Abstract

According to one embodiment, a method of forming a pattern includes the step of applying an actinic-ray- or radiation-sensitive resin composition on a substrate so as to form a film, the step of selectively exposing the film through a mask and the step of developing the exposed film with the use of a developer containing an organic solvent, wherein the actinic-ray- or radiation-sensitive resin composition contains a resin (A) whose polarity is increased by the action of an acid so that the solubility of the resin in the developer containing an organic solvent is decreased, a photoacid generator (B) that when exposed to actinic rays or radiation, generates an acid containing a fluorine atom and a solvent (C), and wherein the photoacid generator (B) is contained in the composition in a ratio of 8 to 20 mass % based on the total solids of the composition.
