Abstract:
There is provided a projection objective for a projection exposure apparatus that has a primary light source for emitting electromagnetic radiation having a chief ray with a wavelength≦193 nm. The projection objective includes an object plane, a first mirror, a second mirror, a third mirror, a fourth mirror; and an image plane. The object plane, the first mirror, the second mirror, the third mirror, the fourth mirror and the image plane are arranged in a centered arrangement around a common optical axis. The first mirror, the second mirror, the third mirror, and the fourth mirror are situated between the object plane and the image plane. The chief ray, when incident on an object situated in the object plane, in a direction from the primary light source, is inclined away from the common optical axis.

Abstract:
In an apparatus and a method for the analysis of atomic or molecular elements contained in a sample by wavelength dispersive X-ray spectrometry, wherein primary x ray or electron radiation is directed onto the sample whereby fluorescence radiation is emitted from the sample, the fluorescence radiation is directed onto a mirror or focussing device consisting of a multi-layer structure including pairs of layers of which one layer of a pair comprises carbon or scandium and the other comprises a metal oxide or a metal nitride and the fluorescence radiation is reflected from the mirror or focussing device onto an analysis detector for the analysis of the atomic or molecular elements contained in the sample.
Abstract:
A method is described for the production of thin boron and titanium/boron films by magnetron sputter deposition. The amorphous boron films contain no morphological growth features, unlike those found when thin films are prepared by various physical vapor deposition processes. Magnetron sputter deposition method requires the use of a high density crystalline boron sputter target which is prepared by hot isostatic pressing. Thin boron films prepared by this method are useful for producing hardened surfaces, surfacing machine tools, etc. and for ultra-thin band pass filters as well as the low Z element in low Z/high Z optical components, such as mirrors which enhance reflectivity from grazing to normal incidence.
Abstract:
The reflectivity of multilayered EUV mirrors tuned for 11-16 nm, for which the two-component Mo/Be and Mo/Si multilayered systems are commonly used, is enhanced by incorporating additional elements and their compounds mainly from period 5 of the periodic table. In addition, the reflectivity performance of the multilayer stacks is further enhanced by a numerical global optimization procedure by which the layer thicknesses are varied for optimum performance in, contradistinction to the constant layer thickness—i.e. constant partition ration—multilayer stacks commonly designed and fabricated hitherto. By incorporating additional materials with differing complex refractive indices in various regions of the stack, or by wholly replacing one of the components (typically Mo), peak reflectivity enhancements of up to 5% for a single reflector are achieved, compared to a standard unoptimized stack. The additional materials used are: Rb, RbCl, Sr, Y, Zr, Ru, Rh, Tc, Pd, Nb and Be. Protective capping layers of B, Ru, Rh, C, Si3N4, SiC, are disclosed.

Abstract:
This invention relates to novel methods of producing flat and curved optical elements with laterally and depth graded multilayer thin films, in particular multilayers of extremely high precision, for use with soft and hard x-rays and neutrons and the optical elements achieved by these methods. In order to improve the performance of an optical element, errors in d spacing and curvature are isolated and subsequently compensated.
Abstract:
X-ray wave diffraction devices are constructed using atomic layer epetaxy. A crystalline substrate is prepared with one or more surface areas on which multiple pairs of layers of material are to be deposited. These layers are then formed by atomic layer epetaxy on the surface areas of the substrate, one on top of another, with the material of each layer of each pair being selected to have a different index of refraction from that of the material of the other layer of each pair. The layers are formed so that the thickness of each layer of a pair is substantially the same as that of the corresponding layer of every other pair and so that x-ray waves impinging on the layers may be reflected therefrom. Layer pairs having a thickness of about 20 angstroms or less are formed on the substrate.
Abstract:
A mirror for SOR includes a base (1) made of a heat resistant ceramic material having a surface, a first SiC coating (2, 3) formed on the surface of the base (1), which has a first smoothed surface, and a second SiC coating (4, 5) formed on the first smoothed surface of the first SiC coating (2, 3), which has a second smoothed surface. A third SiC coating can be formed on the smoothed surface of the second SiC coating (4).
