摘要:
An object holder for a lithographic apparatus has a main body having a surface. A plurality of burls to support an object are formed on the surface or in apertures of a thin-film stack. 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.
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 lithographic apparatus comprising a projection system configured to project a patterned radiation beam to form an exposure area on a substrate held on a substrate table, the lithographic apparatus further comprising a cooling apparatus (40) for cooling the substrate, wherein the cooling apparatus comprises a cooling element (42, 44) located above the substrate table and adjacent to the exposure area, the cooling element being configured to remove heat from the substrate.
摘要:
An object table to support an object, the object table having a support body, an object holder to hold an object, an opening adjacent an edge of the object holder, and a channel in fluid communication with the opening via a passageway, wherein the channel is defined by a first material which is different to a second material defining the passageway.

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 planarization layer is of substantially uniform thickness and/or its outer surface has a peak to valley distance of less than 10 μm. The planarization layer may be formed by applying two solutions of different concentration. A surface treatment may be applied to the burls to repel a solution of the planarization layer material.
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.

An object holder for a lithographic apparatus has a main body having a surface. A plurality of burls to support an object is formed on the surface or in apertures of a thin-film stack. At least one of the burls is formed by laser-sintering. At least one of the burs formed by laser-sintering may be a repair of a damaged burl previously formed by laser-sintering or another method.
摘要:
A table for a lithographic apparatus, the table having an encoder plate located on the table, a gap between the encoder plate and a top surface of the table, the gap located radially inward of the encoder plate relative to the periphery of the table, and a fluid extraction system with an opening in the surface of the gap to extract liquid from the gap.
