Abstract

An apparatus and method of passing messages between client systems is disclosed. The apparatus comprises a first client system and a second client system. The first client system assigns a priority to a message and transmits the message to the second client system. The second client system processes the message based on the priority. The apparatus can also include a message server coupled to both the first client system and the second client system and used to transmit the message from the first client system to the second client system. The apparatus can also include a log server, a diagnostics server, or both, which are both coupled to the message server and used to store log data used for archiving and diagnosis.

Claims

1. :

A message-passing system, comprising;

a. a first client system coupled to a semiconductor processor system and programmed to transmit a message packet containing a priority corresponding to a state of the semiconductor processing system;

b. a diagnostics server coupled to the first client system the diagnostics server programmed to store log data corresponding to the message packet and to map an error code corresponding to the state to a corrective action; and

c. a second client system programmed to receive the message packet transmitted from the first client system and process the message packet in an order relative to other message packets based on the priority.

2. The message-passing system of claim 1, wherein the first client system is programmed to transmit the message packet to the second client system according to a transport protocol.

3. The message-passing system of claim 2, wherein the transport protocol is TCP/IP.

4. The message-passing system of claim 2, wherein the transport protocol is NetBEUI.

5. The message-passing system of claim 1, wherein the message packet is formatted according to an SGML standard.

6. The message-passing system of claim 5, wherein the SGML standard is XML.

7. The message-passing system of claim 6, wherein the message packet comprises text data.

8. The message-passing system of claim 6, wherein the message packet comprises a virtual object.

9. The message-passing system of claim 1, further comprising a first message server coupling the first client system to the second client system, the first message server providing a first communication path between the first client system and the second client system.

10. The message-passing system of claim 9, further comprising a log server coupled to the first message server, the log server programmed to store log data for the message packet.

12. The message-passing system of claim 9, further comprising:

a second message server coupled to the first client system and the second client system, the second message server providing a second communication path between the first client system and the second client system; and

a load balancer coupling the first client system to both the first message server and the second message server, the load balancer further coupling the second client system to both the first message server and the second message server.

13. The message-passing system of claim 1, wherein the semiconductor processing system has an associated parameter, the first client system is programmed to monitor the associated parameter, generate the priority based on the parameter, generate the message packet containing the priority, and transmit the message packet to the second client system.

36. The message-passing system of claim 1, wherein the second client system comprises a priority queue structured for processing the message packet in the order based on the priority.

37. The message-passing system of claim 1, wherein the first client system is programmed to include a tag within the message packet when the priority is above a threshold, thereby indicating the occurrence of a diagnostics event on the first client system, and the message server is programmed to transmit to the diagnostics server all message packets that include the tag.

15. A method of passing a message packet between a first client system and a second client system, the method comprising:

a. generating the message packet containing a priority on the first client system, wherein the priority corresponds to a state of a semiconductor processing system;

b. transmitting the message packet from the first client system to the second client system and a diagnostics server, wherein the diagnostics server comprises a data store mapping the priority to a corrective action;

c. receiving the message packet on the second client system; and

d. processing the message packet on the second client system in an order relative to other message packets stored on the second client system based on the priority.

16. The method of claim 15, wherein the message packet is transmitted from the first client system to the second client system according to a transport protocol.

17. The method of claim 16, wherein the transport protocol is TCP/IP.

18. The method of claim 16, wherein the transport protocol is NetBEUI.

19. The method of claim 15, wherein generating the message packet comprises formatting a message according to an SGML standard.

20. The method of claim 19, wherein the SGML standard is XML.

21. The method of claim 20, wherein the message packet comprises text data.

22. The method of claim 20, wherein the message packet comprises a virtual object.

23. The method of claim 15, further comprising storing log data for the message packet.

24. The method of claim 15, wherein transmitting the message packet comprises:

transmitting the message packet to a message server based on a load of the message server; and

transmitting the message packet from the message server to the second client system.

25. The method of claim 15, wherein generating the message packet comprises encrypting a message to generate an encrypted message and including the encrypted message in the message packet.

26. The method of claim 25, wherein processing the message packet comprises decrypting the encrypted message in the message packet.

27. The method of claim 15, further comprising before the step (a):

reading a parameter associated with a manufacturing equipment; and

generating the priority based on the parameter.

38. The method of claim 15, further comprising taking the corrective action on the first client system, wherein taking the corrective action comprises cooling an area containing the semiconductor processing system.
