Patent ID: 6841256

Claim:
An adhesion promoter material prepared by a process, comprising: providing a polycarbosilane compound having the general formula: in which: R 1 , R 7 and R 10 each independently represents a substituted or unsubstituted alkylene, cycloalkylene, or arylene group; R 2 , R 3 , R 4 , R 5 , R 8 and R 9 each independently represents a hydrogen atom or a first organic group; R 6 represents an organosilicon, a silanyl, a siloxyl, or a second organic group; and x, y, z and w satisfying the conditions of [4<x+y+z+w<100,000], wherein y and w can collectively or independently be zero and wherein z>zero; coating a surface with the polycarbosilane compound to produce a polycarbosilane-coated surface; and subjecting the polycarbosilane-coated surface to an energy source to chemically react the polycarbosilane compound and to crosslink the polycarbosilane compound to form the adhesion promoter material that comprises a polyorganosilicon material, wherein the adhesion promoter material has a dielectric constant of less than 4.0.
