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: An apparatus for plasma processing a substrate is provided. The apparatus comprises a processing chamber, a substrate support disposed in the processing chamber, and a lid assembly coupled to the processing chamber. The lid assembly comprises a conductive gas distributor such as a face plate coupled to a power source, and a heater coupled to the conductive gas distributor. A zoned blocker plate is coupled to the conductive gas distributor and a cooled gas cap is coupled to the zoned blocker plate. A tuning electrode may be disposed between the conductive gas distributor and the chamber body for adjusting a ground pathway of the plasma. A second tuning electrode may be coupled to the substrate support, and a bias electrode may also be coupled to the substrate support.
