Title: Semiconductor device
Inventor: HASEGAWA HITOSHI
IPC: H01L27/10
Filed: 1985-11-20
Abstract: PURPOSE:To enhance the integration and the quality of a semiconductor device having a capacitor by forming a silicon oxide film and a nitride film between a lower electrode and a metal oxide film to prevent a high dielectric constant metal oxide film from deteriorating. CONSTITUTION:An SiO2 film 14 is positively formed on a lower electrode 8, and an Si3N4 film 15 is formed thereon. Thus, a boundary between the film 15 and the electrode 8 is stabilized by excluding the formation of an unknown film or a natural oxide film having wrong quality to be formed, for example, in pretreating step. Since the film 15 is formed between a metal oxide film formed on the film 15 such as a Ta2O5 film 9 and the polysilicon layer 8 as the lower electrode, it can prevent the Ta film from reacting with the polysilicon layer in the step of forming the film 9 by oxidizing the Ta film and prevent the film 9 from reacting with the lower 8 by the high temperature treatment after the formation of the film 9. Therefore, it can prevent the quality such as insulation of the film 9 from deteriorating.

Title: Fine processing method for semiconductor
Inventor: IKEDA KYOICHI
IPC: H01L21/306
Filed: 1984-12-10
Abstract: PURPOSE:To execute fine process to Si substrate by using a second external power supply which can sufficiently absorb leakage current of the p-n-junction. CONSTITUTION:An Si substrate having the Pt electrode 5, p-layer 4 and n-layer 3 is immersed into the KOH aqueous solution 2 and a positive potential is applied to the substrate for the potential of liquid from the power supplies 6, 7. When a current flows to the KOH aqueous solution from the Si substrate, an SiOx is formed at the surface and SiOx is also etched by the KOH aqueous solution. When SiOx is formed quicker than the etching rate, the Si substrate becomes passive owing to the SiOx. When a voltage higher than the voltage between the solution and substrate (passive voltage) or less than such voltage is applied from the power supplies 6, 7, the p-layer 4 is selectively etched, leaving the n-layer 3. This method is effective in the range where a forward current does not flow even in the forward bias. Moreover, there is no limitation in concentration (n-layer 3) in the leaving side because of the two power supplies system, a degree of freedom of selective etching is remarkably wide and complicated and accurate fine process can be realized.

Title: Frequency discrimination circuit
Inventor: SUGIYAMA TAKAHIRO
IPC: H04L27/14
Filed: 1990-09-29
Abstract: PURPOSE:To attain frequency discrimination within a wide frequency range by comparing charges stored in two capacitors at a comparator so as to discriminate the frequency. CONSTITUTION:While a reset pulse is inputted to a reset signal input terminal 2, an N-channel MOS transistor(TR) 11 is turned on and a switch 5 is turned off. That is, a noninverting input terminal of a comparator 10 goes to an L level. On the other hand, a switch 4 is closed by the reset pulse. Then a data clock signal A inputted to a data signal input terminal 1 in this case is inputted to a time constant circuit comprising a resistor 6 and a capacitor 7, and after the reset is released, the switch 4 is opened. Since the width of the reset pulse is equal to one cycle of a data clock signal A, the charge by one clock pulse is stored in the capacitor 7. Thus, an inverting input terminal of the comparator 10 goes to an H level and a noninverting input terminal goes to an L level for a block N1, then an output signal C of the comparator 10 goes to an L level and an output signal D of a binary flip-flop circuit 13 goes to an L level.

Then a line sensor 31 picks up an image while both the lamp unit 40 and the auxiliary lamp unit 70 are lighted in order to measure a curved state of the original side S1, the size of the original and the background density.  Thus, the spread face BD is lighted so that the end face S3 causes a shadow in a direction orthogonal to the horizontal direction of the spread original BD, the shadow of the end face S3 to be produced is picked up so as to obtain the measured value of the curved spread face BD based on the picked-up image and then the image is read independently of the environmental condition.

SOLUTION: A zinc-diffused layer is formed at least in the outside of the surface layer of an Al or Al alloy pipe material for overhead earth wires. In order to form the layer, at first, a zinc plating layer with about 1-1000μm is formed on the pipe material. After that, a zinc-diffused layer is formed with 3-1000μm thickness by heating about at 200-600 deg.C for about 0.5-90 minutes. This method is applicable for Al for overhead earth wires or Al alloy strands. In this case, it is preferable that a zinc layer is formed on a roughly drawn wire of an Al or Al alloy strand, which is a mother wire of strands, heat treatment is further carried out to form a zinc-diffused layer and that drawing process is carried out after that. Moreover, this method is applicable for Al- coated steel wires.
