A method and apparatus for processing a semiconductor substrate is described. A substrate processing apparatus is disclosed that includes a process chamber, a substrate support disposed inside the process chamber, a plurality of lamps arranged in a lamphead and positioned proximate to the substrate support, a gas source for providing a purge gas in a lateral flow path across the substrate support, and a controller that differentially adjusts power to individual lamps of the plurality of lamps based on a direction of the flow path.

Methods for detection using optical emission spectroscopy in which an optical signal is delivered from the process chamber to an optical emission spectrometer (OES). The OES identifies emission peaks of photons, which corresponds to the optical intensity of radiation from the photons, to determine the concentrations of each of the precursor gases and reaction products. The OES sends input signals of the data results to a controller. The controller can adjust process variables within the process chamber in real time during deposition based on the comparison. In other embodiments, the controller can automatically trigger a process chamber clean based on a comparison of input signals of process chamber residues received before the deposition process and input signals of process chamber residues received after the deposition process.
