Abstract:
1. A lithographic immersion exposure apparatus which exposes a substrate with a patterned beam of radiation via a projection system and a liquid, the apparatus comprising: a first table connected to a first table drive system that drives the first table in a direction to displace the first table into and out of a path of the patterned beam of radiation, the first table having a substrate holder to hold the substrate; and a second table connected to a second table drive system that drives the second table to displace the second table into the path of the patterned beam of radiation when the first table is displaced out of the path of the patterned beam of radiation, the second table not being configured to hold any substrate, the first and second tables are movable relative to each other in the direction, the second table drive system positioning the second table adjacent to the first table, the first and second table drive systems causing the adjacent first and second tables to be moved together relative to the projection system in the direction so that the liquid is relatively moved from the first table to the second table and so as to place the second table into the path of the patterned beam of radiation while the first table is being displaced out of the path of the patterned beam of radiation.
