Abstract

Disclosed is a system for selectively managing workpieces used in the process of manufacturing semiconductor elements. The present invention comprises equipment for receiving a cassette having a plurality of workpieces and for executing a job on the workpieces; a database having job schedules on the workpieces and information on the cassette; and a controller for referring to workpiece information and job schedule information from the database and controlling the job of the equipment when the cassette is loaded into the equipment. This system provides for loading a cassette with workpieces equipment, and at the same time an equipment server and a host refers to job schedules of the workpieces from a file server, and select workpieces to be processed by the equipment. Since the selected workpieces are processed with different job schedules, the equipment can be automatically and remotely driven without manual mechanical manipulation and operator handling.
