CPC classification number: G03F7/70341
Abstract: An immersion lithography apparatus is disclosed in which liquid is supplied to a space between a projection system and a substrate, and a plate structure is provided to divide the space into two parts. The plate structure has an aperture to allow transmission of the projection beam, has through holes in it to reduce the damping effect of the presence of the plate and optionally has one or more inlets and outlets to provide various flows around the aperture in the plate. An embodiment of the invention may reduce the transportation of contaminants, stray light, temperature gradients, and/or the effect of bubbles on the imaging quality.

Abstract: A lithographic apparatus comprises a substrate table for accommodating a substrate; a projection system for imaging a pattern onto the substrate, and a metrology system for measuring a position of the substrate table with respect to the projection system. The metrology system comprises a metrology frame connected to the projection system, a grid positioned stationary with respect to the metrology frame, and an encoder connected to the substrate table and facing the grid for measuring the position of the substrate table relative to the grid. The metrology frame has a surface oriented towards the substrate table, and the surface has been configured, e.g., by writing or etching, so as to form the grid.

Abstract: A lithographic apparatus component, such as a metrology system or an optical element (e.g., a mirror) is provided with a temperature control system for controlling deformation of the component. The control system includes channels provided close to a surface of the component through which a two phase cooling medium is supplied. The metrology system measures a position of at least a moveable item with respect to a reference position and includes a metrology frame connected to the reference position. An encoder is connected to the moveable item and constructed and arranged to measure a relative position of the encoder with respect to a reference grid. The reference grid may be provided directly on a surface of the metrology frame. A lithographic projection apparatus may have the metrology system for measuring a position of the substrate table with respect to the projection system.

Abstract: In a lithographic projection apparatus, a liquid supply system maintains liquid in a space between a projection system of the lithographic projection apparatus and a substrate. A sensor positioned on a substrate table, which holds the substrate, is configured to be exposed to radiation when immersed in liquid (e.g., under the same conditions as the substrate will be exposed to radiation). By having a surface of an absorption element of the sensor, that is to be in contact with liquid, formed of no more than one metal type, long life of the sensor may be obtained.

Abstract: 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.
