    Abstract: A lithographic apparatus, including a movable table, a projection system configured to project a patterned radiation beam onto a substrate, and a liquid supply system configured to provide liquid to a space between a final element of the projection system and the table, the liquid supply system including an inlet configured to provide liquid to the space, the inlet including an array of inlet orifices located below a bottom surface of the final element and configured to provide an essentially horizontal flow of liquid therefrom, the array of inlet orifices extending along a side of an exposure field of the patterned radiation beam, and an extractor configured to remove liquid from the space, the extractor including a two dimensional array of outlet orifices, extending at least partly in a horizontal direction, through which the liquid can be extracted from the space.
