Abstract:
1. A lithographic projection apparatus, comprising: an illumination system arranged to condition a radiation beam; a support structure configured to hold a patterning device, the patterning device being capable of imparting the radiation beam with a pattern; a substrate table configured to hold a substrate; a projection system arranged to project the patterned radiation beam onto a target portion of the substrate; a liquid supply system configured to at least partly fill a space, between the projection system and the substrate table, with a liquid; and a substrate positioner configured to move the substrate out of contact with a substrate table surface, the substrate positioner being adapted to initially exert a resultant force on the substrate that is offset from the center of the substrate so as to overcome a tendency of liquid, from the liquid supply system, between the substrate and substrate table surface to cause the substrate to stick to the substrate table surface.
