  • Publication number: 20150014526
    Abstract: The present invention provides a multi-view X-ray inspection system. In one embodiment, a beam steering mechanism directs the electron beam from an X-ray source to multiple production targets which generate X-rays for scanning which are subsequently detected by a plurality of detectors to produce multiple image slices (views). The system is adapted for use in CT systems. In one embodiment of a CT system, an electron beam generated by a single radiation source is steered by an electron beam transport mechanism comprising at least two dipoles and a quadrupole on to a target arranged in an approximated arc. The inspection system, in any configuration, can be deployed inside a vehicle for use as a mobile detection system.

  • Patent number: 8921781
    Abstract: In the case of inspecting samples having different sizes by means of a semiconductor inspecting apparatus, a primary electron beam bends since distribution is disturbed on an equipotential surface at the vicinity of the sample at the time of inspecting vicinities of the sample, and what is called a positional shift is generated. A potential correcting electrode is arranged outside the sample and at a position lower than the sample lower surface, and a potential lower than that of the sample is applied. Furthermore, a voltage to be applied to the potential correcting electrode is controlled corresponding to a distance between the inspecting position and a sample outer end, sample thickness and irradiation conditions of the primary electron beam.

    Abstract: A sample holder for an electron microscope has multiple sample stands, can allow at least one sample stand to move, and enables multiple samples for a transmission electron microscope to be prepared by a focused ion beam apparatus. A holder tip opening is provided in a tip of the sample holder. A back end of the sample holder has a knob, a rolling mechanism, a coarse adjustment mechanism, and a connector. By pressing the knob, fixation of the rolling mechanism is canceled, and the back end from the rolling mechanism and the tip of the sample holder will rotate. This rolling mechanism enables arrangement of the samples to be rotated in both the observing of a sample and the preparing of a sample for a transmission electron microscope with the focused ion beam apparatus. Moreover, the sample stand is movable by the coarse adjustment mechanism and the fine adjustment mechanism.
