  • Publication number: 20250218834
    Abstract: A load port receives a wafer carrier. An equipment front end module (EFEM) transfers semiconductor wafers to and from the wafer carrier via an access opening of a housing of the EFEM, and also transfers wafers to and from a semiconductor processing or characterization tool. A gas flow device disposed inside the housing of the EFEM is connected to receive a low humidity gas having relative humidity of 10% or less, and is positioned to flow the received low humidity gas across the access opening. A saturated pressure layer of the gas flow device has a permeability for the low humidity gas that increases with increasing distance from a gas inlet edge of the saturated pressure layer, for example due to holes of varying diameter and/or density passing through the saturated pressure layer. A filter layer of the gas flow device uniformizes the gas exiting the saturated pressure layer.

  • Publication number: 20240387218
    Abstract: A cart for wafer transportation includes a cart body, a separator disposed between first and second wafer holders, an airtight lock configured to seal the cart body. A wafer transfer system includes a cart including a space for holding a wafer holder, a first workstation configured to load the wafer holder into the space and pressurize the space, and a second workstation configured to depressurize the space and unload the wafer holder from the space, wherein the cart is transportable between the first workstation and the second workstation. A method for transporting wafers includes docking a cart in a workstation; loading a wafer holder into a space of the cart; pressurizing the space to cause a pressure of the space to be greater than an atmospheric pressure; maintaining the pressure of the space at the pressure; and moving the cart carrying the wafer holder away from the workstation.

  • Publication number: 20240379391
    Abstract: An airflow detection device is capable of detecting airflow issues associated with a transport carrier, such as a blockage of a diffuser in a transport carrier or leakage of a transition bracket, among other examples. The airflow detection device includes an air tunnel through which a gas in a transport carrier may flow. The airflow detection device includes an airflow sensor configured to generate airflow data based on a flow of the gas through the air tunnel. In some implementations, the airflow detection device is included in an airflow detection system to perform automated measurements and to determine, identify, and/or detect airflow issues associated with a transport carrier. In this way, the airflow detection system may perform one or more automated actions (or may cause one or more other devices to perform one or more automated actions) based on a detection of a diffuser blockage or a transition bracket leak.

  • Publication number: 20220368151
    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.
