Abstract:
PROBLEM TO BE SOLVED: To limit the movement of immersion liquid in a gap between immersion system structure and a projection system, and to reduce the quantity of immersion liquid that escapes the immersion system through the gap.SOLUTION: A lithographic apparatus includes a projection system configured to project a patterned radiation beam onto a target portion of a substrate. The lithographic apparatus also includes a barrier member, surrounding a space between the projection system, and the substrate in use, to define in part with the projection system a reservoir for liquid. A radially outer surface of the barrier member facing a portion of the projection system and a radially outer surface of the portion of the projection system facing the barrier member each have a lyophobic outer surface. The lyophobic outer surface of the barrier member and/or the lyophobic outer surface of the portion of the projection system has an inner edge that defines in part the reservoir.

PROBLEM TO BE SOLVED: To provide a system that reduces an influence of a droplet on a final optical element, or substantially avoids the formation of such a droplet. SOLUTION: This lithography device includes: a projection system PS; and a liquid confinement structure for at least partially confining an immersion liquid in an immersion space demarcated by the projection system, a liquid confinement structure 12, and also a substrate and/or a substrate table. A wet gas space for confining a wet gas is demarcated among the projection system, the liquid confinement structure, and the immersion liquid in the immersion space. COPYRIGHT: (C)2010,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide an immersion lithographic apparatus in which an imaging error and/or focusing error of the projection system, caused by movement of the meniscus, is reduced, if not eliminated. SOLUTION: The apparatus has a projection system which is configured to project a patterned radiation beam onto a target portion of the substrate, and having a lower surface. The apparatus also has a liquid confinement structure defining, in use, in part with the lower surface and the substrate and/or substrate table, an immersion space, and the immersion space has, in use, a liquid meniscus between a part of the lower surface facing a surface of the liquid confinement structure and a facing surface of the liquid confinement structure facing the part of the lower surface. The apparatus also has a pinning surface having a plurality of meniscus pinning features, the pinning surface being part of or on the part of the lower surface, or part of or on the facing surface of the liquid confinement structure, or part of or on both.

In the lithographic apparatus, means is taken for, e.g., reducing effect of droplets on a final element of the projection system or substantially avoiding such droplet formation.
Abstract:
PROBLEM TO BE SOLVED: To provide systems and methods for providing the use of a two- or three-plate Alvarez lens located in a focal plane of a projection lens of a lithographic apparatus.SOLUTION: The Alvarez lens can be used to modify the shape of the focal plane to match a previously determined surface topography, while at the same time the Alvarez lens can be designed to include a built-in correction for astigmatism and other residual Zernike errors that would otherwise be introduced.
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid handling structure, lithographic apparatus and device manufacturing method which compensate for cooling of a substrate due to the presence of an immersion liquid.SOLUTION: The fluid handling structure is configured to confine an immersion fluid in a space between a final element of a projection system and a facing surface during movement of the facing surface relative to the structure. The structure has at least one heater to heat a portion of the facing surface adjacent to the heater. The at least one heater has a fluid heater to heat fluid flow from the structure onto the facing surface, thereby heating the portion.
