    Abstract: PROBLEM TO BE SOLVED: To easily execute cleaning of contamination of a lithographic apparatus. SOLUTION: The outer (top) surface of the reflective member 100 is co-planar with an outer (top) surface of the substrate table WT. This allows the reflective member 100 to be moved under the liquid supply system 12 without turning off the supply of liquid or the leaking of liquid. In that way the immersion space can be kept full of liquid as the reflective member 100 is moved under the projection system PS so that the reflective member 100 can be used in line. Cleaning fluid is applied to the immersion space and the cleaning liquid extends between the barrier member 12 and the reflective member 100 to a porous member 21. If the under pressure applied to the other side of the porous member 21 is reduced, the meniscus extending between the liquid supply system 12 and the reflective member 100 which defines the outer most edge of liquid moves radially outwardly to the outer edge of the porous member 21. Thus, the cleaning fluid covers all of the porous member 21. COPYRIGHT: (C)2011,JPO&INPIT

    解决方案:反射构件100的外(顶)表面与衬底台WT的外(顶)表面共面。 这允许反射构件100在液体供应系统12下移动而不关闭液体供应或液体泄漏。 以这种方式,当反射构件100在投影系统PS下方移动时,浸没空间可以保持充满液体,使得可以使用反射构件100。 清洁液被施加到浸没空间,清洁液体在阻挡构件12和反射构件100之间延伸到多孔构件21.如果施加到多孔构件21的另一侧的下压力减小, 液体供应系统12和限定液体最外边缘的反射构件100径向向外移动到多孔构件21的外边缘。因此,清洁流体覆盖所有多孔构件21.版权:( C)2011,JPO&INPIT
