A reticle management system is disclosed that provides data storage and
retrieval of data associated with each reticle, reticle carrier, and
certain system attributes and also for the efficient movement and storage
of reticles and reticle carriers. The reticle management system includes
a reticle management controller, a central reticle database, and one or
more reticle stockers that include a stocker controller, a stocker
database, and a stocker unit. The reticle management controller is
coupled to the central reticle database and each of the stocker
controllers. Each stocker controller collects data on the reticles,
reticle carriers, or both, that are stored within the associated stocker
unit and stores this data in the stocker database. The reticle management
controller retrieves the data in each stocker database via the associated
stocker controller and stores this data in central reticle database. In
addition, data attributes for the system, and the reticle carriers within
the system may also be stored in the central reticle database.
