  • Patent number: 11987884
    Abstract: A method of inspection and an inspection system for the film deposition process for substrates includes glass and wafer. The inspection system includes multiple camera modules positioned in a load lock unit of a process chamber, such as the camera modules that can capture images of the substrate in the load lock. The images are analyzed by a control unit of the inspection system to determine the accuracy of robots in handling the substrate, calibration of the robots based on the analysis, and defects in the substrate caused during the handling and deposition process.
