Abstract
A method of forming dielectric films is described wherein the low dielectric constant of a layer of dielectric material having a low dielectric constant, such as low dielectric constant spin-on-glass, is stabilized to prevent subsequent processing steps from increasing the dielectric constant. The layer of dielectric material having a low dielectric constant is treated in an inert atmosphere, such as nitrogen or argon, at an elevated temperature. This inert atmosphere treatment of the dielectric prevents the dielectric constant from increasing during subsequent processing steps.
