Patent ID: 7489388

Claim:
A lithographic apparatus comprising: an illumination system constructed to provide a beam of radiation onto a substrate; a patterning device configured to impart a cross-section of said beam of radiation with a pattern; a chuck assembly constructed to support said substrate or said patterning device; a long-stroke module constructed to at least partially position said chuck assembly relative to other components of the lithographic apparatus, the long-stroke module being vibrationally isolated from said chuck assembly; and a heat transfer system constructed to transfer heat between a first surface and a second surface, said first surface being formed by said chuck assembly, and said second surface being formed by said long-stroke module, said second surface being spaced a distance from said first surface so as to define a substantially empty space between the first surface and the second surface, the empty space extending over substantially the area defined by the second surface, said second surface being thermally coupled to said first surface, wherein said heat transfer system includes a surface heat transfer device capable of transferring heat from or to said second surface, a portion of said surface heat transfer device being positioned at the second surface, and a bulk heat transfer device positioned in the long-stroke module, said bulk heat transfer device being in thermal contact with said surface heat transfer device to transfer heat from or to said surface heat transfer device.
