The present disclosure relates to methods of correlating zones of processing chambers, and related systems and methods. In one implementation, a method of correlating zones of a processing chamber includes partitioning the processing volume into a plurality of zones along a first direction of the processing volume and a second direction of the processing volume.

The determining of the group number includes multiplying a first value by a second value. The first value correlates to a first zone number (m) of a plurality of zones and the second value correlates to a second zone number (n) of the plurality of zones. The method includes grouping the zones into groups having a number that is equal to the group number.

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.
