  • Method for implementing an engineering change across fab facilities
    Patent number: 7415421
    Abstract: A method for managing a plurality of fabrication facilities comprises the steps of: identifying a proposed new or modified fabrication method, evaluating the fabrication method against decision criteria based on use of the fabrication method to fabricate a first product at a first one of the fabrication facilities, verifying the fabrication method against the decision criteria, based on using the fabrication method to fabricate a second product at a second one of the fabrication facilities, and adopting the fabrication method as a best known method among the plurality of fabrication facilities, if the fabrication method satisfies the decision criteria.
