摘要:
A transfer flow is produced in accordance with a process recipe of a process to be carried out. In the transfer flow, a type of modules listed in accordance with a substrate transfer order is associated with a necessary staying time from when the substrate is transferred into a module by a substrate transfer unit to when the substrate is ready to be transferred back to the substrate transfer unit after the corresponding process is finished. A cycle limiting time is determined to be the longest necessary transfer cycle time among those obtained by dividing the necessary staying time by the number of the modules mounted in the coater/developer. The number of the modules to be used is determined to be a value obtained by dividing the necessary staying time by the cycle limiting time or a nearest integer to which the value is raised.

The present invention is a substrate processing method comprising the steps of successively extracting unprocessed wafers from a cassette, successively conveying the extracted wafers to a plurality of processing units, causing the processing units to process the wafers in parallel, and returning the processed wafers to a cassette. A process completion prediction time at which processes for one lot are completed is calculated and displayed corresponding to a process recipe that has been set to a plurality of wafers for at least one lot. Corresponding to the process completion prediction time, a cassette that contains a plurality of unprocessed wafers for one lot is accepted. A cassette that contains a plurality of processed wafers for one lot is returned.

A system comprises a first maintenance interval storage for storing a first maintenance interval of each component which is not related to an actual utilization of an apparatus, a second maintenance interval storage storing a second maintenance interval of each component which is related to the actual utilization of the apparatus, a maintenance demander for demanding maintenance of some component based on the passing of the first maintenance interval of this component; and a maintenance interval prolonger for judging the second maintenance interval has passed or not based on the passing of the first maintenance interval, and when the second maintenance interval has not yet passed, suspending the demand for maintenance by the maintenance demander and prolonging the first maintenance interval. Consequently, it becomes possible to manage a maintenance timing of each component and give notice thereof on the side of the apparatus composed of a plurality of components.
