  • Patent number: 7403882
    Abstract: Material handling systems that enable enhanced data consistency, and methods thereof, are disclosed. Behavior and life cycle of a semiconductor product for a material handling system are modeled in a set of finite states and trigger paths. A trigger event corresponding to a second finite state is generated when a transfer state of the product changes from a first finite state to a second finite state along trigger paths. Next, it is determined whether the trigger event complies with a predetermined control rule. Transport data between manufacturing execution and material handling systems is synchronized by message exchange.
