摘要： An immersion lithographic apparatus is disclosed having comprising a pump and buffer volume configured to remove remaining liquid from a substrate, the pump and the buffer volume configured to generate a vacuum cleaning gas flow near the substrate by gas suction into the buffer volume. In an embodiment, since gas flow is needed only a limited amount of time (ordinarily less than 5%), evacuation may be performed using only a moderately powered vacuum pump. In addition or alternatively, the buffer volume may be used as a backup volume buffer configured to provide gas vacuum suction, e.g., in case of a vacuum supply outage.

摘要： A lithographic apparatus is disclosed. The apparatus includes an illumination system to provide a beam of radiation, and a support structure for supporting a patterning device. The patterning device serves to impart the beam with a pattern in its cross-section. The apparatus also includes a gas flushing device for flushing a substantially laminar flow of gas across the beam of radiation and/or along a surface of an optical component. The gas flushing device includes a single gas outlet that has an inner rim at a downstream end of the gas outlet. The inner rim defines a total gas outlet area. The gas outlet is provided with a laminator that has an effective area out of which, in use, the substantially laminar flow of gas flows. The laminator effective area includes material that has laminator openings and is at least as large as the total gas outlet area.
