Title: Examination of semiconductor device
Inventor: MATSUDA SHUICHI
IPC: H01L21/60
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To facilitate chip examination by nondestructively and easily detecting bonding pad damage which cannot be externally recognized such as junction failure. SOLUTION: A chip 105 is placed on a stage 104 with the bonded surface faced down. Irradiated infrared light enters a silicon rear surface of the chip 105 then passes therethrough, and is reflected by a bonding pad rear surface of metal such as aluminum formed on the surface. Accordingly, an image by the infrared light captured by an infrared camera 106 indicates the status of the bonding pad 111 on the chip 105. As the infrared light reflected from the rear surface of the bonding bad 111 is inputted into the infrared camera 106, the flat-surface shape of the bonding pad 111 is displayed on a monitor 108.

Title: Video clamp circuit
Inventor: TSUBOIKE MITSUYOSHI
IPC: H04N5/18
Filed: 1990-04-06
Abstract: PURPOSE:To easily prevent the oscillation of a loop which might be caused by input of a noise component or absence of a video signal by providing a circuit discriminating a synchronizing signal of a video signal from the noise component and a switch closing/opening a feedback loop. CONSTITUTION:A synchronizing regeneration circuit 10 separates a synchronization component in a video signal inputted from a terminal 12 whose level is below a reference voltage and amplifies the synchronization component to form a sampling pulse. The sampling pulse closes a switch, a peak level of an outputted synchronizing signal is stored in a capacitor 11 and an envelope of a peak of the synchronizing signal being a distortion component is extracted from a terminal 13. The synchronizing signal and noise extracted by a synchronizing separator circuit 6 are given to a pulse width discrimination circuit 7, and when the pulse width of noise component is detected, the circuit 7 outputs a control signal controlling the switch 1. Upon the receipt of the control signal, a fixed bias V is fed to a video amplifier 2 to interrupt a negative feedback loop.

Filed: 1993-04-19
Abstract: PURPOSE:To make it possible to mount a connector even when a connector, which is larger than a component mounting hole, is connected to the tip of a lead wire by installing a large mounting hole which allows the connector to pass through near the component mounting hole. CONSTITUTION:A large-sized hole 13b is bored, which is adjacent to a component mounting hole 13a and enables a connector 4 to pass through. The circumference of this large-sized hole 13b is partially lapped over that of the component mounting hole 13a. More particularly, the both holes are shaped like 'a Dharma doll' (a small circle placed on top of a large circle) so that they may be communicated with each other by way of their bottleneck part 13c which is narrow in width. The opening width of this bottleneck part 13c is smaller than the outside diameter of a holder 2a and larger than the outside diameter of a lead wire 3. Even when a connector, which is larger than a component mounting hole, is connected to the tip of a lead wire, an electric component can be inserted into the equipment from the front and mounted thereto.

Title: Driving electlyte solution fof electrolytic capacitor
Inventor: MIYASAKA TETSUO
IPC: H01G9/035
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To suppress the reduction of the withstand voltage of electrolyte solution, even if solute concentration is increased and specific resistance is decreased by fusing the specified amounts of maleate or phthalic acid salt and dimethyl malonic acid into the solvent, whose main component is α- butyrolactone. SOLUTION: As the solvent, α-butyrolactone is used independently, or the material, wherein the α butyrolactone is the main component and mixed with other secondary solvent, is used. The solute is the ternary amine or the quaternary ammonium of maleic acid or phthalic acid and dymethyl malonic acid. Here, the dimethyl malonic acid has the large solubility and contributes to the reduction of specific resistance. Furthermore, two methyl groups of the dimethyl malonium acid act on the suppressing direction of ionization for the carboxyl group of maleic acid or phthalic acid. As a result, the action as strong- acidity is suppressed, and the withstand voltage of the electrolyte solution can be maintained. Furthermore, the adding amount of the dimethyl malonic acid is 1-10 wt.%.

Title: Electrophotographic direct image forming type planographic printing plate
Inventor: KOBAYASHI YOSHINARI
IPC: G03G13/28
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To obtain a planographic printing plate not causing printing stain and excellent in printing resistance even when desensitization with a phosphorus- contg. desensitizing soln. is carried out with an automated device or by manual coating by specifying the rate of formation of phosphorus on the surface of an image receiving layer in treating the surface of the layer with the desensitizing soln. SOLUTION: When the surface of an image receiving layer is treated with a phosphorus-contg. desensitizing soln., the rate of formation of phosphorus on the surface of the layer is regulated to 1.2-4.0 [K. CPS/sec], preferably 2.0-3.0 [K. CPS/sec]. The rate of formation of phosphorus is calculated by measuring the amt. of phosphorus in a formed desensitizing film by fluorescent X-ray analysis when the surface of the image receiving layer has been treated with the desensitizing soln. contg. phytic acid (inositol-hexaphosphoric ester) or its salt as an essential component. In the case of >4.0 [K. CPS/ sec], the adhesive strength of a toner image to the image receiving layer deteriorates and image defects are caused during printing. In the case of <1.2 [K. CPS/sec], printing stain is caused.

Title: Wiring formation
IPC: H01L21/311
Filed: 1992-03-18
Abstract: PURPOSE:To improve anti-corrosion property and also simplify removal of resist in resist ashing after wiring patterning. CONSTITUTION:After a wiring material layer of Al is formed on an insulation film 12 covering the surface of a semiconductor substrate 10, the wiring material layer is selectively etched by Cl gas with a resist layer 16 as a mask to form a wiring layer 14. Then ashing of the resist layer 16 is performed while plasma of F, H-containing O2 gas such as O2/CHF3/CH3OH is used and the substrate 10 is not heated. In this case since Cl components are removed in the form of HCl and also excessive H components are removed in the form of HF to suppress the production and deposition of H2O, anti-corrosion performance is improved. In addition, since the substrate is not heated, transformation and setting of the resist can be suppressed so that removal of resist is easy. Then ashing may be performed by using plasma of F-containing O2 gas such as O2/CHF3.

Abstract: PURPOSE:To enable cost reduction by the reduction of the number of components and consecutive print-out of lots of pictures by forming a printer with a floppy disk drive mounted thereto. CONSTITUTION:A read signal from a floppy disk drive 13 is fed to a decoder 14 at reproduction.

Abstract: PROBLEM TO BE SOLVED: To allow unification of a film thickness of an SOI (polycrystaline silicon) layer inside a wafer surface and miniaturization of a semiconductor device to be formed on an SOI substrate. SOLUTION: The surface 11a of a silicon substrate 11 formed in an uneven shape is covered with an insulator to make a grinding stopper layer 12 so as to bond a grinding substrate 16.
