The dry process packaging material, allylundecamethylcyclohexasilane, is a high silicon content low molecular weight oligomer having the following composition: [Si(CH3)2]5 Si(CH3)(CH2CH=CH2) As the material has a high silicon content and contains only Si, C and H, toxicity and environmental problems are minimal. Furthermore, the material can be ashed to SiO2 or SiOx . The material can be converted to a SiOx etch barrier and can be used for planarization. The material has a moderate vapor pressure and can be vapor deposited. Since the material can be developed by heating, the wet processing steps associated with prior-art packaging materials are eliminated. The allylundecamethylcyclohexasilane of the present invention has been evaporated onto a substrate from heptane to form a 1200-Angstrom film.
