group represented by the following formula (VI): wherein A 6 represents a single bond, an alkylene group, a cycloalkylene group, an ether group, a thioether group, a carbonyl group, an ester group or a combination of two or more thereof, and R 6a represents a hydrogen atom, an alkyl group having from 1 to 4 carbon atoms, a cyano group or a halogen atom; and the positive photosensitive composition further comprises (D) a fluorine and/or a silicon surface active agent.
