  • Publication number: 20200225589
    Abstract: A substrate stage and an empty-weight canceling mechanism that supports an empty weight of the substrate stage are made up of separate bodies. Accordingly, the size and weight of the substrate stage (a structure including the substrate stage) can be reduced, compared with the case where the substrate stage and the empty-weight canceling mechanism are integrally configured. Further, due to movement of an X coarse movement stage and a Y coarse movement stage by an X drive mechanism and a Y drive mechanism, the substrate stage is driven in an XY plane and also the empty-weight canceling mechanism that supports the empty weight of the substrate stage is driven. With this operation, the substrate stage can be driven without difficulty even when the substrate stage and the empty-weight canceling mechanism are configured of separate bodies.

  • Patent number: 9846371
    Abstract: An exposure apparatus exposes a substrate by projecting a pattern image onto the substrate through a liquid. The exposure apparatus includes a projection optical system by which the pattern image is projected onto the substrate, and a movable member which is movable relative to the projection optical system. A liquid-repellent member, at least a part of a surface of which is liquid-repellent, is provided detachably on the movable member, the liquid-repellent member being different from the substrate.
