    Abstract: A filter for filtering a fluid in a substrate processing apparatus comprises first and second stages that are connected to one another. A delivery system provides a vaporized liquid to the filter. The first stage of the filter comprises a basic compound, and the second stage of the filter comprises a desiccant. A second filter comprises a permeation filter with permeable membrane to filter the fluid. Methods of filtering the fluid to reduce formation of undesirable process residues using the filter(s) are also described.

    Abstract: 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.

    Abstract: Methods for forming silicon nitride hard masks are provided. The silicon nitride hard masks include carbon-doped silicon nitride layers and undoped silicon nitride layers. Carbon-doped silicon nitride layers that are deposited from a mixture comprising a carbon source compound, a silicon source compound, and a nitrogen source in the presence of RF power are provided. Also provided are methods of UV post-treating silicon nitride layers to provide silicon nitride hard masks. The carbon-doped silicon nitride layers and UV post-treated silicon nitride layers have desirable wet etch rates and dry etch rates for hard mask layers.
