Manipulator for standard mechanical interface apparatus

Disclosed is a manipulator for removing a cassette holding articles, such as semiconductor wafers, to be processed from a container supported on a processing station in a standard mechanical interface (SMIF) system. The container is supported on an interface port on the canopy of the processing station and has a removeable door on which the cassette is supportable. A first platform is transportable along a shaft below the interface port and is operable to mate with the interface port and receive the cassette from the container. The first platform is transported down the shaft, thereby removing the cassette from the container. A second platform mounted in the shaft includes a manipulator arm which swings to engage the cassette on the first platform and support the cassette off of the first platform. The manipulator arm then pivots to transport the cassette to a location in the processing station away from the shaft. The first platform is then transported back up the shaft to the interface port to seal the container to prevent particulate contamination. The manipulator arm and the second platform after placing the cassette at a location in the processing station away from the shaft, are then positioned completely inside the shaft to minimize the space taken up in the processing station by the manipulator.

Long arm manipulator for standard mechanical interface apparatus

The present invention is an apparatus for maintaining articles, such as semiconductor wafers clean. The wafers or other articles to be processed are placed in a box having first and second regions for making first and second seals. A box door seals the articles into the box. The box has a second region for making the second seal and has a third region for making a third seal. The box is used to transport the wafers to a port in the canopy of the processing equipment. The port is adapted for receiving the box and box door and for transferring the box door and the contents of the box into a region beneath the canopy. The canopy has a first region for making the first seal with the box. Also, the canopy has a fourth region surrounding the port for making a fourth seal. A port door is provided for closing the canopy port when no box is present. The port door has a second region for making the second seal with the box and has a fourth region for making the fourth seal with the canopy. A box door latch is provided for latching the box door to the box whereby the second seal is made and released in the second region between the box door and the box by operation of the box door latch. A box latch is provided for latching the box to the canopy whereby the first seal is made or released in the first region between the box and the canopy by the operation of the box latch.
