  • Patent number: 8101013
    Abstract: A film-forming material that is capable of forming, at a low temperature, a film having a high degree of etching resistance and a high etching selectivity ratio relative to an organic film, as well as a method of forming a pattern that uses the film-forming material. The film-forming material includes a metal compound (W) capable of generating a hydroxyl group upon hydrolysis, and a solvent (S) in which the metal compound is dissolved, wherein the solvent (S) includes a solvent (S1) with a boiling point of at least 155° C. that contains no functional groups that react with the metal compound (W). The method of forming a pattern includes the steps of: coating a pattern, which has been formed on top of an organic film of a laminate that includes a substrate and the organic film, using the above film-forming material, and then conducting etching of the organic film using the pattern as a mask.
