Abstract
A process for forming silicon dioxide, SiO.sub.2, or silicon nitride, Si.sub.3 N.sub.4, layers on selected substrates which includes reacting diethylsilane, C.sub.4 H.sub.12 Si, with a selected oxygen-containing compound or nitrogen-containing compound in a plasma enhanced chemical vapor deposition (PECVD) chamber. The conformality of the coatings thus formed is in the range of 85% to 98%. The diethylsilane liquid source for the associated gas flow processing system may be maintained and operated at a source temperature as low as room temperature.
