  • Publication number: 20220139757
    Abstract: A wafer sorting and stoking system provides automated storage and retrieval of wafer frames carrying semiconductor wafers. A wafer frame cassette is received at a transfer port from a transfer system. A robot arm retrieves the wafer frames from the cassette and stores each wafer frame in a respective storage slot in one of a plurality of storage towers. The storage location of each wafer frame is recorded. Each wafer frame can be selectively retrieved and loaded into a wafer frame cassette by the robot arm for further processing.

  • Patent number: 11302553
    Abstract: A transport carrier docking device may be capable of forming an air-tight seal around a transport carrier while a front portion of the transport carrier is inserted into a chamber of the transport carrier docking device. Semiconductor wafers in the transport carrier may be accessed by a transport tool while the air-tight seal exists around the transport carrier, which prevents and/or reduces the likelihood that contaminants in a 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.

  • Publication number: 20210376649
    Abstract: An under-floor charging station can be mounted under a floor such that a top plate of the under-floor charging station is substantially flush with a top surface of the floor without touching the ground. Openings in the top plate allow charging elements to extend when in use to charge a mobile robot, and to retract under the floor when not in use. The retractable charging elements prevent tripping hazards and allow the mobile robot to move freely throughout a clean room. Moreover, because the charging elements can be retracted in an unobtrusive position when the under-floor charging station is not in use, the under-floor charging station is permitted to be positioned in locations in the clean room that allow the mobile robot to continue working while charging and/or allow non-stop running of the mobile robot.
