  • Workpiece processing system for carrying out sequential execution of process of workpiece in each process chamber by setting start time of process in each process chamber based on necessary processing duration specific to each chamber and necessary conveyance duration between the chambers
    Patent number: 9989959
    Abstract: A workpiece processing system and method to process a workpiece in processing chambers in order, in which even if processing duration varies at any chamber, such a variation does not affect the processing of the workpiece in other chambers. Each chamber performs processing of a workpiece in a predetermined order; a conveyor that conveys a workpiece to a next chamber; and a control device controls at least a start time of predetermined processing at each processing chamber. The control device sets: predetermined representative processing at a first chamber as a reference processing step, start time of the reference processing step as control start time, necessary processing duration specific to each chamber, necessary conveyance duration required to convey a workpiece between the chambers, and controls starting of the representative processing at each chamber while considering the control start time as origination.
