Abstract
Methods and apparatus are provided for managing movement of small lots between processing tools within an electronic device manufacturing facility. In some embodiments, a number of priority lots to be processed is determined and an equivalent number of carrier storage locations are reserved at a substrate loading station of a processing tool. The number of reserved carrier storage locations are made available either by processing and advancing occupying non-priority lots and/or moving unprocessed occupying non-priority lots from the substrate loading station. Priority lots are then transferred to the reserved carrier storage locations. Other embodiments are provided.
