Abstract:
A grazing incidence reflector (300) for EUV radiation includes a first mirror layer (310) and a multilayer mirror structure (320) beneath the first mirror layer. The first mirror layer reflects at least partially EUV radiation incident on the reflector with grazing incidence angles in a first range, and the first mirror layer transmits EUV radiation in a second range of incidence angles, which overlaps and extends beyond the first range of incidence angles. The multilayer mirror structure reflects EUV radiation that is incident on the reflector with grazing incidence angles in a second range that penetrates through the first mirror layer. A grazing incidence reflector can be used in a lithographic apparatus and in manufacturing a device by a lithographic process.

Abstract:
A X-ray waveguide includes a core (101) for guiding X-rays having a wavelength band in which the real part of refractive index of material is smaller than 1 and a cladding (102, 103) for confining the X-rays in the core. The core has a one - dimensional periodic structure in which a plurality of layers respectively formed of inorganic materials having different real parts of refractive index are periodically laminated. The core and the cladding are configured so that a critical angle for total reflection for the X-rays at an interface between the core and the cladding is larger than a Bragg angle due to a periodicity of the one - dimensional periodic structure. A critical angle for total reflection for the X-rays at an interface between layers in the one - dimensional periodic structure is smaller than the Bragg angle due to the periodicity of the one - dimensional periodic structure.

Further, the body comprises a coating on or on almost its entire surface, wherein the coating reflects IR radiation inside the body.
Abstract:
A lithographic apparatus includes a radiation source configured to produce a radiation beam, and a support configured to support a patterning device. The patterning device is configured to impart the radiation beam with a pattern to form a patterned radiation beam. A chamber is located between the radiation source and patterning device. The chamber contains at least one optical component configured to reflect the radiation beam, and is configured to permit radiation from the radiation source to pass therethrough. A membrane (44) is configured to permit the passage of the radiation beam, and to prevent the passage of contamination particles (54) through the membrane. A particle trapping structure (52) is configured to permit gas to flow along an indirect path from inside the chamber to outside the chamber. The indirect path is configured to substantially prevent the passage of contamination particles (58) from inside the chamber to outside the chamber.

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.
Abstract:
A multi-energy imaging system and method for selectively generating high-energy X-rays and low-energy X-ray beams are described. A pair of optic devices are used, one optic device being formed to emit high X-ray energies and the other optic device being formed to emit low X-ray energies. A selective filtering mechanism is used to filter the high X-ray energies from the low X-ray energies. The optic devices have at least a first solid phase layer having a first index of refraction with a first photon transmission property and a second solid phase layer having a second index of refraction with a second photon transmission property. The first and second layers are conformal to each other.

The chamber (3) includes a radiation source (50) configured to generate radiation (B), and a radiation collector (70) configured to collect radiation (B) generated by the source (50), to transmit collected radiation to a radiation beam emission aperture (60). A spectral purity filter (80) enhances a spectral purity of the radiation (B) that is to be emitted via the aperture (60). The filter (80) is divided the chamber (3) into a high pressure region (Rl) and a low pressure region (R2).
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.
