Abstract
A process for forming a extremely low dielectric constant film over a substrate. The process includes coating a substrate with a solution comprising a soluble source of silicon oxide, water, a solvent, a surfactant and a catalyst using an ultrasonic spray nozzle. The coated substrate is then subsequently treated to harden the solution into an extremely low dielectric constant film.
