PROBLEM TO BE SOLVED: To provide a sample holder and an ion beam processing device capable of preparing easily a favorable sample suitable for observation. SOLUTION: A sample setting part 9 has a sample bonding face 10. A shielding material guide part 12 is arranged on the sample setting part 9, and the shielding material guide part 12 is fixed in the sample setting part 9. The shielding material guide part 12 has a shielding material guide face 13. The sample bonding face 10 is positioned at a place lowered by D=40μm from the shielding material guide face 13. Since the sample bonding face 10 is formed in the position lowered by 40μm from the shielding material guide face 13 by this manner, the sample 7 is brought into a state projected frontwards by 60μm from the shielding material guide face 13 as shown in Fig.(d), when the sample 7 with 100μm of thickness is attached onto the sample bonding face 10. A shielding material 16 having about 20μm of thickness is set on the shielding material guide face 13. COPYRIGHT: (C)2006,JPO&NCIPI
摘要:
A method for preparing an iridium tip with atomic sharpness. The method includes tapering an iridium wire to a needle shape and heating the iridium needle in an oxygen atmosphere. Also disclosed is an iridium needle having a pyramidal structure which terminates with a small number of atoms prepared by the methods.

PROBLEM TO BE SOLVED: To process a workpiece in one processing with high accuracy.SOLUTION: A processing method includes: changing a relative orientation of a unit removal shape and the workpiece; positioning a relative position of a rotation shaft of a rotating polishing tool and the workpiece so as to have a relative orientation having a smallest difference among differences between a calculated removal shape and a target removal shape determined for each of the relative orientations; and processing the workpiece at a relative speed in accordance with a dwell time distribution. Accordingly, the processing method is capable of processing the workpiece with less error in one scanning for processing, thereby increasing the precision of a workpiece surface and improving the efficiency of processing by reducing the frequency of repetition of the processing.

PROBLEM TO BE SOLVED: To provide an improved method of controlling topographical variations when milling a cross-section of a structure, which can be used to reduce topographical variation on a cross-section of a write-head in order to improve measurement accuracy.SOLUTION: Topographical variation is reduced by a protective layer that comprises a material having mill rates at higher incidence angles that closely approximate the mill rates of a structure at those higher incidence angles. Topographical variation can be intentionally introduced by using a protective layer that comprises a material having mill rates at higher incidence angles that do not closely approximate the mill rates of the structure at those higher incidence angles.

PROBLEM TO BE SOLVED: To reduce processing time for shape correction processing and smoothing processing in processing of an optical element requiring high shape accuracy. SOLUTION: A workpiece surface 100 is processed by simultaneously irradiating a plurality of charged-particle beams to the workpiece surface 100 in the same relative movement. A first charged-particle beam of the plurality of the charged-particle beams performing the same relative movement is an ion beam 101 for shape correction processing which performs the shape correction processing by variably controlling scanning speed along a raster scanning locus 103. A second charged-particle beam is an ion beam 102 for smoothing processing which performs the smoothing processing by variably controlling a pulse width and a current amount corresponding to the change of the scanning speed. A plurality of processings in which the distribution of the number of unit attainment particles is different at the workpiece surface 100 are simultaneously carried out so that processing time is reduced.
