Method of producing organosilicon compound

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 is disclosed. The organic silica sol comprises a hydrolysis-condensation product P1 and a hydrolysis-condensation product P2. The hydrolysis-condensation product P1 is 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 is obtained by hydrolyzing and condensing (D) a silane monomer comprising a hydrolyzable group.
