Publication number: 20220283029Abstract: One or more embodiments herein relate to methods for detection using optical emission spectroscopy. In these embodiments, 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.Type: ApplicationFiled: July 8, 2020Publication date: September 8, 2022Inventors: Zuoming ZHU, Martin A.
