Abstract: 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.

Abstract: A substrate table of an immersion lithographic apparatus is disclosed which comprises a barrier configured to collect liquid. The barrier surrounds the substrate and is spaced apart from the substrate. In this way any liquid which is spilt from the liquid supply system can be collected to reduce the risk of contamination of delicate components of the lithographic projection apparatus.

Abstract: An immersion lithographic projection apparatus is disclosed in which liquid is provided between a projection system of the apparatus and a substrate. The use of both liquidphobic and liquidphilic layers on various elements of the apparatus is provided to help prevent formation of bubbles in the liquid and to help reduce residue on the elements after being in contact with the liquid.

Abstract: A lithographic projection apparatus is disclosed in which a space between the projection system and the substrate is filled with a liquid. An edge seal member at least partly surrounds the substrate or other object on a substrate table to prevent liquid loss when edge portions of the substrate or other object are, for example, imaged or illuminated. A lithographic projection apparatus includes a support structure configured to hold a patterning device, the patterning device configured to pattern a beam of radiation according to a desired pattern; a substrate table configured to hold a substrate; a projection system configured to project the patterned beam onto a target portion of the substrate; a liquid supply system configured to provide liquid to a space between the projection system and the substrate; and a shutter configured to isolate the space from the substrate or a space to be occupied by a substrate.

Abstract: A projection system (PS1) for a lithographic apparatus comprises: an optical path (100); a plurality of sensors (S1-S4); one or more actuators (A1-A4); and a controller (CN). The optical path is operable to receive an input radiation beam (Bin) and to project an output radiation beam (Bout) onto a substrate to form an image. The optical path comprises: a plurality of optical elements (M1-M4), the plurality of optical elements comprising: a first set of at least two optical elements (M1, M4) and a second set of at least one optical element (M2, M3). Each sensor is associated with one of the plurality of optical elements and is operable to determine a position of that optical element. Each actuator is associated with one of the second set of optical elements and is operable to adjust that optical element. The controller is operable to use the one or more actuators to adjust the second set of optical elements in dependence on the determined position of the first set of optical elements so as to at least partially compensate for optical aberrations and/or line-of-sight errors caused by the positions of the first set of optical elements.

Abstract: 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.
