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:
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 a reduction, if not a complete prevention, of intrusion of bubbles into a light path of a projection beam during exposure, to thereby ease defects.SOLUTION: A fluid handling structure is disclosed. The fluid handling structure is configured to confine immersion liquid to a space defined between a projection system and a facing surface facing a substrate or a space defined between the projection system and a facing surface facing a table supporting the substrate, or a space defined between the projection system and both facing surfaces. The fluid handling structure includes a transponder that melts at least a part of gas within bubbles in the immersion liquid or performs control to prevent the bubbles from intruding into a light path of a beam from the projection system.

PROBLEM TO BE SOLVED: To provide a lithographic apparatus that reduces an latent harmful influence of a droplet left on a sensor and/or a target for the sensor. SOLUTION: An immersion lithographic apparatus is disclosed that includes a table having a surface and the sensor, or the target for the 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, wherein the liquid displacement device includes a gas outlet opening configured to direct a gas flow toward the first and second areas. A property of a part of the gas flow introduced into the first area is different from a property of a part of the gas flow introduced into the second area. COPYRIGHT: (C)2011,JPO&INPIT
