Abstract:
A pattern forming method, including: (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; a positive resist composition for multiple development used in the method; a developer for use in the method; and a rinsing solution for negative development used in the method.
