    摘要: A method of depositing a film on a substrate disposed in a substrate processing chamber. The method includes depositing a first portion of the film by forming a high density plasma from a first gaseous mixture flown into the process chamber. The deposition processes is then stopped and part of the deposited first portion of the film is etched by flowing a halogen etchant into the processing chamber. Next, the surface of the etched film is passivated by flowing a passivation gas into the processing chamber, and then a second portion of the film is deposited over the first portion by forming a high density plasma from a second gaseous mixture flown into the process chamber. In one embodiment the passivation gas consists of an oxygen source with our without an inert gas.

    摘要: Gap-fill and damascene methods are disclosed for depositing an insulating thin film of nitrofluorinated silicate glass on a substrate in a process chamber. A high-density plasma, generated from a gaseous mixture of silicon-, fluorine-, oxygen-, and nitrogen-containing gases, deposits a layer of nitrofluorinated silicate glass onto the substrate. For gap-fill applications, the substrate is biased with a bias power density between 4.8 and 11.2 W/cm2 and the ratio of flow rate for the oxygen-containing gas to the combined flow rate for all silicon-containing gases in the process chamber is between 1.0 and 1.8, preferably between 1.2 and 1.4. For damascene applications, the bias power density is less than 3.2 W/cm2, preferably 1.6 W/cm2, and the flow rate ratio is between 1.2 and 3.0. Using optimized parameters, the thin film has a lower dielectric constant and better adhesion properties than fluorosilicate glass.

    摘要: Embodiments of the present invention generally relate to the fabrication of solar cells and more specifically to a buffer layer for improving the performance and stability of surface passivation of Si solar cells. Generally, a passivation layer stack containing a buffer layer (interlayer) is formed on a surface of the silicon-based substrate. In one embodiment, the passivation layer stack may be formed on the back surface of the substrate. In another embodiment, the passivation layer stack is formed on the back surface of the substrate and a front emitter region (light receiving surface) of the substrate.
