Abstract:
1. A lithographic apparatus comprising: a substrate table constructed and arranged to hold a substrate, the substrate table having a support block having a recess therein and a thermal conditioning plate on the support block and in the recess, the thermal conditioning plate having thereon, in thermal contact, a substrate support plate in the recess, wherein the support block, the thermal conditioning plate, and the substrate support plate are separate from each other and not permanently attached to each other, the substrate support plate comprising a material having a thermal conductivity of equal to or greater than approximately 50 W/mK and a substrate support surface that defines a plurality of surface deformations arranged to contact and support the substrate, wherein the surface deformations are arranged to contact more than or equal to 5% but less than or equal to approximately 20% of the area of a surface of the substrate that is arranged to contact the substrate support surface; and a projection system constructed and arranged to project a patterned beam of radiation onto a target portion of the substrate.
