PROBLEM TO BE SOLVED: To provide a liquid supply system for hooking a liquid meniscus at a predetermined position in a space between the final element and the substrate of a projection system. SOLUTION: Disclosed is a liquid immersion system used for a liquid immersion lithography in which a liquid meniscus between the liquid immersion system and its substrate is substantially hooked at a predetermined position by meniscus hook formation. The meniscus hook formation has a plurality of discrete outlets arranged in polygonal shape. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid handling structure where a measure has been taken in order to increase a speed at which meniscus destruction arises.SOLUTION: A meniscus fixation device is provided with a plurality of separate openings 50. Although these openings 50 are each illustrated as a circle, it is not necessary to be so. The openings 50 surround a space that is a destination to which the fluid handling structure supplies a fluid. That is, the openings 50 are spaced continuously substantially on the circumference of the space. The openings 50 are arranged so that a shape having a corner (that is, a shape having a corner 52) may be formed in a plan view. This is a square shape having a curved marginal part or side 54. The marginal part 54 has a negative radius. That is, in a section apart from the corner 52, it curves toward a center of the shape having the corner.

PROBLEM TO BE SOLVED: To provide a lithography device which is properly protected from a negative effect resulting for ultraviolet radiation and/or immersion liquid, for example. SOLUTION: A lithography device having a detachable sticky film with a coating on at least part thereof is disclosed. A liquid supply system with a liquid confinement structure extended along at least part of a boundary of a space between a projection system and a substrate support is disclosed. The film with coating exists on at least part of the liquid confinement structure. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a device capable of removing undesired droplets from a surface of a substrate and/or a substrate table more effectively and efficiently. SOLUTION: A fluid handling system for an immersion lithography apparatus has a fluid removal device to remove immersion liquid from an immersion space, and a droplet removal device to remove a droplet of immersion liquid, wherein: the droplet removal device is located further from an optical axis than the fluid removal device, and the droplet removal device includes a porous member which faces, e.g., the substrate being exposed and/or the substrate table.

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
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid handling system which reduces the possibility that, for example, bubbles are formed and/or invade into a liquid immersion space. SOLUTION: In a fluid handling structure, a means for dealing with and/or preventing the formation of bubbles in a liquid immersion liquid is taken particularly in relation to the dimension and intervals of the array of the opening on the bottom surface of the fluid handling structure. A lithography apparatus is also provided. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To disclose a fluid handling structure where the size and structure of a fluid extraction opening are designated to reduce vibration transmitted to the fluid handling structure as a result of two-phase extraction. SOLUTION: The area of respective fluid extraction openings, the total area of all of the fluid extraction openings, and/or the space between adjacent fluid extraction openings can be controlled. When vibration decreases, precision in exposure is improved. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
A method of operating a lithographic apparatus is disclosed. The method includes 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, or adjusting the stepping speed between adjacent target positions in a predefined area at or near the edge of the substrate, or both. The adjusting the scanning and/or stepping speed may comprise lowering the speed. The projection system is configured to project a patterned beam of radiation on to a target portion of the substrate.
Abstract:
A fluid handling structure configured to supply and confine immersion liquid to a space defined between a projection system and a facing surface facing the fluid handling structure is disclosed. The fluid handling structure includes a supply passage formed therein for the passage of fluid from outside the fluid handling structure to the space, and a thermal isolator positioned adjacent the supply passage at least partly to isolate fluid in the supply passage from a thermal load induced in the fluid handling structure.
