Abstract:
1. An insulating-film-forming composition for a semiconductor device comprising an organic silica sol with a carbon atom content of 11 to 17 atom % and an organic solvent, the organic silica sol comprising a hydrolysis-condensation product P1 and a hydrolysis-condensation product P2, the hydrolysis-condensation product P1 being obtained by hydrolyzing and condensing (A) a silane monomer comprising a hydrolyzable group and (B) a polycarbosilane comprising a hydrolyzable group in the presence of (C) a basic catalyst, and the hydrolysis-condensation product P2 being obtained by hydrolyzing and condensing (D) a silane monomer comprising a hydrolyzable group.
