Patent JP-S61183942-A (JP)
Title: Manufacture of semiconductor device
Inventor: FUJITA ICHIRO
IPC: H01L21/768
Filed: 1985-02-08
Abstract: PURPOSE:To obtain the junction layer of stability and reproducibility by a method wherein a metallic layer and a Ti nitride layer are successively formed over an Si substrate with an insulation layer having contact windows and are heated to form a metallic silicide layer; then, a layer containing aluminum is formed over the Ti nitride layer. CONSTITUTION:When a substrate with a double-layer film of a Ti layer 8 and a Ti nitride (TiN) layer 9 formed in contact with a contact window 5 is heat-treated at about 600 deg.C for approx. 10min, the Ti layer 8 reacts with the Si constituting a semiconductor region 4 in the contact window 5, resulting in the formation of a TiSi2 layer 10. In this case, because of being thermally stable, the TiN layer 9 acts as a protection wall against oxidation, and the Ti layer 8 is not oxidized. Next, the TiN layer 9 contaminated and partly oxidized by heat treatment is ridded of the surface layer by sputter etching; then, a resist is patterned by Al evaporation and dry-etched with a gas such as carbon tetrachloride, thus obtaining an Al wiring pattern 11. The TiN layer 9 is heated through a multilayer treatment successively performed thereafter and is reduced in resistance by the advancement of Al diffusion.

Inventor: YOSHIDA NORIYUKI
IPC: G02B6/36
Filed: 1987-02-03
Abstract: PURPOSE:To prevent a screw of a connector from being loosened and to prevent transmission power from being varied even if torsional stress is applied by fitting a bearing coaxially with an optical fiber and relatively rotating an outer peripheral part, the fiber, a protection tube, and so on. CONSTITUTION:The bearing 5 is fitted so as to cover the whole or a part of an inner connector 3 and the center of the bearing 5 is made to coincide with that of the fiber 1 so that inner and outer wheels 6, 8 are optionally and relatively rotated. If external force in the circumferential direction, i.e. twisting force, is applied to the protection tube 2, the inner connector 3, the protection tube 2 and the optical fiber 1 are rotated in a direction for loosening the twisting force. Thereby, twisting stress is not transmitted to the outer connector 4 and the outer connector 4 is not rotated, so that a nut 19 is not loosened. Consequently, the axis of an input end face 22 is not sheared, transmission power is not varied and the connector part can be prevented from increasing heat loss.
