摘要:
A method is provided for preparing a substrate for processing in a chamber that has a substrate receiving portion. The substrate is positioned within the chamber in a location not on the substrate receiving portion. A gaseous flow is provided to the chamber, from which a plasma is struck to heat the substrate. After the substrate has been heated, it is moved to the substrate receiving portion for processing.
摘要:
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.

摘要:
Methods are provided for identifying root causes of particle issues and for developing particle-robust process recipes in plasma deposition processes. The presence of in situ particles within the substrate processing system is detected over a period of time that spans multiple distinct processing steps in the recipe. The time dependence of in situ particle levels is determined from these results. Then, the processing steps are correlated with the time dependence to identify relative particle levels with the processing steps. This information provides a direct indication of which steps result in the production of particle contaminants so that those steps may be targeted for modification in the development of particle recipes.

摘要:
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.
摘要:
A method and 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.
