IPC: H01L21/3205
Filed: 1990-09-25
Abstract: PURPOSE:To prevent an interconnection from being stripped even when the interconnection is formed of a thick metal by a method wherein a groove for interconnection use is formed in an insulating film between interconnections and the interconnection by the metal is formed selectively inside the groove. CONSTITUTION:An interlayer insulating film 13, a silicon nitride film 14 and an insulating film 15 between interconnections are laminated; after that, grooves 15a, for interconnection use, which are used to grow a high-melting-point metal are formed by an etching operation. Then, a titanium film 20 having a thickness of about 1500Angstrom  is applied to the whole surface of a substrate by a sputtering operation. Then, the substrate is heated to 800 deg.C in an argon atmosphere by a rapid thermal annealing operation; it is heat-treated for about 60 seconds. The silicon nitride film 14 is reacted with the titanium film 20 coming into contact with it; a titanium nitride film 19 is formed at the lower side, and a titanium silicide film 22 is formed at the upper side. Then, this assembly is dipped in a dilute HF solution; the excess titanium film 20 is removed; the insulating film 15 between interconnections is exposed. Lastly, tungsten is grown by an SiH4 reduction method while the titanium nitride layer exposed at the bottom or the bottom side face of the grooves 15a for interconnection use is used as a nucleus; an interconnection layer 16 composed of the tungsten layer having a thickness of about 1.0mum is grown selectively.

Title: Piezoelectric actuator, infrared ray sensor, and piezoelectric light deflector
Inventor: IMADA KATSUMI
IPC: G02B26/10
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To reduce a drive voltage, increase amount of displacement, improve stability, and perform miniaturization by providing a displacement enlargement part that is on the same plane as a drive part, is connected to the drive part so that it vibrates while being synchronized with the deflection vibration of the drive part and is excited by the vibration of the drive part, and increases the vibration of the drive part. SOLUTION: When a drive voltage with a specific frequency is applied to a piezoelectric diaphragm 11, the diaphragm 11 is expanded and contracted in the longer direction with the same frequency as a driving frequency according to the drive voltage. As a result, a drive part 100 is subjected to deflection vibration with the same frequency as the driving frequency. Since the drive part 100 is fixed by the edge part of a drive part elastic thin plate 10a, a connection part 10c vibrates up and down due to the deflection vibration, and the up/down movement of a tip part at the opposite side of the connection edge of the connection part 10c is induced at a displacement enlargement part 10b due to the up/down vibration, thus vibrating the enlargement part 10b.  Also, the drive part 100 and the enlargement part 10b vibrate in harmony, the amplitude of the connection part 10c is added to the up/down vibration of the connection part 10c, and the deflection vibration of the enlargement part 10b is added.

Title: Gas insulated stationary induction electric apparatus
Inventor: INOUE TAMOTSU
IPC: H01F27/28
Filed: 1993-10-13
Abstract: PURPOSE:To increase the strength of insulation even in the case that switching surge enters a winding section by thickening the insulating cover more than the other parts as the winding for one turn from the end connected to the switch of a winding section. CONSTITUTION:An insulating cover 2 is applied equally all around an insulated copper wire 1, and the insulated copper wire 1 is wound coaxially on an insulating tube 3 so as to constitute a section 4 and a winding section. And, an insulating cover 12 is applied nearly all around, being thickened more for one turn than the insulating cover 2, on the insulated cover wire 11 at the entrance of the line path of the winding section. Hereby, the surge voltage by the switching of a disconnector is applied by the amount of only one turn of the entrance of the line path of the winding, and is not applied to other section, so even if the surge voltage accompanying the switching of the disconnector enters it, the reliability on the insulation of the winding field can be improved, and a downsized winding can be gotten.

Abstract: PURPOSE:To reduce a time for storage of minority carriers so as to attain high speed by a construction wherein a diffused layer of a reverse conductivity type formed for reduction of collector serial resistance on the lower side of a base diffused layer of some conductivity type is made to have a partial region not overlapping with the base diffused layer, in a bipolar transistor formed on a substrate of this conductivity type. CONSTITUTION:An N-type diffused layer 2 for reducing collector serial resistance, which is formed on a P-type substrate 1, for instance, is laid on the lower side of a collector layer 4a and a diffused layer 3 which are of the same N-type, and a region 13 equivalent to about 1/2 of the lower side of the collector layer 4a is formed on the substrate 1 in contact therewith so that it does not overlap partially with a P-type base diffused layer 6 when viewed in plan. In the right-half region of the N-type collector layer 4a wherein the N-type diffused layer 3 exists, minority carriers inside the collector layer 4a are confined therein by an incorporated electric field, while in the left-half region wherein the N diffused layer 3 does not exist, the minority carriers inside the collector layer 4a are drawn into the substrate 1 and an isolated diffused layer 5, since the collector layer 4a is reversely biased with the substrate 1 and the isolated diffused layer 5. Therefore, the time required for extinction of the minority carriers is reduced sharply.

Title: Logic circuit
Inventor: SAM J CHUU
IPC: H03K19/096
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To receive either a stationary input signal or dynamic input signal and to obtain satisfied operation by providing the capability of receiving either the stationary input signal or the dynamic input signal and also receiving variation of the stationary input signal during the evaluation stage of a dynamic circuit. SOLUTION: An input signal, received by the gate electrode of an NFET 32 is also received by the gate electrode of a PFET 35. The PFET 35 makes a previously charged internal node 34 recover to a high level, i.e., a positive level, when a clock input signal has a high level and the PFET 31 is off. Namely, the stationary input signal of the low level reaching the gate electrode of the PFET 35 puts the voltage level of the internal node 34 back to the high level, and an inverter 37 inverts it to the low level. Consequently, the stationary input signal possibly changes in state, even after entering the final evaluation stage of the previous charging stage, but can still make the previously charged internal node 34 recover the high level.

Abstract: PURPOSE:To compensate the dispersion of the threshold voltage of each semiconductor laser element, and to oscillate each semiconductor laser element simultaneously by separating one part of the noncurrent passing regions of each semiconductor laser element and utilizing one part of the noncurrent passing regions. CONSTITUTION:A surface emitting type semiconductor laser element 1 is composed of a laser driving section 1a projecting laser beams by injecting currents and resistance sections 1b formed along the periphery of the laser driving section 1a and opened at one points. When the dispersion of threshold voltage in the laser driving sections 1a of each semiconductor laser element 1 is kept within a range of 3.50-3.60V, the pad electrodes 14 of the resistance sections 1b are selected so that the threshold voltage of each semiconductor laser element 1 is conformed to 3.60V as the maximum value of dispersion. The four separated pad electrodes 14 may be connected to the P side electrodes 12 of the laser driving sections 1a and the common wirings 18 of wiring sections 17 respectively at that time. Accordingly, since the resistance sections 1b are shaped by utilizing the burying section of the active layer 4 of the semiconductor laser elements, the characteristics of the laser driving sections 1a are not changed by the resistance sections 1b, and the laser driving sections 1a are also formed easily through etching.
