  • Publication number: 20220367297
    Abstract: A diaphragm position of a valve may be detected and/or determined such that operation of the diaphragm may be monitored. A sensor included in the valve may generate sensor data that may be used to monitor the position of the diaphragm, which in turn may be used to determine a flow of a fluid through the valve. In this way, the sensor may be used to determine whether the diaphragm is properly functioning, may be used to identify and detect failures of the diaphragm, and/or may be used to quickly terminate operation of an associated deposition tool. This may reduce semiconductor substrate scrap, may reduce device failures on semiconductor substrates that are processed by the deposition tool, may increase semiconductor processing quality of the deposition tool, and/or may increase semiconductor processing yields of the deposition tool.
