A semiconductor wafer cleaning apparatus comprising a first supporting unit, a movable unit having a first chamber, a second supporting unit having a second chamber, and a third supporting unit is provided. A micro processing chamber in which the semiconductor wafer is being processed is formed when the first chamber is brought in contact with the second chamber. Each of the supporting units is supported by a corresponding supporting plate, and each supporting plate is positioned and strengthened by a plurality of supporting bars on its peripheral. Such design will prevent the deformation of the supporting plates, reduce the particles generated by the friction of parts resulted from the opening or closure of the micro processing chamber, and allow the easy alignment of these units. |
