    摘要: A method of forming patterns includes (a) coating a substrate with a resist composition for negative development to form a resist film, wherein the resist composition contains a resin capable of increasing the polarity by the action of the acid and becomes more soluble in a positive developer and less soluble in a negative developer upon irradiation with an actinic ray or radiation, (b) forming a protective film on the resist film with a protective film composition after forming the resist film and before exposing the resist film, (c) exposing the resist film via an immersion medium, and (d) performing development with a negative developer.
