Inventor: SUGANO HIROSHI
IPC: H01L29/47
Filed: 1981-08-07
Abstract: PURPOSE:To produce stabilized device having neither additional element area requirement nor degradation of reverse-direction characteristics by forming a guard ring by self alignment. CONSTITUTION:Layers of SiO29, Si3N410 and SiO211 are laminated on an n type epitaxial layer 3 which has been grown on an n<+> buried layer 2 on a p type silicon substrate 1. A resist mask 12 is then provided to etch the side of the SiO211. After plasma etching of the silicon by approximately 1mum with the mask 12 stripped, an oxide layer 4 is produced, on which p type layer 18' are deposited by boron-ion implantation using SiO211 as a mask. After this, diffusion process produces the guard ring 18 by self alignment. A metallic layer for forming Schottky barrier diode 5 and a metallic layer for interconnection 6 are then formed in the normal way with the SiO211, Si3N410 and SiO29 removed. This feature allows easy and simple prevention of degradation of reverse characteristics of the Schottky barrier diodes caused by breaking of thin films by metallic layers for interconnection without increase in element areas.

Abstract: PURPOSE:To accomplish both a magnetic field modulation system and an optical modulation system by respectively performing recording with the aid of the inversion of the magnetic field of a floating magnetic head and light irradiation in the case of the former system and with the aid of the modulation of the light irradiation in a state where the magnetic head is attracted by a coil magnet for impressing the magnetic field in the case of the latter system when recording is performed in the former or the latter system. CONSTITUTION:When recording is performed in the magnetic field modulation system, the floating magnetic head 6 floats by air flow obtained by the rotation of a magneto-optical disk 1, and information is recorded with the aid of the inversion of the direction of the magnetic field of the magnetic head main body 16 and the irradiation of laser light from an optical pickup 4. When recording is performed in the optical modulation system, the coil magnet 5 impresses the specified magnetic field on the disk 1 in a state where the head 6 is attracted by magnetic force obtained by energizing, and then, the laser light from the pickup 4 is modulated to record the information. In the case of reproducing, the laser light of low intensity is radiated from the pickup 4 and the rotating direction of the plane of polarization of reflected light is detected to optically perform reproducing. Thus, recording is performed in both systems and the head 6 does not contact with a recording medium, so that a dedicated mechanism is not necessitated.

Abstract: PROBLEM TO BE SOLVED: To eliminate signal reflection caused by mismatching of impedance by a method wherein a signal cable fixing means, which fixes a signal cable to a fixing board, and a power source cable fixing means, which fixes a power source cable to a fixing board, are provided. SOLUTION: A signal cable 2 is locked by the lock recessed part of cable fixing metal fittings 7, and the cable 2 is fixed to a fixing plate 6 by fixing screws 8 into the threaded holes of an engaging pice.
