    摘要: A pattern forming method, comprising:
    (A) coating a substrate with a positive resist composition of which solubility in a positive developer increases and solubility in a negative developer decreases upon irradiation with actinic rays or radiation, so as to form a resist film;
    (B) exposing the resist film; and
    (D) developing the resist film with a negative developer containing butyl acetate.

    摘要: The present invention is directed to a pattern forming method, comprising: forming a resist film by applying, to a substrate, a resin composition containing a resin of which solubility in a positive developer which is an alkali developer increases and solubility in a negative developer containing an organic solvent decreases under an action of an acid, wherein the resin composition is capable of forming a resist film of which solubility in the positive developer increases and solubility in the negative developer decreases upon irradiation with actinic rays or radiation;
    exposing the resist film with EUV light; and
    developing the resist film after the exposing with the negative developer containing an organic solvent.
