Patent ID: 7214467

Claim:
A photosensitive resin composition comprising: (A) a resin which decomposes by an action of acid to increase the solubility in alkali developer, in which the resin contains: a repeat unit having a group represented by the following general formula (Z); and a repeat unit having a group which decomposes by an action of acid to become an alkali soluble group; (B) a compound capable of generating an acid upon irradiation with one of an actinic ray and a radiation, in which the compound includes at least two kinds of compounds selected from the group consisting of compounds (B1), (B2), (B3) and (B4): (B1) a compound capable of generating aliphatic or aromatic sulfonic acid substituted with at least one fluorine atom upon irradiation with one of an actinic ray and a radiation; (B2) a compound capable of generating aliphatic or aromatic sulfonic acid containing no fluorine atom upon irradiation with one of an actinic ray and a radiation; (B3) a compound capable of generating aliphatic or aromatic carboxylic acid substituted with at least one fluorine atom upon irradiation with one of an actinic ray and a radiation; and (B4) a compound capable of generating aliphatic or aromatic carboxylic acid containing no fluorine atom upon irradiation with one of an actinic ray and a radiation; (C) a solvent; and (D) a surfactant: wherein R 50 to R 55 are the same or different, and represent a hydrogen atom, a fluorine atom, or an alkyl group which may have a substituent, and at least one of R 50 to R 55 represents a fluorine atom, or an alkyl group wherein at least one hydrogen atom is substituted with a fluorine atom.
