摘要:
A method of manufacturing a substrate holder for use in a lithographic apparatus, the method including providing a main body having a surface and a plurality of burls projecting from the surface and having end surfaces to support a substrate, providing a carrier surface adjacent the main body surface, and forming a conductive layer on at least part of the main body surface and an integral part on at least part of the carrier surface.

摘要:
A substrate holder for a lithographic apparatus has a planarization layer provided on a surface thereof. The planarization layer provides a smooth surface for the formation of an electronic component such as a thin film electronic component. The planarization layer may be provided in multiple sub layers. The planarization layer may smooth over roughness caused by removal of material from a blank to form burls on the substrate holder.
摘要:
A substrate holder for a lithographic apparatus has a planarization layer provided on a surface thereof. The planarization layer provides a smooth surface for the formation of a thin film stack forming an electronic component. The thin film stack comprises an (optional) isolation layer, a metal layer forming an electrode, a sensor, a heater, a transistor or a logic device, and a top isolation layer.
摘要:
A substrate holder for a lithographic apparatus has a main body having a thin-film stack provided on a surface thereof. The thin-film stack forms an electronic or electric component such as an electrode, a sensor, a heater, a transistor or a logic device, and has a top isolation layer. A plurality of burls to support a substrate are formed on the thin-film stack or in apertures of the thin-film stack.
摘要:
An object holder (100) for a lithographic apparatus has a main body (400) having a surface (400a). A plurality of burls (406) to support an object are formed on the surface or in apertures of a thin-film stack (410, 440, 450). At least one of the burls is formed by laser-sintering. At least one of the burls formed by laser-sintering may be a repair of a damaged burl previously formed by laser-sintering or another method.

A cover is provided for a substrate table in an immersion lithographic apparatus that covers at least the gap between a substrate and a recess in a substrate table in which the substrate is received.
摘要:
An immersion lithographic apparatus, including: first and second objects which are spaced apart with a gap therebetween and on whose top surfaces immersion liquid is provided; and a gutter positioned under the gap and configured to collect any immersion liquid which passes through the gap, wherein an advancing contact angle of immersion liquid with surfaces of the first and second objects defining the gap is less than 30°.
摘要:
A table for a lithographic apparatus, the table having a catchment opening formed in an upper surface of the table, the catchment opening in fluid communication through the table with the environment of the table at a drain opening in a surface of the table other than the upper surface.
摘要:
A lithographic apparatus, including a substrate table configured to hold a substrate; a positioner configured to position the substrate table relative to a projection system, the positioner including a short stroke module configured to perform fine positioning movements, on which the substrate table is held and which is supported on a long stroke module configured to perform coarse positioning movements; and a coverplate configured to at least partly cover a top surface of the short stroke module; wherein the coverplate is mounted to the long stroke module.
