    摘要: A method of processing a substrate including depositing a low dielectric constant film comprising silicon, carbon, and oxygen on the substrate and depositing an oxide rich cap on the low dielectric constant film is provided. The low dielectric constant film is deposited from a gas mixture comprising an organosilicon compound and an oxidizing gas in the presence of RF power in a chamber. The RF power and a flow of the organosilicon compound and the oxidizing gas are continued in the chamber after the deposition of the low dielectric constant film at flow rates sufficient to deposit an oxide rich cap on the low dielectric constant film.

    摘要: Stress of a silicon nitride layer may be enhanced by deposition at higher temperatures. Employing an apparatus that allows heating of a substrate to substantially greater than 400° C. (for example a heater made from ceramic rather than aluminum), the silicon nitride film as-deposited may exhibit enhanced stress allowing for improved performance of the underlying MOS transistor device. In accordance with alternative embodiments, a deposited silicon nitride film is exposed to curing with ultraviolet (UV) radiation at an elevated temperature, thereby helping remove hydrogen from the film and increasing film stress. In accordance with still other embodiments, a silicon nitride film is formed utilizing an integrated process employing a number of deposition/curing cycles to preserve integrity of the film at the sharp corner of the underlying raised feature. Adhesion between successive layers may be promoted by inclusion of a post-UV cure plasma treatment in each cycle.

    摘要: Methods for forming boron-containing films are provided. The methods include introducing a boron-containing precursor and a nitrogen or oxygen-containing precursor into a chamber and forming a boron nitride or boron oxide film on a substrate in the chamber. In one aspect, the method includes depositing a boron-containing film and then exposing the boron-containing film to the nitrogen-containing or oxygen-containing precursor to incorporate nitrogen or oxygen into the film. The deposition of the boron-containing film and exposure of the film to the precursor may be performed for multiple cycles to obtain a desired thickness of the film. In another aspect, the method includes reacting the boron-containing precursor and the nitrogen-containing or oxygen-containing precursor to chemically vapor deposit the boron nitride or boron oxide film.
