  • Patent number: 5407350
    Abstract: A heat-treatment apparatus comprises a heat-treatment section for subjecting a heat-treatment to a wafer and a loading section for loading a wafer boat into and unloading it from the heat-treatment section. The loading section is connected to the heat-treatment section and includes in it a movable support member, a drive mechanism and a vertical base board as well as a load-lock chamber for maintaining the inside in vacuum. The movable support member supports a wafer boat. The movable support member is attached to a vertical base board so that it can move up and down. The drive mechanism is attached on the major surface of the vertical base board opposite to the surface facing the wafer boat. The drive mechanism drives the movable support to move up and down. The heat-treatment apparatus further comprises a wafer transfer section that includes an orientation flat alignment mechanism and a buffer stage disposed near the orientation flat alignment mechanism.

  • Patent number: 5404894
    Abstract: A thermal processing station is provided with a first conveyor that conveys a wafer from a first conveyor access portion and a second conveyor that conveys another wafer from a second conveyor access opening portion. The wafer conveyed from the first conveyor is conveyed along a route consisting of the second conveyor, a washing portion, the second conveyor again, the first conveyor, and a thermal processing portion. On the other hand, the wafer conveyed from the second conveyor is conveyed along a route consisting of the washing portion, the second conveyor again, the first conveyor, and the thermal processing portion. An intermediate transfer portion that is free to rotate and rise and lower is provided between the first and second conveyor. A control section does not rotate the intermediate transfer portion while the wafer is being transferred along the former route, but it does rotate the intermediate transfer portion through 180.degree.

  • Patent number: 5203445
    Abstract: A carrier conveying apparatus comprises a first carrier rest for placing carriers thereon, a second carrier rest to which the carriers are conveyed, a carrier holding member for holding a plurality of carriers at a time from below, a liftably moving mechanism for liftably moving the carrier holding member and a horizontally moving mechanism provided over a distance from below the first carrier rest to a position below the second carrier rest to horizontally move the carrier holding member and liftably moving mechanism. The liftably moving mechanism lifts the carrier holding member from below the first carrier rest and hence lifts the carriers placed on the first carrier rest in a manner to hold them by the carrier holding member. Then the horizontally moving means horizontally moves the carrier holding member and liftably moving mechanism to a position above the second carrier rest. Then the liftably moving mechanism lowers the carrier holding member to place the carriers on the second carrier rest.
