Substrate processing apparatus and substrate processing method

1. Field of the Invention A resist coating/developing system is equipped with a cassette station, a process station and an inspection station. The inspection station comprise a defect inspection unit, a dummy inspection unit, a bypass inspection unit and a main wafer transfer device. When sampling inspections on wafer W that have completed processing in the process station, if a failure has occurred in the defect inspection unit, the inspection wafer is placed in the bypass inspection unit and excluding the inspection wafer, the non-inspection wafers are placed in the dummy inspection unit in the order that they were transferred to the inspection station and the wafer W is transferred from the inspection station to the cassette station in the order transferred from the process station to the inspection station.
