Abstract:
An object holder for a lithographic apparatus has a main body having a surface. A plurality of burls to support an object is formed on the surface or in apertures of a thin-film stack. At least one of the burls is formed by laser-sintering. At least one of the burls formed by laser-sintering may be a repair of a damaged burl previously formed by laser-sintering or another method.
Abstract:
A lithographic projection apparatus is disclosed in which a liquid supply system provides a liquid between the projection system and the substrate. An active drying station is provided to actively remove the liquid from the substrate W or other objects after immersion of all or part of a surface of the substrate W or other objects.
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:
An object holder (100) for a lithographic apparatus has a main body (400) having a surface (400a). A plurality of burls (406) to support an object are formed on the surface or in apertures of a thin-film stack (410, 440, 450). At least one of the burls is formed by laser-sintering. At least one of the burls formed by laser-sintering may be a repair of a damaged burl previously formed by laser-sintering or another method.

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 system for positioning, a stage system, a lithographic apparatus, a method for positioning and a method for manufacturing a device in which use is made of a stage system that includes a plurality of gas bearing devices. Each gas bearing device includes: a gas bearing body, which has a free surface, a primary channel which extends through the gas bearing body and has an inlet opening in the free surface, a secondary channel system which extends through the gas bearing body and which has a plurality of discharge openings in the free surface. The flow resistance in the secondary channel system is higher than the flow resistance in the primary channel.
Abstract:
A fluid handling structure for a lithographic apparatus is disclosed. The fluid handling structure has a plurality of openings arranged in plan, in a line. The fluid handling structure is configured such that the openings are directed, in use, towards a facing surface, the facing surface being a substrate and/or a substrate table. The substrate table is configured to support the substrate. Outward of the line of openings is a damper. The damper may have a width that varies along the line of openings. The damper width is defined between the line of openings and an opposing damper edge.
Abstract:
An immersion lithographic apparatus has adaptations to prevent or reduce bubble formation in one or more gaps in the substrate table by preventing bubbles escaping from the gap into the beam path and/or extracting bubbles that may form in the gap.
