    摘要： In a method of depositing a crystalline germanium layer on a substrate, a substrate is placed in the process zone comprising a pair of process electrodes. In a deposition stage, a crystalline germanium layer is deposited on the substrate by introducing a deposition gas comprising a germanium-containing gas into the process zone, and forming a capacitively coupled plasma of the deposition gas by coupling energy to the process electrodes. In a subsequent treatment stage, the deposited crystalline germanium layer is treated by exposing the crystalline germanium layer to an energized treatment gas or by annealing the layer.

    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 some embodiments, a deposited silicon nitride film is exposed to curing with plasma and ultraviolet (UV) radiation, thereby helping remove hydrogen from the film and increasing film stress. In accordance with 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.
