Abstract:
1. A lithographic apparatus comprising: a projection system configured to project a beam of radiation onto a substrate; a first table configured to support a substrate; a second table, not being configured to support a substrate, comprising a sensor unit configured to sense a property of a beam of radiation from the projection system; a liquid supply system configured to supply a liquid to a space between the projection system and the substrate; a sensor system configured to measure a height of the substrate on the first table and/or measure the position of an alignment marker of the substrate on the first table, the sensor system located at a first side of a path traversed by the beam of radiation; and a controller configured to control positioning of the second table from in the path to a position out of the path at a second side opposite the first side in synchronism with displacement of the first table into the path.
