Abstract
A process for forming a nanoporous silica dielectric coating on a substrate. A substrate containing a deposited film is suspended within a sealable hotplate, while remaining free of contact with the hotplate. The hotplate is sealed and an inert gas is flowed across the substrate. The hotplate is heated to a temperature of from about 350° C. or higher, and the substrate is forced to contact the heated hotplate. The substrate is heated for a time that sufficiently removes outgassing remnants from the resultant nanoporous dielectric coating.
