  • Patent number: 8956807
    Abstract: A resist pattern-forming method capable of forming a resist pattern excellent in pattern collapse resistance in the case of development with the organic solvent in multilayer resist processes. The method has the steps of: (1) providing a resist underlayer film on a substrate using a composition for forming a resist underlayer film; (2) providing a resist film on the resist underlayer film using a photoresist composition; (3) exposing the resist film; and (4) developing the exposed resist film using a developer solution containing no less than 80% by mass of an organic solvent, in which the composition for forming a resist underlayer film contains (A) a component that includes a polysiloxane chain and that has a carboxyl group, a group that can generate a carboxyl group by an action of an acid, an acid anhydride group or a combination thereof.
