Abstract: A method of processing a substrate according to a PECVD process is described. Temperature profile of the substrate is adjusted to change deposition rate profile across the substrate. Plasma density profile is adjusted to change deposition rate profile across the substrate. Chamber surfaces exposed to the plasma are heated to improve plasma density uniformity and reduce formation of low quality deposits on chamber surfaces. In situ metrology may be used to monitor progress of a deposition process and trigger control actions involving substrate temperature profile, plasma density profile, pressure, temperature, and flow of reactants.

Abstract: Examples disclosed herein relate to a method and apparatus for cleaning and repairing a substrate support having a heater disposed therein. A method includes (a) cleaning a surface of a substrate support having a bulk layer, the substrate support is disposed in a processing environment configured to process substrates. The cleaning process includes forming a plasma at a high temperature from a cleaning gas mixture having a fluorine containing gas and oxygen. The method includes (b) removing oxygen radicals from the processing environment with a treatment plasma formed from a treatment gas mixture. The treatment gas mixture includes the fluorine containing gas. The method further includes (c) repairing an interface of the substrate support and the bulk layer with a post-treatment plasma. The post-treatment plasma is formed from a post-treatment gas mixture including a nitrogen containing gas. The high temperature is greater than or equal to about 500 degrees Celsius.

Abstract: A method of forming a film stack with reduced defects is provided and includes positioning a substrate on a substrate support within a processing chamber and sequentially depositing polysilicon layers and silicon oxide layers to produce the film stack on the substrate. The method also includes supplying a current of greater than 5 ampere (A) to a plasma profile modulator while generating a deposition plasma within the processing chamber, exposing the substrate to the deposition plasma while depositing the polysilicon layers and the silicon oxide layers, and maintaining the processing chamber at a pressure of greater than 2 Torr to about 100 Torr while depositing the polysilicon layers and the silicon oxide layers.

Abstract: Systems and methods for a process chamber that decreases the severity and occurrence of substrate defects due to loosened scale is discussed herein. A gas distribution assembly is disposed in a process chamber and includes a faceplate with a plurality of apertures formed therethrough and a second member. The faceplate is coupled to the second member which is configured to couple to the faceplate to reduce an exposed area of the faceplate and minimize an available area for material buildup during the release of gas into the process chamber. The second member is further configured to improve the glow of precursors into the process chamber. The gas distribution assembly can be heated before and during process chamber operations, and can remain heated between process chamber operations.
