Patent ID: 7560794

Claim:
An electronic structure comprising a semiconductor substrate having a dielectric material comprising atoms of Si, C, O and H located on a surface thereof, said dielectric material having a covalently bonded tri-dimensional network ring structure comprising Si—O, Si—C, Si—H, C—H and C—C bonds, molecular scale voids having a diameter between 0.3 and 50 nm and occupying a volume between 0.5 to 50%, a dielectric constant of not more than 2.8, a crack propagation velocity in water of less than 10 −9 meters per second, a leakage current reduction that is about 10 or more, and a reflectance spectra that is substantially equivalent to SiO 2 , said reflectance spectra has about 60-70% reflectance at 248 nm.
