An Si--O--F insulating film having a low dielectric constant is deposited on a substrate by thermally reacting disassociated SiF.sub.4 radicals and ozone or oxygen gas in a vacuum chamber. The SiF.sub.4 radicals are formed remotely from the chamber and interact thermally with the ozone or oxygen without requiring plasma enhancement. The deposited Si--O--F film has good gap-filling properties and is suitable for forming IMD layers over high aspect ratio 0.25 micron geometries.
