    Abstract: A method of operating a substrate processing chamber. In one embodiment the method includes processing one or more substrates in the substrate processing chamber and subsequently cleaning the chamber using a dry cleaning process. This substrate processing and dry cleaning sequence is then repeated multiple times before chamber is further cleaned by flowing a cleaning gas into the chamber and forming a plasma within the chamber from the cleaning gas in an extended cleaning process. During the extended cleaning process the plasma is maintained within the chamber for a total of at least 5 minutes before the chamber is reused to process a substrate.

    Abstract: An apparatus for depositing a conformal dielectric layer employing a dep-etch technique features selectively reducing the flow of deposition gases into a process chamber where a substrate having a stepped surface to be covered by the conformal dielectric layer is disposed. By selectively reducing the flow of deposition gases into the process chamber, the concentration of a sputtering gas, from which a plasma is formed, in the process chamber is increased without increasing the pressure therein. It is preferred that the flow of deposition gases be periodically terminated so as to provide a sputtering gas concentration approaching 100%. In this fashion, the etch rate of a conformal dielectric layer having adequate gap-filling characteristics may be greatly increased, while allowing an increase in the deposition rate of the same.

    Abstract: A method and apparatus for controlling the introduction of contaminates into a deposition chamber that occur naturally within the chamber components. The CVD chamber is "seasoned" with a protective layer after a dry clean operation and before a substrate is introduced into the chamber. The deposited seasoning layer has a lower diffusion rate for typical contaminants in relation to the chamber component materials and covers the chamber component, reducing the likelihood that the naturally occurring contaminants will interfere with subsequent processing steps. After deposition of the seasoning layer is complete, the chamber is used for one to n substrate deposition steps before being cleaned by another clean operation as described above and then reseasoned.

    Abstract: A layer of reduced stress is formed on a substrate using an HDP-CVD system by delaying or interrupting the application of capacitively coupled RF energy. The layer is formed by introducing a process gas into the HDP system chamber and forming a plasma from the process gas by the application of RF power to an inductive coil. After a selected period, a second layer of the film is deposited by maintaining the inductively-coupled plasma and biasing the plasma toward the substrate to enhance the sputtering effect of the plasma. In a preferred embodiment, the deposited film is a silicon oxide film, and biasing is performed by application of capacitively coupled RF power from RF generators to a ceiling plate electrode and wafer support electrode.

    Abstract: A process for removing unwanted deposition build-up from one or more interior surfaces of a substrate processing chamber after depositing a layer of material over a substrate disposed in the chamber. In one embodiment the process comprises transferring the substrate out of the chamber; flowing a first gas into the substrate processing chamber and forming a plasma within the chamber from the first gas in order to heat the chamber; and thereafter, extinguishing the plasma, flowing an etchant gas into a remote plasma source, forming reactive species from the etchant gas and transporting the reactive species into the substrate processing chamber to etch the unwanted deposition build-up.
