Abstract
A low-dielectric-constant interlayer insulating film, which is composed of at least one selected from the group consisting of: (i) a low-dielectric-constant borazine-silicon-based polymer substance obtainable by reaction of, in the presence of a platinum catalyst, B,B',B″-triethynyl-N,N′,N″-trimethylborazine with a specific silicon compound having at least two hydrosilyl groups; and (ii) a low-dielectric-constant borazine-silicon-based polymer substance obtainable by reaction of, in the presence of a platinum catalyst, B,B′,B″-triethynyl-N,N′,N″-trimethylborazine with a specific cyclic silicon compound having at least two hydrosilyl groups. A semiconductor device, which has the low-dielectric-constant interlayer insulating film. A low-refractive-index material, which is composed of the polymer substance (i) and/or (ii).
