Abstract:
A method for minimizing semiconductor wafer contamination, the method comprising the step of positioning a plurality of semiconductor wafers in a wafer storage device in a face down position with a backside of the wafers facing upward and a face of each of the wafers facing downward, and said wafers are located at a semiconductor processing station and said positioning step includes the steps of removing the wafers from the processing station, rotating the wafers so the backside of the wafers face upward and inserting the wafers into the storage device, and thereby preventing contaminants from falling from the backside of a wafer and landing on a face of the wafers positioned therebelow, further including the step of positioning a plurality of semiconductor wafers in alternating rotated and non-rotated positions with respect to one another.
