摘要： A method for filtering a fluid to obtain a fluid having a known purity is described. The fluid is filtered with a filtration system, and upstream of a final filtration stage of the filtration system, a purity of the fluid is measured. A purity of the fluid filtered by the filtration system is determined by correcting the measured purity with a filtration behavior of the final filtration stage. In an embodiment, the fluid comprises an ultra pure water for use as an immersion liquid in a lithographic apparatus.

摘要： In a lithographic projection apparatus, there is provided a liquid supply system comprising a container at least partly defining a space between the projection system and the substrate, the container having a selectively openable and closeable aperture therein, and a closure configured to selectively close and open the aperture. In an embodiment, the shutter may comprise a channel in a surface of the shutter facing the aperture and/or the shutter may be displaced from the liquid supply system when connected to the liquid supply system. Further, in a lithographic apparatus, there is provided a liquid supply system configured to provide a liquid, through which the beam is to be projected, in a space between a projection system and a substrate and a controller configured to control application to the projection system of a force related to a weight transfer attributable to a member of the liquid supply system.

摘要： Various types of pressure regulating devices are disclosed to reduce a pressure gradient in a liquid supply system of a lithographic apparatus, the liquid supply system having a liquid confinement structure configured to at least partially confine a liquid between a projection system and a substrate table of the lithographic apparatus. A high pressure gradient may cause particulate contamination in the liquid supply system and/or liquid confinement structure. A pressure gradient can be reduced by, for example, the use of slow switching in one or more valves, a bleed flow around or through one or more valves, diversion of liquid to a drain rather than or in addition to switching a valve off, a pressure regulator or flow restrictor to prevent shock waves, and a buffer volume/damper to compensate for pressure fluctuation.

摘要： An immersion lithographic apparatus is provided with a liquid confinement structure which defines at least in part a space configured to contain liquid between the projection system and the substrate. In order to reduce the crossing of the edge of the substrate which is being imaged (which can lead to inclusion of bubbles in the immersion liquid), the cross-sectional area of the space in a plane parallel to the substrate is made as small as possible. The smallest theoretical size is the size of the target portion which is imaged by the projection system. In an embodiment, the shape of a final element of the projection system is also changed to have a similar size and/or shape in a cross-section parallel to the substrate to that of the target portion.

摘要： A lithographic projection apparatus is disclosed in which measures are taken to prevent or reduce the presence of bubbles in liquid through which the projection beam radiates. This may be done, for example, by ensuring that a gap between a substrate and a substrate table is filled with immersion liquid or by causing a localized flow radially outwardly from the optical axis in the vicinity of the edge of the substrate.

摘要： In a lithographic projection apparatus, a liquid supply system maintains liquid in a space between the projection system and the substrate. The liquid supply system may further include a de-mineralizing unit, a distillation unit, a de-hydrocarbonating unit, a UV radiation source, and/or a filter configured to purify the liquid. A gas content reduction device may be provided to reduce a gas content of the liquid. A chemical may be added to the liquid using an adding device to inhibit lifeform growth and components of the liquid supply system may be made of a material which is non-transparent to visible light such that growth of lifeforms may be reduced.
