Abstract: An X-ray diagnostic apparatus of an embodiment includes an image generator, a detection unit, and an irradiation control unit. The image generator successively generates X-ray images based on X-rays emitted from an X-ray tube and transmitted through a subject. The detection unit detects a position of a predetermined target included in the successively generated X-ray images. The irradiation control unit identifies, based on the detected position of the predetermined target, a region in which the predetermined target can be visualized in the X-ray images, and performs control to reduce an X-ray irradiation dose to a region other than the identified region.

Abstract: A pattern is applied to a substrate by a lithographic apparatus as part of a lithographic manufacturing system. Structures are produced with feature sizes less than 10 nm. A target includes one or more gratings with a direction of periodicity. A detector captures one or more diffraction spectra, to implement small angle X-ray scattering metrology. One or more properties, such as linewidth (CD), are calculated from the captured spectra for example by reconstruction. The irradiation direction defines a non-zero polar angle relative to a direction normal to the substrate and defines a non-zero azimuthal angle relative to the direction of periodicity, when projected onto a plane of the substrate. By selecting a suitable azimuthal angle, the diffraction efficiency of the target can be enhanced by a large factor. This allows measurement time to be reduced significantly compared with known techniques.

Abstract: In an X-ray radiation source, a counter wall made of alkali-containing glass, out of walls of a housing of an X-ray tube, is sandwiched between a filament and an electric field control electrode to each of which a negative high voltage is applied. This configuration prevents an electric field from being generated in the counter wall and thus suppresses precipitation of alkali ions from the glass. Therefore, it prevents change in potential relationship between electrodes at different potentials such as the filament, grid, and target and enables stable operation to be maintained, without occurrence of a trouble of failure in maintaining a desired X-ray amount.

Abstract: In an envelope rotation type X-ray tube apparatus, a cathode releases electrons, and the electrons released from the cathode are deflected by deflection coils. A target generates X-rays by being bombarded with the electrons deflected by the deflection coils. Here, a shield ring, while allowing passage through a ring interior of those of the electrons deflected by the deflection coils that head for an area of the target set beforehand, blocks electrons heading outward of the area. Consequently, the electrons are inhibited from bombarding on areas of the target outward of the area and an envelope. This can prevent damage to the envelope.
