ABSTRACT:
Disclosed is an apparatus and method for transporting wafer cassettes. A wafer cassette handle is characterized by an elongated cylindrical handle positioned horizontal and in parallel to the front face of a wafer cassette and attached to the cassette by engagement members engaging grooves provided in the cassette. The operator's hand carries the handle and cassette by grasping the handle in an underhand grip with the back of the hand engaging the front face of the cassette or a support plate connected to the handle. The underhand grip minimizes wrist strain and encourages operators to hold the cassette high in the air, where particulate contamination is at a minimum.
