摘要:
A composite structure for microlithography, in particular a holding device for a wafer, has two or more components, the surfaces of which are bonded together at least at one bond. At least one of the components consists of cordierite (Mg2Al4Si5O18) or of silicon carbide (SiC). Also disclosed is an optical arrangement, in particular a projection illumination apparatus for microlithography, having at least one such composite structure, preferably a wafer stage.
摘要:
A microlithographic projection exposure apparatus contains an illumination system for generating projection light and a projection lens with which a reticle that is capable of being arranged in an object plane of the projection lens can be imaged onto a light-sensitive layer that is capable of being arranged in an image plane of the projection lens. The projection lens is designed for immersion mode, in which a final lens element of the projection lens on the image side is immersed in an immersion liquid. A terminating element that is transparent in respect of the projection is fastened between the final lens element on the image side and the light-sensitive layer.

An imaging device in a projection exposure machine for microlithography includes at least one optical element and at least one manipulator, a linear drive for manipulating the position of the optical element. The linear drive has at least one moving element, the moving element having a shearing part and a lifting part. The shearing part is arranged to move the optical element and the lifting part is arranged to move the shearing part. The linear drive has a supporting element which is in contact with and prevents movement of the optical element while the shearing part is moved by the lifting part.

In an apparatus for mounting two or more optical elements that are each held in an individual mount or in a support structure, said optical elements are mounted in a common mount. The relative positioning of the optical elements (10, 11) in the common mount (18) can be set.
摘要:
The invention relates to a method for connection of an optical element to a mount structure, whereby in a first step the optical element is connected to the mount structure and in a second step the optical element is welded to the mount structure in the region of the connection.
摘要:
A catadioptric lens with optical elements, which are arranged along an optical axis and with at least one concave mirror located in the vicinity of a pupillar surface of the projection lens. The concave mirror is sub-divided into a number of annular or honeycomb mirror segments, which can be displaced independently in relation to one another with the aid of piezoelectric drive elements. The mirror can be used as a phase-shifting pupillar filter, whereby the filtration function can be adjusted by the relative displacement of the mirror elements in relation to one another.
摘要:
There is provided a support structure for temporarily supporting a substrate in a support di-reaction during one of treatment and handling of the substrate comprising a base structure and at least one layer connected to the base structure. The at least one layer defines at least one protrusion of the support structure, the at least one protrusion being adapted to contact the substrate when the substrate is supported by the support structure. The at least one layer comprises a wear resistant material.
