  • Method for aligning wafers within a semiconductor wafer cassette
    Patent number: 5217341
    Abstract: An improvement which allows precise positioning of wafers within cassettes in preparation for removal of the wafers by automated equipment. The improvement includes mounting two sawtooth jigs upon the surface upon which the cassette tray is to be placed which extend up into the cassette. Wafers within the cassette rest within the precisely aligned grooves of the sawtooth jigs.When the cassette is placed upon the surface, automated equipment can readily remove the precisely aligned wafers from the cassette.
