A method for producing a narrow pore comprises a step of radiating a particle beam onto a workpiece, and a step of carrying out anodic oxidation of the workpiece having been irradiated with the particle beam, to form a narrow pore in the workpiece.
摘要:
A method of manufacturing a nano structure by etching, using a substrate containing Si. A focused Ga ion or In ion beam is irradiated on the surface of the substrate containing Si. The Ga ions or the In ions are injected while sputtering away the surface of the substrate so that a layer containing Ga or In is formed on the surface of the substrate. Dry etching by a gas containing fluorine (F) is performed with the layer containing the Ga or the In formed on the surface of the substrate taken as an etching mask, and the nano structure is formed having a pattern of at least 2 μm tin in depth according to a predetermined line width.

An adhesiveness evaluation method can accurately evaluate the adhesiveness of a selected specific micro-spot of a specimen 1 of a small size. A part to be measured 5 is produced by isolating it from a surrounding part 4 and a μ-probe 6, which is a support member, is fixed to the part to be measured 5. Then, pulling force is applied to the part to be measured 5 by means of the μ-probe 6, which is the support member and fixed to it, to evaluate the adhesiveness of the part to be measured 5.
摘要:
A specimen holder including a specimen-holding table including a plane for placing a specimen, and a pair of members protruding from the plane, with the specimen-holding table being disposed between the pair of members. Here, the plane of the specimen-holding table is formed at an angle from a plane including top portions of the pair of members protruding from the plane of the specimen-holding table. The invention provides an electron microscope holder and a spacer used therein, which provide a high X-ray detection efficiency even when EDX analysis using an X-ray analyzer whose center axis only makes a small angle with a specimen-holding surface is performed on a specimen to be sectionally observed by TEM produced by FIB processing.
