    摘要: It has been discovered that a parasitic plasma problem which has existed with respect to incoming plasma source gases present in a source gas feed line to a plasma processing chamber can be avoided. The stability of a parasitic plasma is avoided by installing an RF resistor conduit in the source gas feed line and increasing the pressure in the RF resistor conduit through which the plasma source gases flow. Use of a variable surface restrictor in the RF resistor conduit or between the RF resistor conduit and the plasma processing chamber enables not only avoidance of the formation of a parasitic plasma in incoming plasma source gases, but also easier cleaning of the processing chamber plasma generation system when a remotely generated plasma is used for such cleaning.

    摘要: The present invention generally comprises a diffuser plate for a PECVD chamber. The diffuser plate comprises a plurality of hollow cathode cavities. The edge of the diffuser plate that will reside closest to a slit valve within a processing chamber may have the shape and/or size of the hollow cathode cavities adjusted to compensate for the proximity to the slit valve. By adjusting the shape and/or size of the hollow cathode cavities closest to the slit valve, the diffuser plate may permit a uniform plasma distribution across the processing chamber and thus, a uniform film thickness upon a substrate during a PECVD process.
