ABSTRACT:
A unidirectional gate disposed between interconnecting fluid transport regions in a manufacturing process. The gate allows workpieces to pass from a first transport region to a second transport region but prevents them from returning to the first region after having passed into the second region. The gate may specifically be used in semiconductor wafer manufacturing, especially where wafers exit a water track into a cassette.
