COMPOUND, POLYMER, PATTERN FORMING MATERIAL, AND MANUFACTURING METHOD OF SEMICONDUCTOR DEVICE

A pattern forming material is configured to use for forming an organic film on a film to be processed, patterning the organic film, and then forming a composite film by infiltrating a metallic compound into the patterned organic film. The pattern forming material contains a polymer including a monomer unit represented by a general formula (3) described below, where R21 is H or CH3, each R22 is a hydrocarbon group of C2-14 where α carbon is primary carbon, secondary carbon or tertiary carbon, Q is a single bond or a hydrocarbon group of C1-20 carbon atoms which may include an oxygen atom, a nitrogen atom, or a sulfur atom between carbon-carbon atoms of or at a bond terminal, and a halogen atom may be substituted for the hydrogen atom.
