Abstract:
A dielectric film on a substrate formed by a method comprising:forming a solution of a solvent and an organohydridosiloxane resin comprising a polymer having a general formula:(H.sub.0.4-1.0 SiO.sub.1.5-1.8).sub.n (R.sub.0.4-1.0 SiO.sub.1.5-1.8).sub.m, or(H.sub.0-1.0 SiO.sub.1.5-2.0).sub.n (RSiO.sub.1.5).sub.m,wherein the sum of n and m is from about 8 to about 5000, m is selected such that the organic substituent is present in an amount of between about 0.1 and about 40 Mol %, and R, in any general formula, is selected from normal and branched alkyl groups, cycloalkyl groups, aryl groups, and mixtures thereof; andwherein the polymer has essentially no hydroxyl or alkoxy groups bonded to silicon atoms;dispensing the solution on the substrate;spinning the substrate to form an organohydridosiloxane resin coated substrate;baking the organohydridosiloxane resin coated substrate to remove any residual solvent, cause said polymer to flow, and partially convert said resin to said dielectric film; andcuring the organohydridosiloxane resin coated substrate, wherein said conversion to said dielectric film is completed.
