Patent ID: 10043692

Abstract:
A substrate processing apparatus includes a substrate processing device, a substrate accommodation-status detection device, a substrate-transport device including a first substrate-transport sub-device which unloads substrates from a carrier and a second substrate-transport sub-device which unloads the substrates from the carrier, a control device including processing circuitry which controls the first and second substrate-transport sub-devices based on detection result of the substrate accommodation-status detection device. The processing circuitry of the control device determines a selection, based on the result of the substrate accommodation-status detection device, between a process in which the processing circuitry of the control device simultaneously drives the first and second substrate-transport sub-devices such that the first and second substrate-transport sub-devices simultaneously unload the substrates from the carrier and a process in which the processing circuitry of the control device drives only the second substrate-transport sub-device such that only the second substrate-transport sub-device unloads the substrates from the carrier.
