Abstract:
PURPOSE: A substrate table, an immersion lithography apparatus, and a method for manufacturing a device are provided to reduce the generation of defects on images by minimizing bubbles in the immersion lithography apparatus. CONSTITUTION: A pre-set size substrate(W) is contained in a recess(20). The recess includes a supporting region supporting the lower surface of the substrate and an edge. The edge is adjacently arranged to the edge of the substrate. A fluid draining system drains fluid from a gap(26) between the edges of the substrate and the recess. The fluid draining system includes a first duct(32) and a second duct(42) which are open toward the inside gap.
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus in which the likelihood of bubble inclusion in an immersion liquid is at least reduced.SOLUTION: A fluid handling structure for a lithographic apparatus comprises at a boundary of a space configured to contain immersion fluid to a region external to the fluid handling structure: a meniscus pinning feature to resist passage of immersion fluid in a radially outward direction from the space; a gas supply opening at least partly surrounding and radially outward of the meniscus pinning feature; and optionally a gas recovery opening radially outward of the gas supply opening. The gas supply opening, or the gas recovery opening, or both the gas supply opening and the gas recovery opening, has an open area per meter length which has a variation around the space.
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 provide a fluid handling structure for minimizing or preventing the sealing of bubbles within an immersion solution of an immersion lithographic apparatus. SOLUTION: A fluid handling structure is for a lithographic apparatus. At a boundary from a space configured to include an immersion fluid to a region external to the fluid handling structure, the fluid handling structure successively has an extractor having at least one opening arranged in a first line that, in use, is directed towards a substrate and/or a table and a liquid manipulator on a surface that, in use, faces the substrate and/or table to reduce the chance of droplets on the surface from coalescing.

Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus for preventing bubbles from entering a projection beam during image formation. SOLUTION: In a liquid confinement structure of an immersion lithographic apparatus, an elongate continuous opening forms an outlet for supplying liquid to a space beneath a projection system. The elongate slit forms a region of high shear and pressure gradient that deflects bubbles away from an image field. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To reduce a possibility or an influence of bubbling in an immersion lithographic apparatus. SOLUTION: A substrate table for an immersion lithographic apparatus has a recessed portion constituted to store a substrate of given size, and a fluid extraction system configured to extract a fluid from a gap between an edge of the substrate and an edge of the recessed portion, wherein the fluid extraction system is characterized in that the flow rate of the fluid extracted from a local part of the gap is larger than the flow rate of the fluid extracted from other parts of the gap.

Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus in which mixing of gas from and external to a fluid handling structure is at least partly reduced or prevented.SOLUTION: A fluid handling structure for a lithographic apparatus has, at a boundary of a space configured to contain immersion fluid to a region external to the fluid handling structure, a gas supply opening provided radially outward of the space, a fluid recovery opening provided radially outward of the gas supply opening, and a damper surface extending at least 0.5 mm radially outward from the fluid recovery opening along the undersurface of the fluid handling structure.
Abstract:
PROBLEM TO BE SOLVED: To provide a lithography device, for example, in which possibility of creating air bubbles is at least reduced.SOLUTION: A fluid handling structure for a lithography device has one or more meniscus nailing characteristic parts for resisting passage of a liquid-immersion fluid from a space outward in a radial direction at a boundary from a space for housing the liquid-immersion fluid to a region outside the fluid handling structure, a gas supply opening outside the one or more meniscus nailing characteristic parts in the radial direction, and at least one gas recovery opening located outside the one or more meniscus nailing characteristic parts in the radial direction and at least partially surrounding the gas supply opening.
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.
