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.

Claim (Index 18):
A lid assembly for a semiconductor processing apparatus, the lid assembly comprising:\n a conductive gas distributor having a plurality of gas distributor openings; a first zoned plate comprising:\n one or more first plenums; and \n a first plurality of openings, wherein the first plurality of openings are in fluid communication with a first subset of the gas distributor openings; and \n a metrology device seated in the first zoned plate and in optical alignment with one of the first plurality of openings.
