Patent JP-S63166269-A (JP)
Title: Complementary lateral insulated gate rectifier
Inventor: EDOWAADO HENRII SUTATSUPU
IPC: H01L27/08
Filed: 1987-12-22
Abstract: A complementary Lateral Insulated Gate Rectifier (LIGR) includes two complementary LIGR structures fabricated in adjacent surface-adjoining semiconductor wells of the same conductivity type in a semiconductor substrate. The two LIGR structures are of generally similar configuration, thus simplifying the manufacturing process, and the proposed design additionally permits the n-channel and p-channel LIGR structures to have comparable "on" resitances. The two LIGR structures, otherwise isolated by a portion of the substrate separating the two semiconductor wells, are connected together by a common source electrode. The resulting complementary Lateral Insulated Gate Rectifier features a compact, integrated structure in which the "on" resistances of both the n-channel and p-channel portions of the device are comparable.

Abstract: PURPOSE:To eliminate the irregularity in hole width by a method wherein the longitudinal width of the hole for diffusion is determined by the side wall, and the lateral width is determined by the insulating film to be etched. CONSTITUTION:A polysilicon film is formed using a pressure-reduced vapor growth method, and a polysilicon side wail 109 is formed by conducting anisotropic etching. As a result, the lateral width dimensions of an emitter aperture is determined, using the lithography pattern which was used before, a photoresist 113, which is orthogonally intersecting with the former pattern, is formed and also an etching pattern 114 is formed. The surface of a single crystal silicon substrate 101 is exposed by etching a silicon oxide film 106, a diffusion hole 110 is formed, and longitudinal width dimensions are determined. As a result, the four corners 112 of the diffusion hole 110 are formed in almost at right angles, the irregularity of the area of the emitter region is reduced, and the irregularity in electric characteristics of the device can also be reduced.

Title: Magnetic recording medium
Inventor: SASAKI KENJI
IPC: G11B5/842
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To improve the orientation of the longitudinal direction of the ferromagnetic powder of a thin type magnetic layer and to enable the improvement in a high-frequency range output characteristic and the reduction of an error rate by specifying a magnetic layer thickness to a specific value or below and the ratio of the respective squareness ratios in perpendicular and longitudinal directions to specific values or below. SOLUTION: The thickness of the magnetic layer 4 of the magnetic recording medium 1 is specified <=0.5 μm and the ratio Sq⊥/sq|| of the squareness ratios Sq⊥, sq|| of the perpendicular and longitudinal directions thereof is specified to <=0.4 m. As a result, the alignment to the longitudinal direction of the ferromagnetic powder is improved and the magnetization inversion of the once magnetized ferromagnetic powder does not occur. In addition, the magnetization inversion sharpens. Consequently, sharpened reproduction waveforms, decreased interference between waveforms and a lowered error rate are resulted. The ratio Sq⊥/sq|| nearer zero is more preferable.  The squareness ratios Sq⊥, sq|| are defined by the ratio of the residual magnetic flux densities and the saturation magnetic flux densities in the perpendicular and longitudinal directions.
