Abstract:
A substrate transfer apparatus used for transferring a substrate between a substrate transfer container and a substrate processing apparatus, said substrate transfer apparatus comprising:a main body contained with the substrate; a first opening provided at the main body and connected to a substrate transfer port of the substrate transfer container while maintaining an air tight state against outside air; a second opening provided at the main body and connected to a substrate transfer port of the substrate processing apparatus while maintaining the air tight state against outside air, the opening having a door slidable between an open and closed position, an edge of the door resting in a groove when the door is in a closed position, the groove having seals disposed on opposite sides of the groove and positioned proximate opposite faces of the door when the door is in a closed state, wherein a pressure differential between one side of the door and an opposite side of the door presses the face of the door against one of the seals to assist in creating a hermetic seal; an exhaust pipe connected to the main body; an opening/closing mechanism for opening and closing a lid provided at the substrate transfer port of the substrate transfer container in a state in which the first opening and the substrate transfer port of the substrate transfer container are connected; a transfer mechanism installed at inside of the main body for transferring the substrate; and wherein the first opening is disposed at a top portion of the main body and positioned perpendicular to the second opening.
