Patent ID: 8603731

Claim:
A method of manufacturing a semiconductor device comprising: forming a resist underlayer film for electron beam lithography by applying a resist underlayer film forming composition for electron beam lithography on a substrate having a film to be processed on which a transferring pattern is formed and by heating the composition; coating the obtained resist underlayer film with a resist for electron beam lithography; and forming an integrated circuit element by: irradiating an electron beam to the substrate coated with the resist underlayer film for electron beam lithography and the resist for electron beam lithography; carrying out development; and performing dry-etching to transfer an image onto the substrate, wherein the resist underlayer film forming composition comprises: a polymer compound having a repeating unit structure that contains a halogen atom, a solvent, and a crosslinking agent, wherein the polymer compound is represented by Formula (1): wherein, L represents a bonding group constituting a backbone of the polymer compound; M represents a direct bond or a linking group containing at least one selected from —C(═O)—, —CH 2 — and —O—; Q represents an organic group; at least one of L, M and Q contains a halogen atom; and V represents the number of a unit structure contained in the polymer compound, which is the number of 1 to 3,000, and wherein the polymer compound contains at least 10% by mass of the halogen atom, based on the total mass of the polymer compound.
