摘要： 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.

摘要： 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.

摘要： Provided is a technique for accurately taking out a defect detected by an electron beam, and for analyzing the defect. In this technique, a defective portion in a wafer is detected by the irradiation of the electron beam. A mark made of a deposition layer is formed by irradiating the electron beam onto the defective portion while supplying a deposition gas thereto. On the basis of this mark, the defective portion is machined into a sample piece by using a projection ion beam generated from a gas ion source, and thereby the defective portion is taken out.

摘要： 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. The ion beam processing apparatus is structured so that a segment drawn by projecting the axis, along which the ion beam is drawn out of the ion source, on a plane perpendicular to the ion beam irradiation axis can be at least substantially parallel to a segment drawn by projecting the tilting axis of the second sample stage on the plane perpendicular to the ion beam irradiation axis.
