Abstract: Embodiments of the disclosure provide methods and system for manufacturing film layers with minimum lithographic overlay errors on a semiconductor substrate. In one embodiment, a method for forming a film layer on a substrate includes supplying a deposition gas mixture including a silicon containing gas and a reacting gas onto a substrate disposed on a substrate support in a processing chamber, forming a plasma in the presence of the depositing gas mixture in the processing chamber, applying current to a plasma profile modulator disposed in the processing chamber while supplying the depositing gas mixture into the processing chamber, and rotating the substrate while depositing a film layer on the substrate.

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.
