  • Semiconductor wafer container
    Patent number: 4666479
    Abstract: This invention relates to a semiconductor wafer container having an air filter for removing fine particles from air, which serves to allow air to pass through a body of the container. This causes atmospheric pressure within and without the container body to be substantially identical to each other whereby dirty air is never introduced into the container body.
