The liquid immersion member includes a first member that is disposed at at least a portion of surrounding of the optical member; a second member that is capable of being opposite to the object and is movable outside an optical path of the exposure light; and a protection part that protects the optical member. The protection part decreases a change in pressure which the optical member receives from the liquid in the liquid immersion space.

  • Patent number: 10107943
    Abstract: The present disclosure relates to an optical arrangement for use in an optical imaging process. The optical arrangement includes an optical element, an immersion zone and a liquid repelling device. During the optical imaging process, the immersion zone is located adjacent to the optical element and is filled with an immersion liquid. The optical element has a first surface region and a second surface region. During the optical imaging process, the first surface region is wetted by the immersion liquid. At least temporarily during the optical imaging process, the liquid repelling device generates an electrical field in the region of the second surface. The electrical field being is adapted to cause a repellent force on parts of the immersion liquid which are responsive to the electrical field and inadvertently contact the second surface region. The repellent force has a direction to drive away the parts of the immersion liquid from the second surface region.
