Abstract

A system comprises a parser operable to receive a log file containing detailed processing tool transactional data and generate an operation journal containing a subset of the detailed processing tool transactional data arranged in a known format, a comparator operable to receive automated material tracking data, and compare with the operation journal data, and an automatic correction module operable to automatically correct the automated material tracking data in response to a discrepancy between the automated material tracking data and the operation journal data.

Claims

1. A system comprising:

a parser operable to receive a log file containing detailed processing tool transactional data and generate an operation journal containing a subset of the detailed processing tool transactional data arranged in a known format;

a comparator operable to receive automated material tracking data, and compare with the operation journal data; and

an automatic correction module operable to automatically correct the automated material tracking data in response to a discrepancy between the automated material tracking data and the operation journal data.

2. The system of claim 1, including the comparator to further generate an electronic email alert in response to a discrepancy detected between the automated material tracking data and the operation journal data.

3. The system of claim 1, including the comparator to further generate a mismatch report in response to a discrepancy detected between the automated material tracking data and the operation journal data.

4. The system of claim 1, including the operation journal to comprise unique identifiers of material carriers located at a processing tool, a quantity of materials carried by each carrier, and timestamp.

5. The system of claim 1, further comprising the log file to contain detailed processing tool data of a predetermined time period.

6. The system of claim 1, further comprising the log file to contain detailed processing tool data in real time.

7. A system comprising:

a parser operable to receive a log file containing detailed processing tool transactional data and generate an operation journal containing a subset of the detailed processing tool transactional data arranged in a known format; and

a comparator operable to receive automated material tracking data, compare with the operation journal data, and generate an electronic alert in response to a discrepancy between the automated material tracking data and the operation journal data.

8. The system of claim 7, further comprising an automatic correction module operable to automatically correct the automated material tracking data in response to a discrepancy detected between the automated material tracking data and the operation journal data.

9. The system of claim 7, including the comparator to further generate a mismatch report in response to a discrepancy detected between the automated material tracking data and the operation journal data.

10. The system of claim 7, including the operation journal to comprise unique identifiers of material carriers located at a processing tool, a quantity of materials carried by each carrier, and timestamp.

11. The system of claim 7, further comprising the log file to contain detailed processing tool data of a predetermined time period.

12. The system of claim 7, further comprising the log file to contain detailed processing tool data in real time.

13. A method comprising:

receiving a log file containing detailed processing tool transactional data and generating an operation journal containing a subset of the detailed processing tool transactional data arranged in a known format;

receiving automated material tracking data and comparing the automated material tracking data with the operation journal data; and

automatically correcting the automated material tracking data in response to detecting a discrepancy between the automated material tracking data and the operation journal data.

14. The method of claim 13, further comprising generating an electronic email alert in response to a discrepancy detected between the automated material tracking data and the operation journal data.

15. The method of claim 13, further comprising generating a mismatch report in response to a discrepancy detected between the automated material tracking data and the operation journal data.

16. The method of claim 13, including generating an operation journal to comprise providing unique identifiers of material carriers located at a processing tool, a quantity of materials carried by each carrier, and timestamp.

17. The method of claim 13, wherein receiving a log file comprises receiving the log file containing detailed processing tool data of a predetermined time period.

18. The method of claim 13, wherein receiving a log file comprises receiving a log file containing detailed processing tool data substantially in real time.

19. A computer-readable medium having encoded thereon a process comprising:

receiving a log file containing detailed processing tool transactional data and generating an operation journal containing a subset of the detailed processing tool transactional data arranged in a known format;

receiving automated material tracking data and comparing the automated material tracking data with the operation journal data; and

automatically correcting the automated material tracking data in response to detecting a discrepancy between the automated material tracking data and the operation journal data.

20. The computer-readable medium of claim 19, further comprising generating an electronic email alert in response to a discrepancy detected between the automated material tracking data and the operation journal data.

21. The computer-readable medium of claim 19, further comprising generating a mismatch report in response to a discrepancy detected between the automated material tracking data and the operation journal data.

22. The computer-readable medium of claim 19, including generating an operation journal to comprise providing unique identifiers of material carriers located at a processing tool, a quantity of materials carried by each carrier, and timestamp.

23. The computer-readable medium of claim 19, wherein receiving a log file comprises receiving the log file containing detailed processing tool data of a predetermined time period.

24. The computer-readable medium of claim 19, wherein receiving a log file comprises receiving a log file containing detailed processing tool data substantially in real time.
