Abstract:
PROBLEM TO BE SOLVED: To provide a fluid handling structure that reduces a change in refractive index and a focusing error resulting from a temperature change in a space by reducing a temperature change while in the fluid handling structure of immersion liquid provided to the space by the fluid handling structure.SOLUTION: The fluid handling structure is configured to supply and confine immersion liquid to a space defined between a projection system and a contacting surface facing to the fluid handling structure. The fluid handling structure includes a supply passage formed therein for passing fluid through the fluid handling structure from the outside to the space, and a heat insulator positioned at least partly adjacent to the supply passage in order to thermally insulate fluid in the supply passage from a heat load induced in the fluid handling structure.

PROBLEM TO BE SOLVED: To disclose a seal between a table and a component in a lithographic apparatus. SOLUTION: The seal straddles a gap between a component and a table when the component is disposed at a certain position relative to the table. The component is moveable relative to the table when in use, and in are embodiment, it is fixed to the table. The seal can be integrated with the component or the table. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide: an apparatus which can remove droplets and/or a thin film from the surface of a substrate more effectively, and a gas knife device improved in performance. SOLUTION: In an immersion lithographic apparatus, for instance, a droplet removing device uses an inclined gas flow from a gas knife during exposure to remove droplets from the substrate.

Abstract:
PROBLEM TO BE SOLVED: To provide an immersion lithographic apparatus by which a two-phase flow can be stabilized and/or at least substantially separated into liquid and gas flows, and desirably substantially minimized.SOLUTION: In order to allow a liquid-rich flow to preferentially flow along a surface, gas of a two-phase flow is more easily diverted and enters a dry chamber 127 via a gap between a divider 124 and a second wall 123. The width of a channel 125, as well as a surface coating thereon if desired, encourages the liquid to enter and the gas not to enter.
Abstract:
PROBLEM TO BE SOLVED: To provide a substrate table that can reduce or eliminate the effects of a thermal load in order to avoid deformation (e.g., expansion or contraction) of a substrate and/or substrate table.SOLUTION: There is provided a substrate table to support a substrate on a substrate supporting area, the substrate table having a heat transfer fluid channel at least under the substrate supporting area, and a plurality of heaters and/or coolers to thermally control the heat transfer fluid in the channel at a location under the substrate supporting area.
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus that combines a barrier member with a shutter member to keep the final element of a projection system wet during the replacement of a substrate. SOLUTION: A liquid immersion lithographic apparatus includes a fluid confinement system for confining a fluid in a space between the projection system and a substrate. The liquid confinement system includes an inlet port to supply liquid, and a fluid entrance connected to an outlet port. The liquid immersion lithographic apparatus further includes a fluid supply system to control the fluid flow passing through the fluid entrance by changing a flow rate of fluid supplied to the entrance port and a flow rate of fluid removed from the outlet port.

Abstract:
PROBLEM TO BE SOLVED: To provide a lithography device which is properly protected against negative effect from ultraviolet radiation and/or immersion liquid, for example. SOLUTION: A lithography device having a detachable sticky film with 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. A film with coating exists on at least part of the liquid confinement structure. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide fluid handling structure where size and constitution of a fluid extraction opening are designated in order to reduce vibration transmitted to the fluid handling structure as result of two-phase extraction.SOLUTION: The area of respective fluid extraction openings, the total area of all fluid extraction openings, and/or an interval between adjacent fluid extraction openings can be controlled. When vibration decreases, precision in exposure is improved.
Abstract:
PROBLEM TO BE SOLVED: To provide a seal between a table and a component in a lithographic apparatus.SOLUTION: 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:
PROBLEM TO BE SOLVED: To provide an apparatus by which two-phase flow can be stabilized and/or at least substantially separated into liquid and gas flows, and desirably substantially minimized. SOLUTION: 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.
