Claim:
1. A support table for a lithographic apparatus, the support table comprising: a support section, configured to support a lower surface of a substrate on an upper face thereof; and a conditioning system, configured to supply heat energy to and/or remove heat energy from the support section; and a control system structured or programmed to control the conditioning system to supply the heat energy to and/or remove the heat energy from the support section such that there is, at least during a radiation beam exposure process applied to the substrate, heat transfer to or from the substrate per unit area of the substrate that is greater in a first region of the substrate that is adjacent the edge of the substrate and is on opposite sides of the center of the substrate for a given heat load and/or temperature change than it is in a second region of the substrate that is at a central portion of the substrate for the given heat load and/or temperature change.
