ABSTRACT:
In an apparatus and a method for cleaning semiconductor wafers, an exhaust chamber having a sub-outlet slows down the flow of frozen micro-particles and thus prevents rebounding of the particles toward the wafer. Therefore, dust or the like is kept away from a cleaned semiconductor wafer so that the semiconductor wafers are cleaned more thoroughly.
