Abstract

A system and method for enabling a customer to monitor and modify an order in a semiconductor manufacturing system are provided. In one example, the method provides the customer with current information on the order, including a position of the order within the manufacturing process. The customer may request that the order be modified and the system may then determine when to implement the requested modification.

Claims

1. A method for enabling a customer to monitor and modify an order during semiconductor manufacturing using a centralized system, the method comprising:

providing manufacturing data to the customer via a computer, wherein the manufacturing data identifies a position of the order within a manufacturing process;

enabling the customer to request a modification to the order, wherein the request is made directly from the customer to the centralized system; and

approving or rejecting the requested modification if the modification must be verified before being implemented.

2. The method of claim 1 wherein approving or rejecting the requested modification is accomplished automatically by applying a set of design rules.

3. The method of claim 1 wherein the modification request is to modify a parameter associated with a product, a first process, or a first piece of equipment associated with the order.

4. The method of claim 3 further comprising incorporating the modification into the manufacturing process to alter the product, first process, or first piece of equipment prior to completing the manufacturing of the product.

5. The method of claim 3 wherein the manufacturing data includes a second process that is different from the first process, and wherein the method further comprises:

enabling the customer to make a modification to the second process; and

incorporating the modification into the manufacturing process to alter the second process prior to completing the manufacturing of the product.

6. The method of claim 5 further comprising providing an automated centralized access point accessible to both the customer and the centralized system, wherein the manufacturing data is provided to the customer for both the first and second processes using the centralized access point.

7. The method of claim 1 wherein providing manufacturing data to the customer occurs in real time.

22. The system of claim-2 further comprising instructions for automatically notifying the customer that the change has been enacted.

8. A method for enabling a customer to directly monitor and modify an existing order during semiconductor manufacturing using a centralized system, the method comprising:

receiving a request from the customer via the centralized system to change the order;

automatically identifying a current position of the order in a manufacturing process having a plurality of steps;

automatically determining at which step of the plurality of steps the change should be made based at least partly on the current position; and

making the change at the determined step.

9. The method of claim 8 further comprising notifying the customer via the centralized system that the change has been made.

10. The method of claim 8 further comprising:

providing manufacturing data to the customer via the centralized system prior to making the change;

updating the manufacturing data after making the change; and

providing the updated manufacturing data to the customer via the centralized system.

11. The method of claim 8 wherein automatically determining at which step of the plurality of steps the change should be made includes:

based on the current position, identifying a first step occurring after the current position that is separable from the current position; and

determining if the first step is compatible with the change, wherein the compatibility identifies whether the change will negatively impact the first step.

12. The method of claim 11 further comprising, if the first step is not compatible with the change, identifying a second step occurring after the first step that is separable from the first step.

13. A method for changing an existing order during a manufacturing process in a semiconductor manufacturing system, wherein the order is assigned an identifier for tracking within the system, the method comprising:

receiving a request from a customer to change the order, wherein the request is received by the semiconductor manufacturing system directly from the customer;

querying an order management system for a part number based on the identifier;

querying a work-in-process inventory system for a lot number based on the part number;

querying a product data management system for at least one process stage based on the part number;

querying a manufacturing execution system to convert the lot number and process stage to a plurality of process steps; and

determining when the change should be made based on the plurality of process steps and a current position of the order in the plurality of process steps.

14. The method of claim 13 further comprising:

instructing the manufacturing execution system to make the change at a particular step of the plurality of process steps; and

altering an execution of the plurality of process steps within a fabrication facility to enact the change.

15. The method of claim 14 further comprising automatically notifying the customer that the change has been enacted.

16. A centralized system for enabling a customer to monitor and modify an order during a semiconductor manufacturing process, the system comprising:

at least one equipment interface unit (EIU) associated with each of a plurality of separate manufacturing stations, wherein each station includes at least one piece of equipment that may be accessed via the EIU;

at least one manufacturing execution system (MES) in communication with each EIU;

at least one MES interface unit (MIU) in communication with each MES;

a centralized server in communication with each MIU; and

a customer interface unit (CIU) in communication with the centralized server, wherein the CIU is adapted to provide access to the centralized server by the customer.

17. The centralized system of claim 16 further comprising a plurality of computer executable instructions, the instructions including

instructions for receiving a request from the customer at the centralized server via the CIU to change the order;

automatically identifying, by the server via the MIU and the MES, a current position of the order in a manufacturing process having a plurality of steps, wherein the current position identifies which station is currently processing the order;

automatically determining at which step of the plurality of steps the change should be made based at least partly on the current position; and

instructing the MES to make the change in the station at the determined step via the EIU.

18. The centralized system of claim 17 further comprising instructions for retrieving and providing manufacturing data to the customer, wherein the manufacturing data identifies the current position.

19. The centralized system of claim 18 wherein the manufacturing data is retrieved and provided to the customer in real time.

20. A system for automatically implementing a customer initiated modification to an order in a semiconductor manufacturing environment, the system comprising:

an online system;

a work-in-process (WIP) inventory system in communication with the online system;

an order management system in communication with the online system;

a product data management system in communication with the online system;

a lot control system in communication with the online system;

a manufacturing execution system (MES) in communication with the lot control system; and

a plurality of instructions including;

instructions for receiving a request from a customer to change the order via the online system;

instructions for querying, by the online system, the order management system for a part number based on an identifier associated with the order;

instructions for querying, by the online system, the work-in-process inventory system for a lot number based on the part number;

instructions for querying, by the online system, the product data management system for at least one process stage based on the part number;

instructions for querying, by the lot control system, the MES to convert the lot number and process stage to a plurality of process steps; and

instructions for determining when the change should be made based on the plurality of process steps and a current position of the order in the plurality of process steps.

21. The system of claim 20 further comprising:

a fabrication facility in communication with the MES;

instructions for instructing the MES to make the change at a particular step of the plurality of process steps; and

instructions for altering an execution of the plurality of process steps within the fabrication facility to enact the change.
