1. A method, comprising:
- processing a workpiece using a processing tool;
receiving trace data associated with the processing of the workpiece from the processing tool;
determining at least one value associated with a health of a portion of the processing tool based on at least a portion of the received trace data; and
adjusting processing of another workpiece based on the determined health value.

Abstract
A method is provided for a process control based on tool health data. 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 determining at least one value associated with a health of a portion of the processing tool based on at least a portion of the received trace data. The method further comprises adjusting processing of another workpiece based on the determined health value.

16. An article comprising one or more machine-readable storage media containing instructions that when executed enable a processor to:
-
receive trace data associated with processing of a wafer by a processing tool;
generate one or more health statistics associated with the operation of the processing tool based on at least a portion of the received trace data; and
provide at least one of the health statistic to a controller to adjust one or more parameters of the recipe based on the at least one health statistic. - View Dependent Claims (17, 18, 19, 20)
