PROBLEM TO BE SOLVED: To provide a lithographic apparatus, and to provide a device manufacturing method. SOLUTION: A liquid supply system is configured to supply a liquid to a region between a substrate W and a projection system PL of the lithographic apparatus, and has a liquid confinement structure 12 fixed in a plane substantially perpendicular to an optical axis of the projection system PL and configured to hold the substrate W in order to restrict the liquid to a region above an upper surface of a substrate table WT so that a side of the substrate W to be exposed is substantially covered with the liquid during exposure.

Abstract:
PROBLEM TO BE SOLVED: To provide a substrate for reducing a contamination source to be used for a lithography projection device. SOLUTION: The substrate W comprises a sealing coating 106 covering at least part of a first interface between two layers 100, 102 on the substrate or between each layer and the substrate without extending to a central portion of the substrate. The sealing coating is used for providing the substrate which is used for the lithography projection device for reducing a risk of contaminating one or more components of immersion liquid and a lithography device, and a device manufacturing method.

PROBLEM TO BE SOLVED: To provide a system for reducing lithographic errors caused by immersion liquid. SOLUTION: A lithography apparatus comprises an illumination system so constituted as to control a radiation beam, a support so constituted as to support a pattern forming device which imparts patterns on a crosssection of the radiation beam to form a patternized radiation beam, a substrate table so constituted as to hold a substrate, a projection system so constituted as to project the patternized radiation beam on the target of the substrate, a liquid supply system so constituted as to fill at least part of a space between a final element of the projection system and the substrate with the liquid, a sealing member so disposed as to substantially enclose the liquid inside the space between the final element of the projection system and the substrate, and an element for controlling and/or compensate evaporation of the immersion liquid from the substrate.

Abstract:
PROBLEM TO BE SOLVED: To provide an immersion liquid containing one or more additives for solving the problem of stain appearance when drying areas wetted by the liquid in immersion exposure.SOLUTION: A device manufacturing method includes adding a component having a vapor pressure greater than 0.1 IcPa to a liquid and exposing a photosensitive substrate to radiation, in which the radiation passes through the aqueous liquid containing the component before reaching the photosensitive substrate. Since the addition of the component increases an ion concentration in the liquid, the immersion liquid is provided containing an ion-forming component, e.g. an acid or a base having a relatively high vapor pressure. Also provided are lithography processes and lithography systems using the immersion liquid.
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus, a method of controlling the same, and a device manufacturing method, wherein defects of imaging are reduced or eliminated. SOLUTION: The method includes the steps of: moving a substrate table supporting a substrate relative to a projection system; and adjusting the scanning speed between the substrate table and the projection system during imaging of a target within a predefined area at or near an edge of the substrate, and/or adjusting the stepping speed between adjacent target positions in a predefined area at or near the edge of the substrate. The step of adjusting the scanning and/or stepping speed may comprise lowering the speed. The projection system is configured to project a patterned beam of radiation onto a target portion of the substrate. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To disclose a lithographic projection apparatus that includes a table, a shutter member, a fluid handling structure, and a fluid extraction system. SOLUTION: The fluid handling structure may be configured to supply and confine liquid between a projection system and (i) a substrate, or (ii) the substrate table, or (iii) a surface of the shutter member, or (iv) an arbitrary combination selected from (i)-(iii). The surface of the shutter member may adjoin and be co-planar with a surface of the table. The surfaces of the shutter member and the table may be spaced apart by a gap. The fluid extraction system may be configured to remove liquid from the gap. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method of detecting particles in liquid immersion fluid in a lithography device or in liquid immersion fluid from the lithography device. SOLUTION: The method includes, using a vacuum system, extracting a sample from a single phase flow of liquid immersion fluid of a fluid handling structure of a lithography device or from a fluid handling structure. The method includes detecting particles in a sample, and when detected particles exceed a particular threshold, starting a signal. COPYRIGHT: (C)2010,JPO&INPIT
