When using a charged particle beam diaphragm having an annular shape in a charged particle beam device, arranging the charged particle beam diaphragm in the optimal loading position is difficult because the charged particle beam positioned directly on an optical axis having the highest current density within the charged particle beam is shielded. Consequently, the present invention is provided with a charged particle beam diaphragm 119 having a circular hole shape separately from a charged particle beam diaphragm 120 having an annular shape, and it is possible to switch between a situation in which the charged particle beam diaphragm having an annular shape is arranged on the optical axis of the charged particle beam and a situation in which the charged particle beam diaphragm having the circular hole shape is arranged on the optical axis of the charged beam particle.
The invention addresses the problem that, although a spherical surface aberration correction device wherein a circular hole electrode and a ring electrode have been combined is known as a device for correcting a positive spherical aberration of an electromagnetic lens for use in a charged-particle beam, when a voltage is applied between the circular hole electrode and the ring electrode in such a spherical surface aberration correction device, the focus of the charged-particle beam device varies due to a convex lens effect arising at the circular hole electrode. Therefore, in the charged-particle beam device of the present invention, comprising a charged-particle beam source (101) generating the charged-particle beam, a ring-shaped charged-particle beam aperture (120), and a charged-particle beam aperture power source (108) applying a voltage to the charged-particle beam aperture, the charged-particle beam aperture power source is constituted in such a manner as to apply to the charged-particle beam aperture a voltage yielding a polarity that is opposite to the charge of the charged-particle beam.

Abrégé
Disclosed is a heat dissipation structure, which has high thermal conductivity, has low thermal contact resistance by virtue of excellent contact with the surface of a counter material, and can absorb a thermal stress generated between the heat dissipation structure and the counter material. The heat dissipation structure is produced by heating a substrate, in which a part or the whole of the substrate surface is formed of SiC, in vacuo to sublimate silicon and to form a layer of carbon nanotubes on the substrate surface. In particular, the layer of CNT is preferably a layer of a plurality of CNTs grown substantially perpendicularly to the substrate surface. The heat dissipation structure having CNTs on the outermost surface thereof has low thermal contact resistance with the counter material because fine front ends of CNTs come into contact with even fine concaves and convexes on the surface of the counter material without providing any space.

A channel layer (40) for forming a part of the carrier path between a source electrode (100) and a drain electrode (110) is formed on a drift layer (30). The channel layer (40) is composed of Ge granular crystals formed on the drift layer (30), and a cap layer covering the Ge granular crystals.
An upper side half (1) of a resin-shaping mold which bears both a cavity member (6) constituting the inner bottom face (5) of a cavity (4) and a surround member (7). The cavity member (6) is a low-adhesion material according to the present invention which is composed of a body (8) and a face (10) formed on the underside (9) of the body (8) that is to come into contact with a fluid resin. The body (8) is made of a material consisting of the first material 3YSZ and the second material ZrN at a prescribed ratio. The face (10) is made of Y2O3 exhibiting low adhesion to cured resins and has a lower thermal expansion coefficient than that of the body (8). The cavity member (6) is produced by joining the body (8) and the face (10) at high temperature and then cooling the obtained composite, whereby a compressive residual stress is generated in the face (10) owing to the difference in thermal expansion coefficient and remains in the face (10).
The surface (6) of a mold (1) for molding resins is made of a low-adhesion material (3) consisting of a solid solution, La-Y2O3, made from Y2O3 and another oxide, La2O3. La2O3 contains La having an ionic radius larger than that of Y3+ and therefore exhibits basicity stronger than that of Y2O3, while the low-adhesion material (3) has a prescribed La2O3 content based on the total amount of Y2O3 and La2O3. By virtue of these characteristics, the low-adhesion material (3) is reduced in the number of sites per unit area as compared with that of Y2O3 owing to the ionic radius and weakened in the binding strength for a basic substance owing to the basicity and maintains shape retentivity owing to the content. Thus, the surface (6) is made of a low-adhesion material (3) having lower adhesion than that of Y2O3 and excellent shape retentivity. The invention provides a low-adhesion material which has lower adhesion for a basic substance than that of Y2O3 and excellent shape retentivity and molds for molding resins which have excellent mold release properties and shape retentivity.

A technology for reducing the influence of a wave acting on an observation object when observation is carried out by causing a wave to act on the observation object. A plurality of waves having coherence are generated and the intensity of a wave acting on the observation object (SPC) is reduced to one half or less of the average intensity of waves at the position of the observation object by causing interference of the plurality of waves. At least one of the plurality of waves interacted with the observation object (SPC) is observed.
