  • Publication number: 20220397706
    Abstract: Apparatus for heating a substrate within a substrate processing chamber are described herein. More specifically, possible lamp modules for use within a substrate processing chamber are described. The lamp modules include a reflector body. The reflector body is a reflective material. The reflector body includes grooves disposed in a surface and configured to direct radiant energy towards a substrate. Each ring includes multiple grooves with different cross sections to allow radiant energy to be directed at different radial positions on the substrate from the same ring. The grooves may be either curved or linear grooves.

  • Publication number: 20220380932
    Abstract: A method and apparatus for processing semiconductor substrates is described herein. The apparatus includes one or more growth monitors disposed within an exhaust system of a deposition chamber. The growth monitors are quartz crystal film thickness monitors and are configured to measure the film thickness grown on the growth monitors while a substrate is being processed within the deposition chamber. The growth monitors are connected to a controller, which adjusts the heating apparatus and gas flow apparatus settings during the processing operations. Measurements from the growth monitors as well as other sensors within the deposition chamber are used to adjust processing chamber models of the deposition chamber as substrates are processed therein.

  • Publication number: 20220375800
    Abstract: Embodiments disclosed herein generally relate to in situ monitoring of film growth in processing chambers. In some examples, a sensor assembly for a processing chamber includes a sensor tube including silicon carbide and having an optical path therein and a sensor window including crystalline silicon carbide and having a proximal side coupled to a distal end of the sensor tube. The sensor window covers the optical path, and a distal side of the sensor window facing away from the proximal side is perpendicular to a center axis of the optical path.

  • Publication number: 20220283029
    Abstract: 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.
