    摘要: A negative resist composition is used for either a first or second resist layer within a method of forming a resist pattern that includes the following steps (i) and (ii): (i) a step of forming the first resist layer on a substrate using a first resist composition, and then conducting selective exposure that forms a dense pattern in the first resist layer, and (ii) a step of forming the second resist layer on top of the first resist layer using a second resist composition, and then conducting selective exposure that forms a pattern in the second resist layer, wherein the negative resist composition is dissolved in an alcohol-based organic solvent, which functions as an organic solvent (D) that does not dissolve the first or second resist layer that contacts the resist layer formed from the negative resist composition.
