  • Publication number: 20150122180
    Abstract: A substrate transfer apparatus includes a guide rail, a carrier, a magnetic levitation unit, and a transferring unit. The guide rail is in a vacuum evacuable chamber. The carrier may carry a substrate and may be linearly movable along the guide rail. The magnetic levitation unit is configured to generate a magnetic levitation force between the guide rail and the carrier. The transferring unit is configured to generate a momentum for linearly transferring the carrier and includes a plurality of first transferring magnetic material members on an upper surface of the carrier, a plurality of second transferring magnetic material members over the carrier and spaced apart from the first transferring magnetic material members, and a plurality of containers in which the plurality of second transferring magnetic material members is respectively disposed.
