A method and apparatus are provided for initiating test runs based on a fault detection result. The method comprises receiving operational data associated with processing of a workpiece by a processing tool, processing the operational data to determine fault detection results; and causing a test run to be performed based on at least a portion of the fault detection results.

Initiating test runs based on fault detection results

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.

Conflict resolution among multiple controllers

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.

Dynamic metrology sampling techniques for identified lots, and system for performing same

A method and apparatus is provided for a process control based on an estimated process result. The method comprises processing a workpiece using a processing tool, receiving trace data associated with the processing of the workpiece from the processing tool and estimating at least one process result of the workpiece based on at least a portion of the received trace data. The method further comprises adjusting processing of a next workpiece based on the estimated at least one process result.

Process control based on an estimated process result

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.

Process control based upon a metrology delay

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.

Identifying a cause of a fault based on a process controller output

A method and an apparatus for the determination of a process flow based upon fault detection. A process step upon a workpiece is performed. Fault detection analysis based upon the process step performed upon the workpiece is performed. A workpiece routing process is performed based upon the fault detection analysis. The wafer routing process includes using a controller to perform one or a rework process routing, a non-standard process routing, a fault verification process routing, a normal process routing, or a termination process routing, based upon the fault detection analysis.
