An information storage stores operation information regarding operations of an operating part group including a load port group, a processing unit group, and a transport mechanism. The operation information includes processing result information indicating a result of substrate processing performed by a substrate processing apparatus, and operational status information indicating temporal breakdowns of operational statuses of the substrate processing apparatus and operating parts included in the operating part group. The display controller displays the processing result information while arranging it according to an arrangement item selected from a predetermined arrangement item including an arbitrary operating period of the substrate processing apparatus. The display controller classifies the operational status information into broadly classified operational statuses and into specifically classified operational statuses and displays the classified operational status information. This enables an operator to easily recognize detailed operational statuses of the operating parts in association with the result of substrate processing.

A substrate transfer apparatus includes a transfer arm which includes a base portion; at least one arm portion connected to the base portion to extend from the base portion; a plurality of adsorption units provided in the at least one arm portion and each including a suction port that adsorbs a peripheral edge of a back surface of the substrate; and a plurality of suction passages provided in the at least one arm portion. The adsorption units include a first adsorption unit group including a first adsorption unit and a second adsorption unit; and a second adsorption unit group including a third adsorption unit and a fourth adsorption unit. The suction passages include a first suction passage connected to the suction ports of the first and second adsorption units, and a second suction passage connected to the suction ports of the third and fourth adsorption units.
