摘要:
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.
摘要:
An immersion lithographic apparatus is disclosed that includes a table having a surface and a sensor, or a target for a sensor, or both, the sensor and/or target having a first area which is lyophobic to immersion liquid and a second area which is lyophilic to immersion liquid, and a liquid displacement device configured to displace liquid on the sensor and/or target, the liquid displacement device comprising a gas outlet opening configured to direct a gas flow toward the first and second areas, wherein a property of a part of the gas flow directed to the first area is different to a property of a part of the gas flow directed to the second area.
摘要:
A substrate table for an immersion lithographic apparatus is disclosed having a recess, configured to receive a substrate of a given size, and a fluid extraction system, configured to extract fluid from a gap between the edge of the substrate and the edge of the recess, the fluid extraction system configured such that the rate of flow of fluid extracted from a localized section of the gap is greater than the rate of flow of fluid extracted from another section of the gap.
摘要:
A fluid handling structure and lithographic apparatus is disclosed in which measures are taken, in particular to the dimensions and spacing of an array of openings in a bottom surface of the fluid handling structure, to deal with and/or prevent formation of bubbles in immersion liquid.
摘要:
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.

摘要:
A fluid handling structure to confine immersion liquid in a space between a projection system and a facing surface of a substrate, of a table to support the substrate, or both, is disclosed. The fluid handling structure includes a transponder to dissolve at least some of the gas in a bubble in the immersion liquid or to control a bubble in the immersion liquid so that it avoids entering an optical path of a beam from the projection system.
摘要:
A fluid handling structure is disclosed in which measures are taken to increase the speed at which meniscus breakdown occurs. Measures include the shape of a plurality of fluid extraction openings and the shape and density of a plurality of fluid supply openings in the fluid handling structure.
摘要:
A lithographic apparatus is disclosed having a removable adhesive film carrying a coating on at least a part of the apparatus. In an embodiment, a liquid supply system having a liquid confinement structure extending along at least part of a boundary of a space between a projection system and a substrate support is disclosed, wherein the film carrying the coating is on at least part of the liquid confinement structure.
