    摘要: A method and an apparatus are provided for conflict resolution among a plurality of controllers. The method includes receiving a first control instruction from a first process controller to process a workpiece, receiving a second control instruction from a second process controller to process the workpiece and adjusting at least one of the first control instruction and the second control instruction to process the workpiece to achieve a desired process goal.

    摘要: A method and apparatus is provided for identifying a cause of a fault based on controller output. The method comprises processing at least one workpiece under a direction of the controller and detecting a fault associated with the processing of the at least one workpiece. The method further includes determining a plurality of possible causes of the detected fault, identifying a more likely possible cause out of the plurality of possible causes, providing fault information associated with the identified more likely possible cause to the controller. The method further includes providing fault information associated with the identified more likely possible cause to the controller. The method further comprises adjusting the processing of one or more workpieces to be processed next based on the fault information provided to the controller. The method further includes generating prediction data associated with processing of the next workpieces, and comparing the prediction data to processing data associated with the processing of the next workpieces to identify a possible cause of the fault.

    摘要: Methods of using dynamic metrology sampling techniques for identified lots, and a system for performing such methods are disclosed. In one illustrative embodiment, the method comprises identifying at least one wafer to be processed, identifying a process tool in which at least one wafer is to be processed, obtaining enhanced metrology data regarding a process operation to be performed in the identified process tool prior to processing the identified at least one wafer in the identified process tool, and positioning at least one wafer in the identified process tool and performing the process operation thereon.

    摘要: A method and an apparatus for performing process control based upon a metrology delay. A process step is performed upon a first workpiece. Metrology data related to the first workpiece is acquired. A control adjustment based upon the metrology data is determined. A magnitude of the control adjustment is modified based upon a time period. The time period is defined by a first time frame relating to processing the first workpiece and a second time frame relating to acquiring metrology data related to the first workpiece.
