  • Patent number: 7963737
    Abstract: Provided are an apparatus and method for transferring substrates. The substrate transferring apparatus is provided with a plurality of blades capable of withdrawing wafers from inside a container. Withdrawing members are elevated within coupling holes formed in the blades, and wafers are withdrawn by elevating and protruding the withdrawing members from the coupling holes of the blades. The withdrawing members are formed to be hollow, and are selectively elevated from the blades by supplying gas therein. Alternately, the withdrawing members are rotatably connected to the blades, and wafers are withdrawn when the withdrawing members are pivoted to protrude from the blades. Here, a withdrawing member includes a rotating shaft, and is pivoted when tension is applied to a wire wound around the rotating shaft. The wound wire is rotated by a driver that is selectively operated by a controller.
