Patent Images
1. A method, comprising:
- receiving data associated with processing of a workpiece by a first processing tool;
receiving data associated with processing of a workpiece by a second processing tool; and
comparing at least a portion of the received data to a fault model common to both of the processing tools to determine if a fault associated with at least one of the processing of the workpiece by the first processing tool and processing of the workpiece by the second processing tool occurred.

Abstract
A method and an apparatus are provided for parallel fault detection. The method comprises receiving data associated with processing of a workpiece by a first processing tool, receiving data associated with processing of a workpiece by a second processing tool and comparing at least a portion of the received data to a common fault model to determine if a fault associated with at least one of the processing of the workpiece by the first processing tool and processing of the workpiece by the second processing tool occurred.

7. An apparatus, comprising:
-
an interface adapted to receive trace data associated with processing of workpieces by the first and second processing tools; and a control unit communicatively coupled to the interface, the control unit adapted to detect a fault associated with at least one of the first and second processing tool based on comparing at least a portion of the received trace data to a fault model representative of an acceptable operational range of at least the first and second processing tools. - View Dependent Claims (8, 9, 10, 11, 12, 13)

15. An article comprising one or more machine-readable storage media containing instructions that when executed enable a processor to:
-
receive data associated with processing of a workpiece by a first processing tool and receive data associated with processing of a workpiece by a second processing tool; and compare at least a portion of the received data to a fault model to determine if a fault associated with the processing of the workpiece by the first processing tool occurred, wherein the fault model is representative of the first and the second processing tool. - View Dependent Claims (16, 17, 18, 19)

20. A system, comprising:
-
a first processing tool adapted to process a wafer; a second processing tool adapted to process a wafer; and a fault detection unit adapted to; receive data associated with the processing of the wafer by the first processing tool and by the second processing tool; and detect a fault associated with at least one of the first and second processing tool based on comparing at least a portion of the received data to a fault model, wherein the fault model is representative of an acceptable operational range of at least the first and second processing tools. - View Dependent Claims (21)
