The method further includes the step of calculate a mean value of the merit functions o f the first plurality of structures or mutations present in each first or second domain and define a threshold value to said mean value; then, for each first plurality of structures or mutations present in each first or second domain whose merit function is enhanced of the threshold with respect to the mean value, subst itute a third domain to the first or second domain unt il the corresponding merit function is enhanced of said predetermined threshold. Then, the preceding step are repeated unt il the time interval has lapsed and the merit funct ions of the first plurality of structures or mutations present in each first domain are compared and the structure or mutation whose merit function is the more enhanced is selected.

    Abstract: Systems and methods are disclosed for cleaning a chamber window of an extreme ultraviolet (EUV) light source. The window may have an inside surface facing a chamber interior and an opposed outside surface and the light source may generate debris by plasma formation. For the system, a subsystem may be positioned outside the chamber and may be operable to pass energy through the window to heat debris accumulating on the inside surface of the window. In a first embodiment, the subsystem may place a flowing, heated gas in contact with the outside surface of the window. In another embodiment, electromagnetic radiation may be passed through the window.

    Abstract: Die Erfindung betrifft Masken mit einer Multilayerbeschichtung einer bestimmten Periodendickenverteilung, wie sie in Lithographievorrichtungen zur Herstellung von Halbleiterbauelementen verwendet werden. Ein Problem von Projektionsoptiken ist die Pupillenapodisierung, die zu Abbildungsfehlern führt. Erfindungsgemässe wird vorgeschlagen, die Periodendicke in der Maskenebene grösser als die für maximale Reflektivät ideale Periodendicke zu wählen. Dadurch wird nicht nur die Apodisierung über die Pupille symmetrischer, sondern auch die Intensitätsvariation wird insgesamt geringer.

    Abstract: The light of a broad energy band can be observed by reflecting the light of the broad energy band, for example, the light from the visible light region to the X-ray region at a high reflectance, respectively, by a composite telescope including a normal incidence optical system and an oblique incidence optical system. A broadband telescope comprises an oblique incidence optical system unit in which the light is obliquely incident on a surface part for reflecting the incident light, a normal incidence optical system unit in which the light is substantially vertically incident on a surface part for reflecting the incident light, and an analyzer for spectrum analysis of the light reflected by the surface part of the obliquely incidence optical system unit and the light reflected by the surface part of the normal incidence optical system unit.

    Abstract: A method of manufacturing an X-ray optical element. The element consists of a body of a material having a shape memory. At a high temperature, i.e. a temperature beyond the transition temperature of the material, the body is pressed so as to impart a first, desired shape. A surface of the body is thus shaped for example, as a logarithmic spiral or as another curved shape. After cooling to a low temperature, i.e. a temperature below the transition temperature of the material, a second, machinable shape is imparted to the body, preferably a flat surface. A number of precision operations can be performed on this second, machinable shape, for example polishing to a surface roughness of 0.5 nm RMS. Subsequent to this precision operation, the body is heated and resumes its first, desired shape which is retained after cooling. The body can be provided, if desired, with a comparatively thin surface layer which is also polished in the flat shape and which bends when the body resumes the desired shape. This layer can be chosen on the basis of desired mechanical (polishability) or X-ray optical properties. The X-ray optical element may comprise notably a multilayer mirror for X-ray purposes, thus forming a high-precision crystal for wavelength analysis.
