  • Publication number: 20230257875
    Abstract: A method of fabricating semiconductor devices includes: loading one or more semiconductor wafers into a plurality of stations provided within a process chamber; applying a process to the semiconductor wafers which deposits a material on the one or more semiconductor wafers within the process chamber; and cleaning the process chamber. Suitably, cleaning the process chamber includes flowing a cleaning gas into the process chamber toward a deflector arranged in the process chamber, the deflector having a first surface upon which the flowed cleaning gas impinges, the first surface directing a first portion of the flowed cleaning gas impinging thereon in a first trajectory toward a first end of the process chamber and directing a second portion of the flowed cleaning gas impinging thereon in a second trajectory toward a second end of the process chamber, the second end being opposite the first end.

  • Publication number: 20230257882
    Abstract: Methods and systems for chemical vapor deposition (CVD) are disclosed. The methods and systems use a showerhead including a domed internal baffle plate. The domed internal baffle plate is perforated. The presence of the domed internal baffle plate improves the uniformity of gas distribution through the holes of the showerhead across the surface area of the showerhead. This improves deposition uniformity on the semiconducting wafer substrate upon which CVD is being performed, or improves the cleaning of the reaction chamber when a cleaning gas is pumped in through the showerhead.

  • Publication number: 20230062038
    Abstract: A chamber of a semiconductor fabrication facility may include a vent port diffuser. The vent port diffuser may include a first tube member configured to couple the vent port diffuser to a vent port of the chamber. The vent port diffuser may include a second tube member coupled to the first tube member. The second tube member may comprise a plurality of openings spaced along a length of the second tube member, with the plurality of openings configured to receive a fluid from the chamber. Based on the semiconductor fabrication facility including the vent port diffuser, the chamber may be configured to provide an improved flow field of a fluid within the chamber. In this way, the vent port diffuser may reduce defects of semiconductor devices transported through the chamber that might otherwise be caused by contaminants.

  • 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.

  • Publication number: 20220367181
    Abstract: A method of manufacturing a semiconductor device includes detecting, using a sensor, liquid spin on glass (SOG) outside of a dispenser nozzle in an abnormal length relative to the dispenser nozzle. The method further includes adjusting, using a controller, a suck back (SB) valve to withdraw liquid SOG from the abnormal length. The method further includes comparing a sensed amount of liquid SOG deposited onto the semiconductor wafer from the dispenser nozzle with at least one set operating parameter. The method further includes pausing sensing of a duration of dispensing liquid SOG onto the semiconductor wafer based on the sensed amount of liquid SOG deposited being outside the at least one operating parameter.
