    Abstract: PROBLEM TO BE SOLVED: To provide a fine particle structure body for preventing aggregation, a light-emitting device using it, and a method for manufacturing the fine particle structure body. SOLUTION: A fine particle structure body is provided with a plurality of fine particles 11, made of ZnO or the like, and each of the fine particles 11 is connected to one another in a network form by a crosslinking part 12. More specifically, the crosslinking part 12 that exists among particles becomes a support part, thus preventing the fine particles 11 from being aggregated. Each of the fine particles 11 is composed of a fine crystal with a crystal particle diameter of 100 nm or less and has an inter-band luminous function and a donor acceptor pair luminous function. This sort of fine particle structure body is used as a material for composing the luminous part of a light-emitting device. The fine particle structure body is manufactured by applying a voltage between positive and negative electrodes with pure water as an electrolyte, a highly pure Zn plate as the positive electrode, and a semiconductor substrate as the negative electrode.

SOLUTION: A recording head HR is composed of a leaf spring in a narrowplate shape or the like formed with an acicular electrode 21 in a conical shape, a triangular pyramidal shape or prismatic shape having a cross section of a triangle, etc., at the tip, capable of point contact or microarea contact with the recording medium, and is constituted of a cantilever 22 whose one end is fixed. This cantilever 22 consists of Si of a spring constant 0.01 to 10N/m or SiN, and high electric conductivity is imparted to the cantilever by coating its surface with a metal layer or metal layers in a single layer or multilayer structure of Au, Pt, Co, Ni, Ir, Cr, etc. The recording medium 10 is placed on a placing base 30, and is moved, for instance, in the directions of x-axis y-axis, which are orthogonal to each other or is rotated, while the placing base 30 is controllable of moving in the direction of z-axis which is perpendicular to the surface direction of the recording medium 10, so as to adjust a state of contact with the acicular electrode 21.

    Abstract: PURPOSE:To suppress an aggregating phenomenon during recrystallization through good wettability between SiO2 film and a semiconductor thin film by forming an SiO2 film on the surface of the semiconductor thin film and conducting heat treatment in an oxygen atmosphere or a nitrogen atmosphere prior to recrystallization by energy irradiation. CONSTITUTION:A polycrystaline silicon thin film 22 is formed by the CVD method on a quartz substrate 21 and an SiO2 film 25 is then formed by the CVD method thereon. Next, an SiO2 film 26 is formed by the plasma CVD method on the CVD SiO2 film 25 to prepare a sample 27. This sample 7 is then annealed at 1000 deg.C for 200 minutes in an oxygen atmosphere and the polycrystal silicon thin film 22 is melted for recrystallization by the zone melting method using a graphite strip heater. According to this method, in the zone melt recrystallization in an SiO2 film/Si thin film/SiO2 film (thermal oxidation) or a quartz substrate structure, the aggregation phenomenon of silicon film can be suppressed, and as a result a so-called SOI substrate of high quality can be prepared.

    Abstract: PURPOSE:To detect the fused state of a semiconductor layer by a method wherein, when the semiconductor layer is fused by projecting an energy beam, the radiant light to be emitted from the semiconductor layer is imaged. CONSTITUTION:The incident angles of two beams of an energy beam (melting beam) 21 and a preheating beam 22 are respectively changed and the two beams 21 and 22 are made to incide in a lens 6 and are projected on a sample 1. As the polycrystalline silicon film, which is made its temperature rise, emits radiant light, the radiant light is enlarged by a microscope 4, is imaged by a TV camera, which is the imaging means, and is displayed on a monitoring TV 5. At this time, as laser beam having a powerful intensity also incides in the imaging means 3 (TV camera) through the microscope 4, an Ar laser beam cutting filter 32 is set in before the imaging means 3 so that the radiant light only comes into the TV camera 3. Moreover, for viewing simultaneously the pattern configuration and the part heated with the beam 22, a high-speed shutter 31, which synchronizes with the imaging means 3, is set in before the microscope 4. By this constitution, the radiant light to be emitted from the part heated with the laser beam 22 is intensified along with the temperature of the heated part, but once the part fuses, the intensity of the radiant light drops and the boundary between the solid phase part and the liquid phase part is distinctly identified.

    Abstract: PURPOSE:To obtain the title thin film having the (100) plane direction and excellent flatness and to prevent the generation of cracks therein by a method wherein, after a film layer is formed on the polycrystalline semiconductor film in which specific impurities are introduced, the polycrystalline semiconductor film is fused by heating, and a recrystallizing process is performed. CONSTITUTION:The oxygen (O) atoms, which are introduced while a film is being grown, of 5X10 cm are distributed in the average density of the entire film on the crystal grain boundary 2b between the crystal grains 2a located in the polycrystalline Si film 2 formed on a quartz substrate 1. Then, an SiO2 film 3 of 3000Angstrom or thereabout in thickness, which constitutes a cap layer, is formed on the polycrystalline Si film by performing a CVD method. Subsequently, the polycrystalline Si film 2 is fused and recrystallized by scanningly projecting a laser beam 4 emitted from an Ar laser on the substrate. As a result, a single crystal Si film 5 is formed. The single crystal Si film 5 formed as above-mentioned has the (100) plane direction. Also, as a recrystallising process is performed under the condition wherein the SiO2 film 3 is formed as a cap layer, the obtained single crystal Si film 5 has a flat surface, and almost no cracks are generated thereon.

    Abstract: PROBLEM TO BE SOLVED: To measure a strain in a crystal at high positional resolution. SOLUTION: A positional change in intensity of a diffracted X-ray from the sample crystal 6 is detected via an X-ray image magnifying crystal 10 fixed within a diffraction angle range, using an optical system of an X-ray topograhpy arranged with the X-ray image magnifying crystal 10 in a rear stage of the sample crystal 6 of which the strain is measured. The positional change of the diffracted X-ray intensity found based on a X-ray topograph provided by the X-ray image magnifying crystal 10 is converted into a shift of a Bragg angle in the sample crystal 6.

    Abstract: PURPOSE:To accurately and easily measure distortion in a crystal and with a high position resolution. CONSTITUTION:The diffraction X-ray intensity curve of a sample crystal 6 is measured by using the optical system of an X-ray topography, the part of the low-angle side is approximated by an exponential function, and then the original diffraction X-ray intensity curve is plotted again by using the logarithmic function which is the inverse function of the function, thus enabling the relationship between the X-ray incidence angle and the change in the diffraction X-ray intensity to be linear. Then, the change rate of the change in the diffraction X-ray intensity which is linear to the X-ray incidence angle is obtained from the inclination of the plotted curve and then two constituents (DELTAd/d, DELTAalpha) of distortion in a sample crystal 6 are obtained by calculated using the change rate. An X-ray topography optical system where a crystal for enlarging an X-ray image is laid out at the later stage of the sample crystal 6 is used to enhance the position resolution for measuring distortion.
