<p>A method is provided for processing a substrate surface by delivering a first gas mixture comprising a first organosilicon compound, a first oxidizing gas, and one or more hydrocarbon compounds into a chamber at deposition conditions sufficient to deposit a first low dielectric constant film on the substrate surface. A second gas mixture having a second organosilicon compound and a second oxidizing gas is delivered into the chamber at deposition conditions sufficient to deposit a second low dielectric constant film on the first low dielectric constant film. The flow rate of the second oxidizing gas into the chamber is increased, and the flow rate of the second organosilicon compound into the chamber is decreased to deposit an oxide rich cap on the second low dielectric constant film.</p> |
