Abstract:
A process for forming a dielectric material on a semiconductor device comprisinga) providing a first conductor and a horizontally adjacent second conductor, formed on a substrate wherein a gap is formed between the conductors;b) applying to the electronic substrate a polycarbosilane of the general formula ##STR4##in which:R.sub.1, R.sub.7, and R.sub.10, each independently represents a substituted or unsubstituted alkylene, cycloalkylene, or arylene group; R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.8 and R.sub.9 each independently represents a hydrogen atom or organic group, R.sub.6 represents an organosilicon, a silanyl, a siloxyl, or an organo group; and x, y, z and w satisfying the condition of, and y and z and w can collectively or independently be zero wherein the gaps between said conductors are filled,c) heating the polycarbosilane coated substrate in multistages at sequentially elevated temperatures of from about 50.degree. C. to about 400.degree. C. to inter-react and cross-link the polycarbosilane to form a polyorganosilicon material layer in the gaps; andd). curing the polycarbosilane coated substrate to complete conversion of the polyorganosilicon mate to a low dielectric constant material.
