Abstract:
1. A multilayer wiring structure comprising a silica film, wherein the silica film is formed by: coating a silica film forming material on a surface to be processed; and heating the surface to be processed, and wherein the silica film forming material comprises a silicone polymer which comprises, as part of its structure, an Si—O—Si bond, an Si—CH where x represents an integer of 0 to 2, and wherein the silicone polymer is obtained by hydrolysis condensation polymerization reaction of at least one silicon compound expressed by general formula (3) and at least one silicon compound expressed by general formulae (4) and (5) where, in the general formulas (3) to (5), n represents either 0 or 1; R′ may be the same as or different from each other, and represents one selected from the group consisting of a chlorine atom, a bromine atom, a fluorine atom, and a hydrogen atom when n=0, and represents one selected from the group consisting of a hydrocarbon with a carbon number of 1 to R R
