Abstract:
A computer-implemented method for transferring one or more wafers in a wafer processing facility comprising a plurality of process chambers, the method comprising the steps of:(1) receiving a plurality of wafers into the wafer processing facility; (2) assigning a different priority level to each of a plurality of wafers in the water processing facility according to a processing stage to which each respective wafer has progressed through the process chambers; (3) determining that a process in one or more of the process chambers has been completed; (4) determining which wafer of the plurality of wafers in the one or more process chambers is assigned a highest priority level; and (5) initiating a wafer transfer between two of the process chambers for the wafer having the highest assigned priority level.
