  • Requalification controller for durables
    Patent number: 6427090
    Abstract: A system is provided for controlling the time at which a durable item, such as a reticle used in a lithography process in semiconductor manufacturing, is requalified for use. A counting device counts occurrences of predefined events, such as the number of jobs in which the reticle is used or the number of times it is placed in a lithography tool. The reticle is not removed from use until a limiting number of jobs or tool placements is reached, or the reticle is needed for processing the requalification job. The system also includes a requalification device for the durable item.
