  • Patent number: 8779400
    Abstract: An ion beam machining and observation method relevant to a technique of cross sectional observation of an electronic component, through which a sample is machined by using an ion beam and a charged particle beam processor capable of reducing the time it takes to fill up a processed hole with a high degree of flatness at the filled area. The observation device is capable of switching the kind of gas ion beam used for machining a sample with the kind of a gas ion beam used for observing the sample. To implement the switch between the kind of a gas ion beam used for sample machining and the kind of a gas ion beam used for sample observation, at least two gas introduction systems are used, each system having a gas cylinder, a gas tube, a gas volume control valve, and a stop valve.

  • Patent number: 8431891
    Abstract: An ion beam processing apparatus includes an ion beam irradiation optical system that irradiate a rectangular ion beam to a sample held on a first sample stage, an electron beam irradiation optical system that irradiates an electron beam to the sample, and a second sample stage on which a test piece, extracted from the sample by a probe, is mounted. An angle of irradiation of the ion beam can be tilted by rotating the second sample stage about a tilting axis. A controller controls the width of skew of an intensity profile representing an edge of the rectangular ion beam in a direction perpendicular to a first direction in which the tilting axis of the second sample stage is projected on the second sample stage surface so that the width will be smaller than the width of skew of an intensity profile representing another edge of the ion beam in a direction parallel to the first direction.

  • Patent number: 7810970
    Abstract: In the vehicle lighting control apparatus and method, it is determined that the user's steering wheel is returned from a steering angle existing in a saturated steering angle region toward a neutral steering angle region at a given speed or more. If such a steering condition is found, a swivel angle is calculated based on a swivel-angle control characteristic showing a monotonic decrease in the swivel angle when the steering angle decreases from the steering angle existing in the saturated steering angle range to a third preset angle. The third preset angle is an angle from which the swivel angle decreasing from the steering angle existing in the saturated steering range becomes zero. This calculated swivel angle is used to control the swivel angle of light irradiated from on-vehicle headlights.

  • Patent number: 7792621
    Abstract: An apparatus controls a swivel angle of on-vehicle headlights, the swivel angle of the lights being changeable in a lateral direction of the vehicle. A target swivel angle of the headlights is determined based on, for example, load map data of the road ahead the vehicle, and a control start point is determined based on the current position information and the road map data. The swivel angle is controlled to the target swivel angle in response to a state where the current position of the vehicle has reached the control start point. Running road shape-related information and a curvature direction of the road ahead are acquired. A control of the swivel angle toward the target swivel angle is prohibited when a direction of the target swivel angle determined is inconsistent with the curvature direction of the road, even in a case where the vehicle has reached the control start point.

  • Patent number: 7777183
    Abstract: A charged particle beam system, a sample processing method, and a semiconductor inspection system enable an accurate detection of a particle in a film without causing LMIS contamination and allow observation with an electron microscope quickly. A particle 65 causing a defect in a film 66 that has been detected with a separate optical inspection system is detected with an optical microscope 43 based on position information acquired by the separate optical inspection system. A sample 31 is processed with a nonmetal ion beam 22 so as to allow observation of the particle 65 with an electron microscope image or an ion microscope image, or ultimate analysis of the particle 65 with an EDX.

  • Patent number: 7700931
    Abstract: The present invention provides an ion beam processing technology for improving the precision in processing a section of a sample using an ion beam without making a processing time longer than a conventionally required processing time, and for shortening the time required for separating a micro test piece without breaking the sample or the time required for making preparations for the separation. An ion beam processing apparatus is structured so that an axis along which an ion beam is drawn out of an ion source and an ion beam irradiation axis along which the ion beam is irradiated to a sample mounted on a first sample stage will meet at an angle. Furthermore, the ion beam processing apparatus has a tilting ability to vary an angle of irradiation, at which the ion beam is irradiated to the sample, by rotating a second sample stage, on which a test piece extracted from the sample by performing ion beam processing is mounted, about the tilting axis of the second sample stage.

  • Patent number: 7696496
    Abstract: The apparatus for ion beam fabrication, which has been able to detect any anomalous condition of ion beams only by means of the current irradiated on the specimen, could not compensate the failure by investigating the cause and could not realize stable processing. To solve the problem described above, the present invention includes the first and second blankers and Faraday cups switches ON and OFF the first and second blankers and monitors beam current at two positions above and below the projection mask. By adopting this configuration, it will be possible to acquire the information on failure in ion beam, sort out the cause of the failure and to compensate the failure while limiting damages to the projection mask. As a result, it will be possible to realize stable processing by means of ion beam, and to use the ion beam fabricating device on a stable basis.
