  • Patent number: 10837110
    Abstract: A substrate processing apparatus is provided to deposit a film including a reaction product on a substrate by repeating a supply cycle of sequentially supplying at least two kinds of reaction gases reactable with each other to a surface of the substrate in a chamber. The substrate processing apparatus includes a turntable provided in the chamber and having a concave portion for receiving the substrate formed in its surface and through-holes formed in the concave portion, a lifting mechanism including lift pins used when transferring the substrate placed on the concave portion, and a control unit configured to control the lifting mechanism. The control unit controls the lifting mechanism to carry the substrate out of the concave portion by moving the lifting pins upward in a vertical direction and inward in a radial direction of the turntable after the lifting pins contact the substrate through the through-holes.

  • Patent number: 8672602
    Abstract: The present invention is a processing apparatus comprising a transfer mechanism including at least one transfer plate, the transfer mechanism being configured to cause, when a substrate to be processed is placed on an upper surface of the transfer plate, the transfer plate to move while maintaining the substrate to be processed placed horizontally thereon. The transfer plate has a cantilevered support structure horizontally extending from a proximal end thereof to a distal end thereof in a fore and aft direction. An upper surface of the transfer plate is provided with a plurality of support projections configured to horizontally support the substrate to be processed at a substantially central position thereof and a rear position thereof in the fore and aft direction. The substrate to be processed is not supported on the distal portion of the transfer plate.

  • Patent number: 8565911
    Abstract: When a substrate is transferred by a holding arm to a multiple tier wafer boat, contact between the holding arm and the substrate is prevented. When the wafer boat is not subjected to a thermal effect, a normal height position of a ring member is obtained by relatively elevating and lowering a transfer base member with respect to the wafer boat. Before a wafer, which is not yet thermally processed, is transferred to the wafer boat, a height position of the corresponding ring member is obtained. By comparing a difference between the normal height position of the ring member and the height position of the ring member before the wafer is transported, with a threshold value, whether to transfer the wafer by the wafer transfer mechanism to the wafer boat can be judged.
