  • Publication number: 20260136880
    Abstract: The present disclosure relates to a contamination controlled semiconductor processing system. The contamination controlled semiconductor processing system includes a processing chamber, a contamination detection system, and a contamination removal system. The processing chamber is configured to process a wafer. The contamination detection system is configured to determine whether a contamination level on a surface of the door is greater than a baseline level. The contamination removal system is configured to remove contaminants from the surface of the door in response to the contamination level being greater than the baseline level.
    Type: Application

  • Publication number: 20250161998
    Abstract: The present disclosure relates to an apparatus and a method for wafer cleaning. The apparatus can include a wafer holder configured to hold a wafer; a cleaning nozzle configured to dispense a cleaning fluid onto a first surface (e.g., front surface) of the wafer; and a cleaning brush configured to clean a second surface (e.g., back surface) of the wafer. Using the cleaning fluid, the cleaning brush can clean the second surface of the wafer with a scrubbing motion and ultrasonic vibration.

  • Publication number: 20200006101
    Abstract: The present disclosure describes a method for controlling a wet processing system includes dispensing one or more chemicals into a processing chamber according to one or more process parameters. The method also includes injecting one or more illumination markers into the processing chamber and obtaining images representing locations of the one or more illumination markers. The method further includes determining a trajectory of an illumination marker of the one or more illumination markers based on the images and determining whether the determined trajectory is outside a predetermined trajectory range. In response to the determined trajectory being outside the predetermined trajectory range, the method further includes adjusting the one or more process parameters.
