  • Publication number: 20220392789
    Abstract: An electronic device processing system includes a factory interface (FI), substrate carrier(s), a humidity sensor, an oxygen sensor, and an environmental control system coupled to the FI. A processor of the environmental control system is to cause inert gas to be provided to an FI chamber and inert gas exhausted from the FI chamber to be circulated back into the FI chamber. The processor is also to identify conditions to be satisfied before opening a door of the substrate carriers. The processor is to control the humidity level based on detection by the humidity sensor or the oxygen level based on detection by the oxygen sensor. If the one or more conditions are satisfied, the processor is to open the carrier door to enable passing of substrates between the FI chamber and the substrate carriers.

  • Patent number: 11450539
    Abstract: Electronic device processing systems including environmental control of the factory interface are described. One electronic device processing system has a factory interface having a factory interface chamber, a load lock apparatus coupled to the factory interface, one or more substrate carriers coupled to the factory interface, and an environmental control system coupled to the factory interface and operational to monitor or control one of: relative humidity, temperature, an amount of oxygen, or an amount of inert gas within the factory interface chamber. In another aspect, purge of a carrier purge chamber within the factory interface chamber is provided. Methods for processing substrates are described, as are numerous other aspects.

  • Patent number: 11282724
    Abstract: A factory interface for an electronic device processing system includes a factory interface chamber, an inert gas supply conduit, an exhaust conduit and an inert gas recirculation system. The inert gas supply conduit supplies an inert gas into the factory interface chamber. The exhaust conduit exhausts the inert gas from the factory interface chamber. The inert gas recirculation system recirculates the inert gas exhausted from the factory interface chamber back into the factory interface chamber.
