ABSTRACT:
A lithographic projection apparatus is disclosed. The apparatus includes a substrate support for supporting at least one substrate, a radiation system for providing at least one beam of radiation, and a vacuum chamber. The vacuum chamber includes a patterning device and/or a projection system. The patterning device is arranged for patterning the beam of radiation according to a desired pattern, and the projection system is arranged for projecting the patterned beam of radiation onto a target portion of the substrate. The apparatus also includes at least one thermal shield for thermally conditioning at least part of the apparatus. The thermal shield includes particle transmission channels for transmitting particles through the shield, from a first side of the shield to a second side of the shield.
