An embodiment of the present disclosure aims to provide a logistics system capable of preventing congestion of transport vehicles in a specific section of a fabrication facility. According to the present disclosure, a logistics system in a fabrication facility includes a stocker equipment that is located near a central passage and stores an article, and a rail that provides a travel path of a transport vehicle that loads and unloads the article to the stocker equipment. The stocker equipment includes a load port disposed on a side opposite to the central passage and a rack that provides a space for storing the article. The rail includes a central rail formed along the central passage and a branch rail that is branched from the central passage and formed along the periphery of the load port.

A substrate container including a plate, a shell, a connector, and a seal, where the connector is threaded and secured via a nut, and the seal contacts each of the shell, plate, and connector. The plate has a recess accommodating an end of the connector and the nut. Field-serviceable, removable purge modules including check valves may be used with the substrate container, and may be secured to the substrate container in the recess in the plate. Filters may be secured to the connector or included in the purge modules. These filters may have diameters larger than an internal diameter of the connector.

A stocker system includes a main frame, a plurality of shelves disposed within the main frame, and a crane adjacent to the main frame. The crane includes a lower module that includes a plurality of lower profiles. An upper module is disposed on the lower module. The upper module includes a plurality of upper profiles and at least one upper expandable plate. The plurality of upper profiles is disposed on the plurality of lower profiles. The at least one upper expandable plate is disposed between the plurality of upper profiles.
