Title: Self-alignment semiconductor device and manufacture thereof
Inventor: JIERII YUU
IPC: H01L21/331
Filed: 1989-12-22
Abstract: PURPOSE:To make it possible to manufacture a semiconductor device where a self-alignment contact is formed in a transistor element arranged inside a substrate by forming an opening of the transistor element in a mask layer which covers a substrate, and making it include a step to form a self-alignment contact using epitaxial lateral one-face growth. CONSTITUTION:A semiconductor substrate includes a collector region 12, to which a large amounts of impurities are implanted, and a sinker 14, which is adjacent to this. Both sides of this sinker 14 contact with dielectric insulating regions 20, and the substrate 10 is covered with a mask layer 18. This mask layer 18 is patterned for the range W, and an opening 22 is formed on an active base 16. An emitter contact 26 is formed in this region 22. Subsequently, the emitter contact 26 is heat-treated, and impurity concentration is made uniform over the whole emitter contact 26 and at the same time an emitter 24 is formed, and the emitter contact 26 self-aligns in the emitter region 24. When the emitter contact 26 grows and the emitter is formed, an inactive base region 32 is formed at the semiconductor substrate 10.

Title: Aluminum alloy substrate for magnetic disk and magnetic disk
Inventor: HAYASHI YUICHI
IPC: G11B5/73
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of the grinding of the plated layer of the surface of a substrate and to reduce the hours required for the grinding process by making a center line average roughness Ra of the surface to be within a specific range. SOLUTION: The surface of an aluminum alloy substrate is ground so that the surface roughness is made to be 100 to 200 Å in terms of the roughness Ra. If the roughness Ra is made not more 100 Å, nodules are increased after an Ni-P plating depending on the purity of the substrate or steps are generated on the surface of the substrate and the steps remain after the plating. On the other hand, if the roughness Ra exceeds 200 Å, substrate processing marks such as grinding process marks remain on the surface of the substrate even after a plating layer covering. By making the roughness Ra to be 100 to 200 Å, no intragrain step is generated, the substrate processing marks are covered by the plating layer and are made smooth. Thus, the amount of the grinding required after a plating is reduced.

Title: Fluid pulsation damping device
Inventor: SHIMOKAWA YOICHIRO
IPC: F15D1/02
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To stably feed stock solution by providing a projected part in which small holes for flow passages of the fluid are cut at the central part of a shielding plate fixed to a central inner circumferential wall of a cylindrical body to damp and absorb the pulsation of the stock solution. SOLUTION: When stock solution is fed to, e.g. a module filter 1 using a tube type pump, the solution is filled in a pulsation damping device 2 with intermittent pulsation. However, the rise of the solution level is stopped at the prescribed level due to the internal pressure of the air present in the pulsation damping device 2. After that, the solution rises through small holes 14 to reach an upper part of a shielding plate 11, and the solution is fed to the module filter 1. An air removing valve is operated to remove the air while the internal pressure is detected by a pressure gage. As a result, the solution which is fed with intermittent pulsation is stably fed to the module filter 1 because the pulsation is damped and absorbed by the pulsation damping device 2. The pulsation damping device 2, a cap 3, and a stock solution pipe 4 are directly cleaned.
