Abstract:
PURPOSE: A lithography apparatus and a method for manufacturing a device are provided to control the flow of fluid through a fluid inlet by varying the flux of the fluid. CONSTITUTION: An illuminator(IL) receives a radiation beam(B) from a radiation source(SO). The illuminator includes an adjusting unit(AD) which adjusts the angular intensity distribution of the radiation beam. The radiation beam passes through a projection system(PS) and is focused on the target parts(C) on a substrate(W). A first location setting unit(PM) accurately locates a pattern device(MA). A substrate table(WT) moves to locate the target parts in the path of the radiation beam.
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus in which a barrier member is combined with a shutter member so as to keep a final element of the projection system wet during substrate swap. SOLUTION: An immersion lithographic apparatus is disclosed that includes a fluid confinement system configured to confine fluid to a space between a projection system and a substrate. The fluid confinement system includes a fluid inlet to supply fluid, the fluid inlet connected to an inlet port and an outlet port. The immersion lithographic apparatus further includes a fluid supply system configured to control fluid flow through the fluid inlet by varying the flow rate of fluid provided to the inlet port and the flow rate of fluid removed from the outlet port.

Abstract:
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

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.

PROBLEM TO BE SOLVED: To provide a liquid supply system for nailing liquid meniscus at a prescribed position in a space between a final element of a projection system and a substrate. SOLUTION: A liquid confinement system used for immersion lithography where a liquid meniscus between a liquid confinement system and a substrate is substantially nailed in a prescribed position by a meniscus nailing form is disclosed. The meniscus nailing form has a plurality of discrete outlets arranged in a polygon. COPYRIGHT: (C)2011,JPO&INPIT
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.
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.
