Abstract: A cleaning method for a UV chamber involves providing a first cleaning gas, a second cleaning gas, and a purge gas to one or more openings in the chamber. The first cleaning gas may be an oxygen containing gas, such as ozone, to remove carbon residues. The second cleaning gas may be a remote plasma of NF3 and O2 to remove silicon residues. The UV chamber may have two UV transparent showerheads, which together with a UV window in the chamber lid, define a gas volume proximate the UV window and a distribution volume below the gas volume. A purge gas may be flowed through the gas volume while one or more of the cleaning gases is flowed into the distribution volume to prevent the cleaning gases from impinging on the UV transparent window.

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.
