  • Publication number: 20230326777
    Abstract: Disclosed are semiconductor carrier storage systems, semiconductor fabrication systems including the same, and/or semiconductor fabrication methods using the same. The semiconductor carrier storage system comprises storage ports each of which accommodates a semiconductor carrier, a shuttle rail that extends in a horizontal direction on a side of the storage ports, an internal carrier shuttle that moves along the shuttle rail and transfers a semiconductor carrier to each of the storage ports, and an upper transport that receives the semiconductor carrier from an overhead hoist transport (OHT). The internal carrier shuttle includes a shuttle body coupled to the shuttle rail, a transfer wheel that connects the shuttle body to the shuttle rail, a gripper that holds the semiconductor carrier, and a hoist that vertically extends between the shuttle body and the gripper and drives the gripper to vertically move.

  • Publication number: 20230154779
    Abstract: A transfer apparatus according to the disclosure includes a mast portion including a base portion, and a protrusion portion protruding from the base portion, and a plurality of shuttles configured to move along the mast portion, thereby transferring a carrier. The mast portion includes a first magnet track fixed to a first sidewall of the protrusion portion, and a second magnet track fixed to a second sidewall of the protrusion portion. Each of the plurality of shuttles includes a first coil portion adjacent to the first magnet track in a horizontal direction, and a second coil portion adjacent to the second magnet track in the horizontal direction. The protrusion portion, the first magnet track, and the second magnet track are disposed between the first and second coil portions.
