Abstract:
A support table for a lithographic apparatus, a method of loading a substrate, a lithographic apparatus and a method for manufacturing a device using a lithographic apparatus. In one arrangement, a support table is configured to support a substrate. The support table has a base surface. The base surface faces a surface of the substrate when the substrate is supported by the support table. One or more gas cushion members are provided above the base surface. Each of the gas cushion members includes a recess. The recess is shaped and configured such that a lowering of the substrate into a position on the support table at which the substrate is supported by the support table causes a localised build-up of pressure within the recess. The localized build-up of pressure provides a localised gas cushioning effect during the lowering of the substrate.
