摘要:
A cross-section processing and observation method includes: forming a first cross section in a sample by etching processing using a focused ion beam; obtaining image information of the first cross section by irradiating the focused ion beam to the first cross section; forming a second cross section by performing etching processing on the first cross section; obtaining image information of the second cross section by irradiating the focused ion beam to an irradiation region including the second cross section; displaying image information of a part of a display region of the irradiation region from the image information of the second cross section; displaying the image information of the first cross section by superimposing it on the image information being displayed; and moving the display region within the irradiation region. Observation images in which display regions are aligned can be obtained while reducing damage to the sample.

A cross-section processing and observation method includes: forming a cross section in a sample by a focused ion beam through etching processing; obtaining a cross-section observation image through cross-section observation by the focused ion beam; and forming a new cross section by performing etching processing in a region including the cross section and obtaining a cross-section observation image of the new cross section. A surface observation image of a region including a mark on the sample and the cross section is obtained. A position of the mark is recognized in the surface observation image and etching processing is performed on the cross section by setting, in reference to the position of the mark, a focused ion beam irradiation region in which to form the new cross section. Cross-section processing and observation is thus enabled continuously and efficiently using a focused ion beam apparatus having no SEM apparatus.

摘要:
A sample preparing device has a sample stage that supports a sample and undergoes rotation about a first rotation axis to bring a preselected direction of the sample piece into coincidence with an intersection line between a first plane formed by a surface of the sample piece and a second plane. A manipulator holds sample piece of the sample and undergoes rotation about a second rotation axis independently of the sample stage to rotate the sample piece to a preselected position in the state in which the preselected direction of the sample piece coincides with the intersection line. The manipulator is disposed relative to the sample stage so that an angle between the second rotation axis and the surface of the sample is in the range of 0° to 45°. The second plane corresponds to a plane obtained by rotating around the second rotation axis a line segment which is vertical to the surface of the sample and of which one end corresponds to an intersection between the surface of the sample and the second rotation axis.

摘要:
There are provided a detecting step of detecting secondary charged particles generated from an observation area of a sample when an electron beam or a focused ion beam is emitted onto the observation area under a certain irradiation condition; an image forming step of forming a plurality of observation images acquired by dividing the observation area and having an equal periodic pattern, from the secondary charged particles detected in the detecting step; and a defect recognizing step of recognizing a defect in the observation area from information on a difference acquired by comparing the plurality of observation images formed in the image forming step. Additionally, the detecting step, the image forming step, and the defect recognizing step are performed even when the electron beam or the focused ion beam is emitted onto the observation area under an irradiation condition different from the certain irradiation condition.
