Resist underlayer film-forming composition containing polymer having alicyclic hydrocarbon group |
| abstract |
The present invention provides: a composition for forming a resist underlayer film that enables the formation of a desired resist pattern; a method for producing a resist pattern and a method for producing a semiconductor device, each of which uses the composition for forming a resist underlayer film. This composition for forming a resist underlayer film contains a polymer and a solvent, said polymer comprising a unit structure (A) represented by formula (1) [in formula (1): R 1 represents a hydrogen atom or an alkyl group having 1-6 carbon atoms; and L 1 represents an optionally substituted aliphatic ring, an aryl group having 6-40 carbon atoms or a hetero ring] and a unit structure (B) that contains an aliphatic ring in a side chain and that is different from the unit structure (A). |
