  • Publication number: 20210149093
    Abstract: Substrates suitable for mirrors used at wavelengths in the EUV wavelength range have substrates (1) including a base body (2) made of a precipitation-hardened alloy, of an intermetallic phase of an alloy system, of a particulate composite or of an alloy having a composition which, in the phase diagram of the corresponding alloy system, lies in a region which is bounded by phase stability lines. Preferably, the base body (2) is made of a precipitation-hardened copper or aluminum alloy. A highly reflective layer (6) is preferably provided on a polishing layer (3) of the substrate (1) of the EUV mirror (5).

  • Patent number: 7816022
    Abstract: 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.

  • Publication number: 20070285647
    Abstract: 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.
