摘要:
A substrate table configured to support a substrate for exposure in an immersion lithographic apparatus, the substrate table including: a support body having a support surface configured to support the substrate; and a cover ring fixed relative to the support body and configured to surround, in plan view, the substrate supported on the support surface, wherein the cover ring has an upper surface, wherein at least a portion of the upper surface is configured so as to alter the stability of a meniscus of immersion liquid when moving along the upper surface towards the substrate.
摘要:
A support apparatus for a lithographic apparatus has an object holder and an extraction body radially outward of the object holder. The object holder is configured to support an object. The extraction body includes an extraction opening configured to extract fluid from a top surface of the support apparatus. The extraction body is spaced from the object holder such that the extraction body is substantially decoupled from the object holder. The extraction body comprises a projection configured such that it surrounds the object holder and such that, in use, a layer of liquid is retained on the projection and in contact with an object supported on the object holder.
摘要:
A lithographic apparatus includes a substrate table, a post-exposure handling module, a substrate handling robot and a drying station. The substrate table is configured to support a substrate for an exposure process. The post-exposure handling module is configured to handle the substrate post-exposure. The substrate handling robot is configured to transfer the substrate from the substrate table along a substrate unloading path into the post-exposure handling module. The drying station is configured to actively remove liquid from a surface of the substrate. The drying station is located in the substrate unloading path. The drying station is located in the post-exposure handling module. The post-exposure handling module may be a substrate handler.
摘要:
A component for a lithography tool, the component including a member having a primary surface; a conduit defined within the member and configured to receive a fluid under pressure; a compressible region within the member and located between the conduit and the primary surface; and a deformable region between the compressible region and the conduit, wherein the compressible region and the deformable region are configured to accommodate local deformation of the member resulting from the pressure of the fluid.

摘要:
A method of manufacturing an object holder for use in a lithographic apparatus, the object holder including one or more electrically functional components, the method including: using a composite structure including a carrier sheet different from a main body of the object holder and a layered structure including one or a plurality of layers and formed on the carrier sheet; connecting the composite structure to a surface of the main body such that the layered structure is between the carrier sheet and the surface of the main body; and removing the carrier sheet from the composite structure, leaving the layered structure connected to the main body.
摘要:
A substrate holder (WT) for use in a lithographic apparatus and configured to support a substrate (W), the substrate holder comprising: • a main body (21) having a main body surface (22); • a plurality of burls (20) projecting from the main body surface to support the substrate spaced apart from the main body surface; and • a liquid control structure (200) provided in a peripheral region (22a) of the main body surface and configured to cause liquid to preferentially flow toward the periphery of the main body surface.
