Abstract: Embodiments of the present invention provide a film stack and method for depositing an adhesive layer for a low dielectric constant bulk layer without the need for an initiation layer. A film stack for use in a semiconductor device comprises of a dual layer low-K dielectric deposited directly on an underlying layer. The dual low-K dielectric consists of an adhesive layer deposited without a carbon free initiation layer.

Abstract: A method and apparatus for depositing a low K dielectric film with one or more features is disclosed herein. A method of forming a dielectric layer can include positioning a substrate in a processing chamber, delivering a deposition gas to the processing chamber, depositing a dense organosilicon layer using the deposition gas on the surface of the substrate, the dense organosilicon layer comprising a porogenic carbon, transferring a pattern into the dense organosilicon layer, forming a pore-forming plasma from a reactant gas, exposing the dense organosilicon layer to the pore-forming plasma to create a porous organosilicon layer, wherein the pore-forming plasma removes at least a portion of the porogenic carbon and exposing the porous organosilicon layer to a desiccating post treatment.
