  • Patent number: 11651984
    Abstract: A multiple transport carrier docking device may be capable of storing and/or staging a plurality of transport carriers in a chamber of the multiple transport carrier docking device, and may be capable of forming an air-tight seal around a transport carrier in the chamber. Semiconductor wafers in the transport carrier may be accessed by a wafer transport tool while the air-tight seal around the transport carrier prevents and/or reduces the likelihood that contaminants in the semiconductor fabrication facility will reach the semiconductor wafers. The air-tight seal around the transport carrier may reduce defects of the semiconductor wafers that might otherwise be caused by the contaminants, may increase manufacturing yield and quality in the semiconductor fabrication facility, and/or may permit the continued reduction in device and/or feature sizes of integrated circuits and/or semiconductor devices that are to be formed on semiconductor wafers.
