Filed: 1987-01-20
Abstract: PURPOSE:To miniaturize a semiconductor element, by effectively increasing the capacitance of a capacitor by a conducting layer, which is formed by introducing impurities is the surface of a dielectric film constituting the capacitor by an ion implantation method. CONSTITUTION:An N-type diffused region 2 is formed on a P-type semiconductor silicon substrate 1. A first dielectric film 4 is formed on the diffused region 2. A second dielectric film 5 is formed on the first dielectric film 4. A conducting layer 6 is formed by introducing impurities in the surface of the second dielectric film 5. Electrodes 7 and 8 are formed on the conducting layer 6. The effective capacitance of a capacitor in the dielectric films can be controlled with the energy and the dose amount of the implanted impurity ions. Therefore it is not required to make the dielectric films more thinner. Pinholes are not yielded because of the thin film configuration. Breakdown strength is not decreased, and the yield rate in manufacturing and the reliability in quality are not decreased. Thus the semiconductor element can be miniaturized.

Filed: 1981-01-29
Abstract: PURPOSE: To obtain a glass bottle provided with both mechanical strength and chemical durbaility by simultaneously subjecting the outer surface of a glass bottle to ion exchange and the inner surface to dealkalization.  
     CONSTITUTION: In order to ion-exchange only the outer surface of a molded matrix glass bottle after a slow cooling process, a high concn. aqueous soln. of a salt mixture of potassium chloride with potassium nitrate or the like is applied to the outer surface. In order to dealkalize the inner surface of the bottle, gaseous SO 2 , ammonium chloride, ammonium sulfate or the like is charged into the bottle. This bottle is shifted into a heat treating furnace heated to a temp. at which it is not damaged, and heat teeatment is carried out as shown by the diagram. Thus, separate reactions proceed on the inner and outer surfaces. At this time, the furnace is filled with gaseous SO 2  for the dealkalization, yet when the ion exchange proceeds simultaneously, unfavorable influence is hardly exerted on the ion exchange.

Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To realize a manufacturing method for a semiconductor light emitting element which can reduce a crystal defect and which can enhance an element characteristic. SOLUTION: At a substrate temperature as a first temperature which is higher than a second temperature at which an n-AlGaInP clad layer 3 is to be grown, an n-GaAs buffer layer 2 is grown on an n-GaAs substrate 1. As a result, the migration of Ga which constitutes the n-GaAs substrate 1 and the n-GaAs buffer layer 2 is promoted, and a crystal defect is reduced. In addition, oxygen which is stuck to the n-GaAs substrate 1, a substrate holding implement 12 and a member in the circumference of the substrate holding implement 12 is evaporated, and the n-AlGaInP clad layer 3 is then grown. As a result, when a light emitting layer is grown, the oxygen is not evaporated from the n-GaAs substrate 1, the substrate holding implement 12 and the member in the circumference of the substrate holding implement 12.  Consequently, it is possible to prevent that oxygen which forms the center of a light non-emitting recombination creeps to then-AlGaInP clad layer 3.

Abstract: PURPOSE:To suppress a forward voltage drop to a small value by composing a reverse connection preventing circuit, at the input section of a power supply built in a sensor such as a photoelectric sensor, etc., of an FET and a Zener diode. CONSTITUTION:In a photoelectric sensor, etc., for detecting a person or an article, a sensor 21 is formed of a power supply 28 and a sensor circuit 29. A surge absorber 23 and a reverse connection preventing circuit 24 are provided at the power supply connecting section of the sensor 21. If a power supply is externally connected to a DC power supply input terminal 22 erroneously in polarity, the potential at the gate electrode of a P-channel FET 25 becomes higher than that of a source electrode. Accordingly, the FET 25 is not conducted, and the circuit 21 is protected against damage due to the flow of a reverse polarity current. When the polarity of the terminal 22 is normal, the voltage drop of the circuit 24 becomes about 0.1V, and hence the lower limit of the voltage range of the external supply power source can be lowered.
