Maintenance device and maintenance method for substrate processing apparatus

A maintenance method for a substrate processing apparatus including a step of maintaining the substrate processing apparatus using a maintenance device,

• the maintenance device 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, and
• the step of maintaining includes
• acquiring 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, in the authentication device;
• determining whether the authentication information acquired by the first authentication information acquirer corresponds to the substrate processing apparatus at which the authentication device is provided, in the authentication device;
• transmitting 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 not transmitting the access information in a case where the acquired authentication information does not correspond to the substrate processing apparatus, in the authentication device;
• receiving the access information using a second near field communicator and accessing 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, in the instruction terminal;
• producing screen information representing a maintenance screen for maintaining the substrate processing apparatus at which the maintenance instruction device is provided, in the accessed maintenance instruction device;
• causing the display to display the maintenance screen based on the screen information produced by the accessed maintenance instruction device, in the instruction terminal;
• and
• instructing the substrate processing apparatus to perform a maintenance operation based on an operation performed on the instruction terminal by a user when the maintenance screen is displayed by the display, in the instruction terminal.
