Wafer Cassette Transporting Patents (Class 414/940)
  • Patent number: 7935185
    Abstract: A clean gas circulates to pass through a loading area provided below a vertical heat treatment furnace. The clean gas unidirectionally flows through the loading area. After completion of wafer processing, a wafer boat lowers from the heat treatment furnace to the loading area, where the wafers are removed from the wafer boat. Subsequently, a clean gas jetting nozzle arranged in the loading area jets a clean gas toward the emptied wafer boat. Fragment of thin film which may readily peel off are blown away from the wafer boat, and are discharged out of the loading area together with the unidirectional flow. Thus, it is possible to avoid wafer contamination due to the unexpected peel-off of thin film fragments from the wafer boat.

  • Patent number: 7934898
    Abstract: A wafer processing system has a wafer loading system accommodating sufficient wafer carriers to substantially maximize the processing speed capability of the processing system. Wafer carriers are placed into and removed from the loading system by one or two overhead carrier loading tracks. Carriers may be loaded or removed while other carriers are in work. One or more transfer robots may move wafers from the carriers to buffers. One or more process robots in a process module move wafers from buffers, or other locations, to processors in the process module.

  • Patent number: 7651925
    Abstract: A frame and vacuum expansion chuck are used in combination for stretching a tape carrying a plurality of singulated devices to facilitate removal of the devices with reduced risk of contact between a device being removed from the tape and an adjacent device on the tape. The combination includes a frame for holding edges of a tape carrying a plurality of singulated devices, and a vacuum chuck having upper surfaces for contacting an underside of a tape carrying a plurality of singulated devices. The vacuum chuck extends along a perimeter circumscribing the singulated devices, and at least one groove is defined in the upper surface of the vacuum chuck. Conduit for providing fluid communication between the groove and a vacuum source are provided. Upon evacuation of the volume defined between the groove and the tape, the tape is drawn down into the groove and stretched, thereby increasing the separation or gap between adjacent dice and reducing the risk of damage upon removal of the dice.
