Abstract: A liquid confinement system for use in immersion lithography is disclosed in which the meniscus of liquid between the liquid confinement system and the substrate is pinned substantially in place by a meniscus pinning feature. The meniscus pinning feature comprises a plurality of discrete outlets arranged in a polygonal shape.

Abstract: A substrate table for an immersion lithographic apparatus is disclosed having a recess, configured to receive a substrate of a given size, and a fluid extraction system, configured to extract fluid from a gap between the edge of the substrate and the edge of the recess, the fluid extraction system configured such that the rate of flow of fluid extracted from a localized section of the gap is greater than the rate of flow of fluid extracted from another section of the gap.

Abstract: An immersion lithographic apparatus includes a projection system. The projection system is configured to project a patterned radiation beam through an immersion liquid onto a target portion of a substrate. An external surface of the projection system includes a first surface. The first surface has a non-planar shape. An element is attached to the first surface and positioned so that at least a portion of the element contacts the immersion liquid in use. The element includes a closed loop of continuously integral material in a preformed state and conforms to the non-planar shape of the first surface.

Abstract: An immersion lithographic apparatus is described in which a two-phase flow is separated into liquid-rich and gas-rich flows by causing the liquid-rich flow to preferentially flow along a surface.

Abstract: A seal between a table and a component in a lithographic apparatus is disclosed. The seal bridges a gap between the component and the table when the component is in a position relative to the table. The component is moveable, in use, relative to the table and in an embodiment is attached to the table. The seal may be integral with the component or the table.

Abstract: An immersion lithographic apparatus is disclosed that includes a table having a surface and a sensor, or a target for a sensor, or both, the sensor and/or target having a first area which is lyophobic to immersion liquid and a second area which is lyophilic to immersion liquid, and a liquid displacement device configured to displace liquid on the sensor and/or target, the liquid displacement device comprising a gas outlet opening configured to direct a gas flow toward the first and second areas, wherein a property of a part of the gas flow directed to the first area is different to a property of a part of the gas flow directed to the second area.

Abstract: A fluid handling structure to confine immersion liquid in a space between a projection system and a facing surface of a substrate, of a table to support the substrate, or both, is disclosed. The fluid handling structure includes a transponder to dissolve at least some of the gas in a bubble in the immersion liquid or to control a bubble in the immersion liquid so that it avoids entering an optical path of a beam from the projection system.
