Abstract:
1. A method for processing a semiconductor workpiece, comprising: exposing a semiconductor workpiece in a processing zone to a vapor flow, the semiconductor workpiece being in fluid communication with a vapor supply that is configured to supply a plurality of vapor droplets to the processing zone, the semiconductor workpiece having an opening extending from a first surface of the semiconductor workpiece through the semiconductor workpiece to a second surface of the semiconductor workpiece facing opposite from the first surface, the opening having a contaminant; controlling a size of the vapor droplets in the vapor via a controller operatively coupled to the vapor supply and based on a size of the opening in the semiconductor workpiece; and drawing the vapor, the vapor droplets in the vapor, and the contaminant through at least a portion of the opening and away from the second surface of the semiconductor workpiece.
