  • Method and apparatus for transferring articles between two controlled environments
    Patent number: 5547328
    Abstract: A method and apparatus for transferring articles from a transportable container, for example, a SMIF pod, to a second container, for example, a processing station having a port which provides access to the interior region of the processing station. A non-contact seal or an isolation cover or skirt seals the port so that the interior region of the container can be purged of contaminants prior to exposing the interior environment of the processing station to the environment within the container. The purging of the container may be a multi-step process in which the container door is moved between several intermediate positions so that the container door itself is purged prior to the purging of the environment within the container.
    Type: Grant
