Assignee: SCREEN HOLDINGS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A maintenance device for a substrate processing apparatus comprising:
a maintenance instruction device provided to correspond to the substrate processing apparatus;
a storage medium that stores authentication information corresponding to the substrate processing apparatus;
an authentication device that includes a first near field communicator and is provided to correspond to the substrate processing apparatus; and
an instruction terminal that includes a second near field communicator and a display, wherein
the maintenance instruction device produces screen information representing a maintenance screen for maintaining the substrate processing apparatus at which the maintenance instruction device is provided,
the authentication device includes
a first authentication information acquirer that acquires the authentication information stored in the storage medium using the first near field communicator when the storage medium is present in a communicable range of the first near field communicator of the authentication device,
a first determiner that determines whether the authentication information acquired by the first authentication information acquirer corresponds to the substrate processing apparatus at which the authentication device is provided, and
an information transmitter that transmits access information for communication between the instruction terminal and the maintenance instruction device provided at the substrate processing apparatus in a case where the acquired authentication information corresponds to the substrate processing apparatus, and does not transmit the access information in a case where the acquired authentication information does not correspond to the substrate processing apparatus,
the instruction terminal includes a network accessor that receives the access information using the second near field communicator and accesses the maintenance instruction device provided at the substrate processing apparatus through wireless communication using the received access information when the authentication device is present in a communicable range of the second near field communicator of the instruction terminal and the access information is transmitted using the first near field communicator,
a display controller that causes the display to display the maintenance screen based on screen information produced by the maintenance instruction device to which the network accessor has accessed, and
an operation unit that is to be operated by a user in order to instruct the substrate processing apparatus to perform a maintenance operation when the maintenance screen is displayed by the display.
