Abstract: Liquid is supplied to a space between the projection system and the substrate by an inlet. In an embodiment, an overflow region removes liquid above a given level. The overflow region may be arranged above the inlet and thus the liquid may be constantly refreshed and the pressure in the liquid may remain substantially constant.

Abstract: A process and apparatus for separating at least part of a gaseous product from a feed stream which comprises contaminants. The process comprises: 1) providing the feed stream; 2) cooling the feed stream to a temperature at which a slurry stream is formed which comprises solid contaminant, liquid phase contaminant and the gaseous product; 3) introducing the slurry stream as obtained in step 2) via a plurality of tangentially directed inlet means into an upper part of a separation device, thereby creating a swirl of the slurry stream which allows at least part of the gaseous product to flow upwardly and solid contaminant and liquid phase contaminant to flow downwardly; 4) removing at least part of the gaseous product from the upper part of the device; and 5) removing a stream comprising liquid phase contaminant from a lower part of the device.

Abstract: In a lithographic projection apparatus, a structure surrounds a space between the projection system and a substrate table of the lithographic projection apparatus. A gas seal is formed between said structure and the surface of said substrate to contain liquid in the space.

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.

Abstract: A transformer has a toroidal core with an opening therein and a plurality of wires to define a central winding section, a plurality of outer twisted wire sections and a plurality of wire proximity sections positioned between each outer twisted wire section and the central winding section. The central winding section includes a plurality of wires wrapped around the toroidal core and coupling a conductor of a primary side of a transformer and a conductor of a secondary side of a transformer. Each outer twisted wire section includes at least a pair of wires twisted together in a predetermined twisted pattern that are electrically connected to but spaced from the central winding section. The wire proximity section is configured to maintain physical proximity between the conductor of the primary side of the transformer and the conductor of the secondary side of the transformer.

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: A non-leaching adhesive system and its use in a liquid immersion objective for immersion-writing of masters for optical discs are disclosed. The adhesive system comprises at least one monomer, selected from among the group of acrylate and methacrylate monomers, allylic monomers, norbornene monomers, hybrid monomers thereof, containing chemically different polymerizable groups, and multifunctional thiol monomers, provided that said thiol is used in combination with at least one of said non-thiol monomers; and a polymerization initiator. At least one of said monomers, not being a thiol, is provided with at least two functional polymerizable groups to obtain a crosslinked polymer network. The polymerization initiator is preferably an initiator that can be activated both thermally and with UV radiation. The adhesive system may further contain a reactive diluent. Further the use of the present adhesive system in mounting a liquid immersion objective is disclosed.

Abstract: An imprinting method is disclosed that includes applying an imprinting force to a template to cause the template to contact an imprintable medium on a target region of a first surface of a substrate to form an imprint in the medium, during application of the imprinting force, applying a compensating force to a second surface of the substrate which is opposite to the first surface so as to reduce deformation of the substrate caused by the application of the imprinting force, and separating the template from the imprinted medium.

Abstract: An imprinting method is disclosed that involves, in an embodiment, redistributing a volume of imprintable medium in a flowable state over a target portion of a surface of a substrate into regions of differing volume corresponding to regions of differing pattern density of an imprint pattern of a template, contacting the medium while in the flowable state with the template to form the imprint pattern in the medium, subjecting the medium to conditions to change the medium into a substantially non-flowable state, and separating the template from the medium while in the substantially non-flowable state.

Abstract: A liquid supply system for an immersion lithographic projection apparatus is disclosed in which a space is defined between the projection system, a barrier member and a substrate. The barrier member is not sealed such that, during use, immersion liquid is allowed to flow out the space and between the barrier member and the substrate.

Abstract: An immersion lithographic apparatus includes a voltage generator or power source that applies a potential difference to an object in contact with the immersion liquid such that bubbles and/or particles in the immersion liquid are either attracted or repelled from that object due to the electrokinetic potential of the surface of the bubble in the immersion liquid.
