    Abstract: Methods and apparatus are provided for the cleaning and drying of a work piece. The apparatus comprises a carrier configured to carry a work piece that has a surface. The apparatus further comprises a press plate having a first surface and a second surface. During a cleaning process, the carrier, the press plate, or both, is configured to move relative to the other. The press plate is disposed a distance from the surface of the work piece such that, when a cleaning fluid is disposed between the work piece and the press plate, the surface tension of the cleaning fluid maintains a meniscus between the work piece and the press plate. A mega-sonic transducer is coupled to the second surface of the press plate.
