Abstract:
1. An interlayer dielectric film having a plurality of metal interconnects disposed therein, said metal interconnects including a plurality of copper interconnects, at least two of which are adjacent to each other, the interlayer dielectric film further comprising an organic/inorganic hybrid film composed of a plurality of first sites of siloxane and a plurality of second sites of an organic molecule, wherein said plurality of first sites are separated from each other, each of said plurality of first sites being bonded to at least one of said second sites, said organic/inorganic hybrid film has a three-dimensional main chain composed of said first sites and said second sites, and in said three-dimensional main chain, said first sites are bonded to each other with said second sites interposed therebetween, the largest distance between the first sites of siloxane is smaller than the distance between the copper interconnects adjacent to each other, wherein each of said plurality of first sites is represented by the following general formula (1): wherein R wherein each of said plurality of second sites is polyimide, polyamide, polyimidazole, polyoxazole, polyphenylene, polyarylene, polyaryl ether, polyalkane or a fluorinated polymer of any of these polymers.
