Abstract

An apparatus for a semiconductor fabrication facility (FAB) is provided. In one embodiment, the apparatus includes a maintenance tool and a transporting tool configured to transport at least one customized. The maintenance tool includes a first track at a first horizontal plane, at least one maintenance crane movably mounted on the first track, and a plurality of first sensors on the first track. The first sensors are configured to define at least a danger zone and to detect a location of the maintenance crane. The transporting tool includes a second track at a second horizontal plane, at least one overhead hoisting transporting (OHT) vehicle movably mounted on the second track, and at least one second sensor on the OHT vehicle. The second horizontal plane is different from the first horizontal planes. The first horizontal plane and the second horizontal plane at least partially overlap each other from a plane view.
