Title: Forming method for metal film pattern
Inventor: NAKAGAWA YOSHIAKI
IPC: H01L43/12
Filed: 1989-03-22
Abstract: PURPOSE:To obtain a predetermined metal film pattern without coating with etching resist at the time of chemically etching by radiating the surface of the metal film in a predetermined pattern with ions to impart etching resistance against chemical etching, and then chemically etching it. CONSTITUTION:After a metal film 4 is formed on a support 1, the surface of the film 4 is radiated in a predetermined pattern with ions, etching resistance is imparted to chemical etching, and then chemically etched. For example, after a plated base film 2 is formed on the support 1, the film 4 by plating is formed. Then, the film 4 is covered with a resist mask 6 having a predetermined pattern, and only a metal film pattern 41 in the resist pattern is radiated with the ions. Subsequently, after the mask 6 is removed, it is chemically etched. Then, a selective etching in which a metal film 42 not radiated with the ions and the film 2 are removed and the pattern 41 radiated with the ions and the film remain without removing is executed.

Filed: 1986-03-28
Abstract: PURPOSE:To enable miniaturization and lightening, and to reduce fuel cost by mounting a clutch mechanism, in which a shaft is to some extert turned and a fan follows, between the shaft and the fan. CONSTITUTION:When a coil 17 is supplied with an AC power supply through a terminal 26, a rotor 20 is rotated and driven. When a shaft 19 and a disk 15 begin to be rotated, an indenter 12 constituting a clutch mechanism 40 and a rubber 21 for a boss 22 are separated, and a fan 10 does not follow the shaft 19 and is not revoled.

Abstract: PURPOSE:To prevent the generation of short circuit and leakage due to the end-surface-coat of a metal reflecting film, by forming a part extending from the end surface of one side of a light emitting surface of a laser element to a surface neighbouring with the above-mentioned surface. CONSTITUTION:A light emitting surface 12 of a semiconductor laser element 11 is arranged upwards on a jig 10, and the surface is sandwiched by spacers 15 made of silicon and the like which are longer than the cavity length of the element 11. An insulating film serving as a reflecting film, e.g., Al2O3 film 14 is vapor-deposited. At this time, not only the end surface but also the surface neighboring with the end surface are coated with the Al2O3 film. Only the end surface of the semiconductor laser element 11 sandwiched by the spacers 15 made of, e.g., silicon and the like which are longer than the cavity length of the element 11 is exposed. In this state, an Au film 16 is vapor-deposited to 500Angstrom  thickness. As the insulating film 14 neighbors with the end surface of the element 11 and reaches also the electrode sides, the short circuit and leakage of the electrode caused by the deposited film 16 can be prevented.
