Abstract: A semiconductor processing apparatus is provided, which includes processing chambers coupled together by transport mechanisms having transfer robots. After having completed wafer processing in each processing chamber, the allowable value of a time permitted for a processing-completed wafer to continue residing within the processing chamber is set up. Then, a time consumed up to the completion of transportation of a wafer scheduled to be next processed is estimated, thereby controlling a transfer robot in a way such that, when the estimated transfer time exceeds the allowable value of the waiting time, priority is given to an operation for unloading a processed wafer from the processing chamber insofar as the processed wafer's transfer destination is already in its state capable of accepting such wafer.
