    Abstract: An x-ray optical system includes a multiple corner optic assembly including an adjustable aperture assembly located in close proximity to the optic assembly. The adjustable aperture assembly enables a user to easily and effectively adjust the convergence of an incident beam of x-rays or the optic focal spot size. The adjustable aperture assembly may further enable a user to condition x-rays of one wavelength and block x-rays of another wavelength and thereby reduce the amount of background radiation exhibited from x-rays of more than one wavelength.

    Abstract: A multilayer mirror (100) is configured to reflect extreme ultraviolet (EUV) radiation while absorbing a second radiation having a wavelength substantially- longer than that of the EUV radiation. The mirror includes a plurality of layer pairs (110, 112) stacked on a substrate (104). Each layer pair comprises a first layer (112) that includes a first material, and a second layer (110) that includes a second material. The first layer (112) is modified to reduce its contribution to reflection of the second radiation, compared with a simple layer of the same metal having the same thickness. Modifications can include doping with a third material in or around the metal layer to reduce its electric conductivity by chemical bonding or electron trapping, and/or splitting the metal layer into sub-layers with insulating layers. The number of layers in the stack is larger than known multilayer mirrors and may be tuned to achieve a minimum in IR reflection.

    Abstract: A transmissive spectral purity filter configured to transmit extreme ultraviolet radiation includes a filter part having a plurality of apertures to transmit extreme ultraviolet radiation and to suppress transmission of a second type of radiation. The apertures may be manufactured in semiconductor material such as silicon by an anisotropic etching process. The semiconductor material is provided with a hydrogen-resistant layer, such as silicon nitride Si 3 N 4 , silicon dioxide SiO 2 , or silicon carbide SiC. Roughness features may be exaggerated in the sidewalls of the apertures. The filter part may be less than about 20 μm thick with apertures about 2 μm to about 4 μm in width.

    Abstract: In order to produce stress-reduced reflective optical elements (1) for an operating wave length in the soft X-ray and extreme ultraviolet wavelength range, in particular for use in EUV lithography, it is proposed to apply between substrate (2) and a multilayer system (4) optimized for high reflectivity at the operating wavelength a stress-reducing multilayer system (6) with the aid of layer-forming particles, having an energy of 40 eV or more preferably 90 eV or more. Resulting reflective optical elements (1) are distinguished by low surface roughnesses, a low number of periods in the stress-reducing multilayer system and also high Γ values of the.stress-reducing multilayer system.

    Abstract: Un collecteur de rayonnement (10) est adapté pour concentrer dans une tache (100) une partie d'un rayonnement produit par une source. Le collecteur comprend un miroir primaire concave (1) et un miroir secondaire convexe (2), chacun à symétrie de révolution autour d'un axe optique (X-X) du collecteur. Le miroir primaire est adapté pour réfléchir le rayonnement collecté avec un angle d'incidence (i) qui est sensiblement constant entre des points différents dudit miroir primaire. Un tel collecteur est particulièrement adapté pour être utilisé avec une source du type plasma produit par décharge.
