Abstract: A mask having a multilayer coating of a specified period thickness distribution such as those used in lithography devices for producing semiconductor components. One problem of projection optics concerns pupil apodization which leads to imaging defects. As here proposed, the period thickness in the mask plane is selected so that it is greater than the period thickness for maximum reflectivity. As a result, not only does the apodization over the pupil become more symmetric but the intensity variation also becomes smaller overall.

Abstract: An x-ray system or method for exciting a sample under x-ray analysis, using a curved monochromating optic for directing a monochromatic x-ray beam from an x-ray source towards a first focal area. A second optic is positioned within, and receives, the monochromatic x-ray beam, and directs a focused x-ray beam towards a second focal area on the sample. A detector is positioned near the sample to collect radiation from the sample as a result of the focused x-ray beam. The curved monochromating optic produces a beam spot size at the first focal area larger than a beam spot size produced by the second optic at the second focal area, therefore, a beam spot size on the sample is thereby reduced using the second optic. Doubly-curved monochromating optics, and polycapillary optics, are disclosed as possible implementations of the optics.

Abstract: A zone plate multilayer structure includes a substrate carrying a plurality of alternating layers respectively formed of tungsten silicide (WSi2) and silicon (Si). The alternating layers are sequentially deposited precisely controlling a thickness of each layer from a minimum thickness of a first deposited layer adjacent the substrate to a maximum thickness of a last deposited layer. The first minimum thickness layer has a selected thickness of less than or equal to 5 nm with the thickness of the alternating layers monotonically increasing to provide a zone plate multilayer structure having a thickness of greater than 12 μm (microns). The x-rays are diffracted in Laue transmission geometry by the specific arrangement of silicon and tungsten silicide.

Abstract: An ultra-small angle X-ray scattering measuring apparatus includes a detector for detecting X-rays emitted from a sample, an X-ray collimating mirror arranged between the X-ray real focus and the sample, a monochromator arranged between the X-ray collimating mirror and the sample and an analyzer arranged between the sample and the detector. The X-ray collimating mirror includes a pair of X-ray mirrors that are arranged orthogonally relative to each other. The X-ray mirrors are multilayer film mirrors and their X-ray reflection surfaces are paraboloidal. The interplanar spacing of lattice planes of each of the multilayer films is continuously changed along the paraboloid so as to meet the Bragg's condition. The monochromator and the analyzer are formed by using a channel-cut crystal. The analyzer is driven to rotate for scanning around a 2θ-axial line and diffracted rays reduced to a spectrum by the analyzer are detected by the detector.
