Lithographic apparatus and device manufacturing method

摘要

A lithographic apparatus is disclosed wherein a liquid supply system is configured to at least partly fill a region between a substrate and a projection system of the lithographic apparatus with a liquid and having a liquid confinement structure fixed in a plane substantially perpendicular to an optical axis of the projection system and configured to cooperate with a substrate table configured to hold the substrate in order to restrict the liquid to a region above an upper surface of the substrate table so that a side of the substrate to be exposed is substantially covered in the liquid during exposure.
