  • Patent number: 5024329
    Abstract: A container for transporting and for storing semiconductor wafers situated in processing cassettes comprises a bottom plate, a hood, a locking lever and a seal element that is provided between the hood and the bottom plate. In order to avoid contamination of the semiconductor wafers during transport and during storage, the container is of such a nature that it is particle-tight and itself releases only a minimum of particles. The semiconductor wafer securing arrangement is movable on the basis of film hinges and is mechanically moved by the bottom plate when opening and closing the container, whereby no sliding friction occurs.

  • Patent number: 4804086
    Abstract: A transport container with an interchangeable, bipartite inside container includes an outside hood, an outside bottom plate, an inside hood, an inside bottom plate, two closing levers, a sealing element and a semiconductor holder. A filter element is built into the container to provide a particle-type transportation container for transporting and storing semiconductor wafers in a semiconductor wafer cassette and for use in differing air pressure conditions and air purity conditions.
