Abstract: A human guided mobile loader stocker developed to mechanically assist in SMIF container movement. The assist includes a pushcart, a semi-motorized transport arm, a processor, and communication devices. A group of containers are placed on the cart using the arm. The cart is pushed to a semiconductor processing tool where the arm is used to transfer containers to and from the port of the processing tool. The processor and communication devices are used for inventory control and guiding the container to the port of the processing tool.

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.

Abstract: A transportable, sealable container, which has an improved pod liner. The container includes a box, a box door, and a gasket which forms a seal between the box and the box door. The box door has a conductive liner and a conductive path from the conductive liner to ground potential for electrostatic discharge protection. A membrane for isolating the gasket from the interior region of the container is bonded to the gasket and the conductive liner. The membrane may be impervious to gasses to prevent outgassing of the gasket or impervious to particles but not gasses to prevent particulate matter generated by the gasket from entering the interior region of the container.

Abstract: A system mounted with a transportable container for carrying articles such as semiconductor wafers which comprises a non-volatile memory used to store the identity, status and history of the articles in the container. Further, the system includes means for transmitting data from the memory to an information processor associated with a processing station which processes the articles in a carrier. In a preferred embodiment, the system includes data processing capability and both receives data from and transmits data to the processing station.

Abstract: A transportable, sealable container, for example a SMIF pod, has a box and a box door. The box has a first sealing surface and the box door has a second sealing surface which forms a seal with the first sealing surface when the box door is moved in a sealing direction with respect to the box. A latch mechanism provided in the box door is operable in two stages. The first stage of operation moves latch members from a retracted position to an extended position, in the retracted position the latch members are contained in the box door to allow movement of the box door with respect to the box, and in the extended position the latch members are adjacent to latch surfaces of the box. Movement from the retracted to the extended position is performed without contact between the latch members and the latch surfaces to avoid any scraping or rubbing action which would create particles in the "clean" interior region of the box.

Abstract: A system for storing transporting and processing articles includes a plurality of transportable containers, each transportable container having an interior region adapted to receive a plurality of articles and data processing device provided on the transportable container for receiving, storing, transmitting and displaying information related to the articles received by the corresponding transportable container. A plurality of workstations are adapted to receive one of the transportable containers and to process selected ones of the articles. The workstation also verifies that at least one of the articles in the transportable container has arrived at the appropriate workstation and communicates with a central processing unit to receive and transmit status information and processing information, and to transmit information stored by the data processing device provided on the transportable container.
