Abstract:
PURPOSE: A lithographic apparatus having parts with a coated film adhered thereto is provided top protect a negative effect from an UV radiation and an immersion fluid by supporting the coating on at least part of lithography apparatus. CONSTITUTION: A lighting system(IL) conditions radiation beam. A patterning device supporter(MT) supports a patterning device(MA). A substrate supporter supports the substrate. A projection system(PS) projects the patterned radiation beam on the target on the substrate. The adhesive film supports the coating on at least part of a lithography apparatus.
Abstract:
PROBLEM TO BE SOLVED: To provide an immersion lithography system which can determine a maximum relative speed which can sufficiently confirm the fact that the loss of an immersion fluid is reduced to its allowable minimum level and can be configured not to exceed the speed. SOLUTION: The immersion lithography system determines an allowable maximum speed of a substrate with respect to an immersion-liquid trapping structure controlling the immersion liquid on the basis of characteristics of the exposure target substrate, and limits the speed of the substrate to the liquid trapping structure to the allowable maximum speed or below during an exposure process.

PROBLEM TO BE SOLVED: To provide a fluid handling system which maintains liquid in a space between a final element of a projection system and a substrate.SOLUTION: A fluid handling structure for a lithographic apparatus is disclosed, the fluid handling structure successively has, at a boundary from a space configured to contain immersion fluid to a region external to the fluid handling structure: an elongate opening or a plurality of openings arranged in a first line that, in use, are directed towards a substrate and/or a substrate table configured to support the substrate; a gas knife device having an elongate aperture arranged in a second line; and an elongate opening or a plurality of openings adjacent to the gas knife device.
Abstract:
PROBLEM TO BE SOLVED: To reduce generation of bubbles in an immersion liquid and evaporation of the liquid. SOLUTION: An immersion lithographic apparatus includes a liquid containment structure 12 provided for at least partially defining a space 10 structured to contain a liquid between a projection system PL and a substrate W. A sectional area of the space 10 in a plane parallel to the substrate W is minimized to reduce a traverse of a rim of the substrate W whose image is to be formed (which sometimes brings a content of bubbles in the immersion liquid). The theoretically minimum size is that of a target part TP whose image is to be formed by the projection system PL. In addition, in one embodiment, a shape of a final element of the projection system PL is modified to have a size and/or a shape similar to the target part TP on a cross section parallel to the substrate W.

Abstract:
PROBLEM TO BE SOLVED: To make it possible to suppress deterioration of removable members. SOLUTION: A member is provided to prevent immersion liquid ingress to a gap between components or to adhere to at least one component to provide a surface to a feature of an immersion system. The member has a plastic sealing portion that is adhered to the component(s). The plastic sealing portion is opaque to DUV radiation. The plastic sealing portion may be resistant to degradation through exposure to DUV radiation. The plastic sealing portion may have a liquid phobic coating or property. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
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 a lithographic projection apparatus in which measures are taken to prevent or reduce presence of bubbles in liquid through which radiated projection beam passes.SOLUTION: This provision may be done, for example, by ensuring that a gap between a substrate and a substrate table is filled with immersion liquid or by causing a localized flow toward radial outside direction from an optical axis in the vicinity of an edge of the substrate.
Abstract:
PROBLEM TO BE SOLVED: To provide an immersion lithographic apparatus, in which temperature gradient in an immersion liquid is reduced or avoided.SOLUTION: An immersion lithographic apparatus, arranged in a space where one or a plurality of liquid flow dividers are enclosed by a liquid confinement structure, is disclosed. A function of the liquid flow dividers is to prevent formation of one or a plurality of recycle zones of an immersion liquid which often produce change in refractive index of the immersion liquid in the space, or consequently sometimes produce mapping error.
