Patent JP-H07283380-A (JP)
Title: Semiconductor substrate and its manufacture
Inventor: INOUE SHUNSUKE
IPC: H01L27/12
Filed: 1994-04-08
Abstract: PURPOSE:To obtain, at low costs, a semiconductor substrate in which a crystal defect is small, in which the distribution of a film thickness is good, in which an impurity concentration is low and in which the film thickness and the material of an insulating layer are set freely by a method wherein a semiconductor layer whose impurity concentration has been lowered by an external diffusion operation is provided on an insulator face. CONSTITUTION:A semiconductor substrate 104 which has a heavily doped layer 101b on the surface side is pasted on a substrate 103 which has an insulator face 102. After that, the semiconductor substrate 104 is removed, and a heavily doped layer 101b on the insulator face 102 is formed. Then, the impurity concentration of the heavily doped layer 101b is lowered by an external diffusion operation by means of a heat treatment. When the layer 102 which is provided with the diffusion prevention capability of impurities exists just under a silicon layer 101a in this manner, it is possible to prevent the impurities from creeping into the SiO2 layer 102 in the external diffusion operation. As a result, the external diffusion operation is performed efficiently, and it is possible to obtain an SOI substrate which is provided with the Si layer 103 whose impurity concentration is lower.

Title: Production of magnetic recording medium
Inventor: YAMANO MINORU
IPC: G11B5/845
Filed: 1983-04-20
Abstract: PURPOSE:To obtain a magnetic recording medium suitable for high density recording by orienting perpendicularly the axis of easy magnetization of the magnetic particles in a coated film by a magnetic fluid so that the magnetic particles are satisfactorily perpendicularly oriented by a relatively small magnetic field. CONSTITUTION:In the figure, 51, 51 are opposed N-S magnets disposed in a drying machine 6 and the lower magnet 51 is embedded in a magnetic fluid 9 contained in a container 8. The fluid 9 is formed by dispersing pulverous particles of, for example, magnetite powder, in a colloid state into a solvent and if the magnet 51 is embeded into such fluid 9, the fluid 9 gathers at the place where the magnetic flux is dense and the part above the N pole of the magnet 51 builds up. A base 2 travels while contacting with such magnetic fluid 9. The distance between the magnet 51 and the coated film 4 on the base 3 approaches to the thickness of the base 2 and the diamagnetic field in the coated film decreases.

Title: X-ray diffraction method and x-ray diffraction device
Inventor: KOBAYASHI YUJI
IPC: G01N23/207
Filed: 1990-03-23
Abstract: PURPOSE:To provide the X-ray diffraction method which can make full utilization of a goniometer by moving a photodetecting slit and an X-ray detector in the direction orthogonal with the rotating direction of a detector support as the detector support rotates. CONSTITUTION:A sample 60 is mounted to a sample base and while an X-ray focus 10 and the sample 60 are held static, the sample 60 is irradiated with X-rays from the X-ray focus 10. The diffracted X-ray intensity is measured by the X-ray detector 30 while the detector support 20 is kept rotated. Since the x-ray focus 10 and the sample 60 are held static, a focus circle 1 does not change. A moving base 22 is so linearly moved on the detector support 20 that the photodetecting slit 40 comes on the focus circle 1 at all times as the detector support 20 rotates. Namely, the moving base 22 is imposed on the detector support 20 of the goniometer of an theta-2theta scanning system. A sample base driving mechanism and a detector support driving mechanism are disconnected so that the sample base maintains the static state even if the detector support 20 rotates. The X-ray diffraction method is executed by fully utilizing the theta-2theta scanning method in this way.
