  • Patent number: 9164400
    Abstract: One pair each of a Y linear motor (a total of four) on the +X side and the ?X side that drive a reticle stage include one pair each of a stator section (a total of four) and three each of a mover section (a total of six) on the +X side and the ?X side. In this case, the three each of the mover sections on the +X side and the ?X side configure one each of a mover. The mover section located in the center in the Z-axis direction of each of the movers is used in common by each pair of the Y linear motors. Therefore, the weight of the mover section (reticle stage) of the reticle stage device is reduced, which allows a higher acceleration. Further, the mover section located in the center in the Z-axis direction of each of the movers coincides with a neutral plane of the reticle stage.
