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: In one embodiment, a polishing pad includes a hydrophilic polymer base having a polishing surface, and a metal oxide coating. The metal oxide coating has nanoparticles of metal oxide disposed on the polishing surface. In another embodiment, a processing station includes a rotatable platen, a polishing head, and a precursor delivery system. The polishing head is configured to retain a substrate against the polishing pad. The precursor delivery system is configured to form an oxide coating on a surface of a polishing pad disposed on the platen. In yet another embodiment, a method for modifying a surface of a polishing pad includes wetting the surface of the polishing pad and delivering a precursor to the wetted surface of the polishing pad surface. The method also includes forming a metal oxide coating having nanoparticles of metal oxide on the surface from the precursor.
