Abstract:
PROBLEM TO BE SOLVED: To provide a lithography apparatus having improved focusing ability, a method of manufacturing a device, and an exchangeable optical element. SOLUTION: A projection system PS has one or several faces PP which correspond to Fourier conjugate of an object surface at which a patterning device MA is disposed, or an image surface at which a substrate W is disposed. Such a surface is known as pupil surface. While a projection image can be usefully improved by disposing an optical element 10 in the pupil surface, the system further has an assembly in which the optical element 10 can be exchanged in the pupil surface.

Abstract:
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.
Abstract:
A lithographic apparatus has an assembly to exchange optical elements in a pupil plane of its projection system. The optical elements may be pupil filters and may conform to the physical dimensions specified for a reticle standard, e.g. having sides substantially equal to 5, 6 or 9 inches.
