IPC: H01L21/3205
Filed: 1980-11-20
Abstract: PURPOSE:To manufacture the highly reliable structure with which bonding can be performed at reduced processes for the subject semiconductor device by a method wherein a conductive film which can be bonded to the outer lead wire is formed at the pad section of the wiring layer, consisting of the material into which semiconductor ingredients are hardly penetrated, by performing a lift-off. CONSTITUTION:On the oxide film 13 of an Si substrate 12, inside of which an element was formed, a wiring layer 14 consisting of an Al alloy wherein Si and/ or cu was added, for example, is formed and after the layer 14 has been connected to the element therugh the aperture section provided on the film 13, a PSG film 15, for example, is deposited on the whole surface. Then, a resist mask 16 is provided, and after the film 15 on the pad section has been removed by performing a plasma etching, for example, a pure Al film 19 is evaporated on the whole surface. Subsequently, the resist 16 is removed, the Al film on the resist isolated by a stepped section 20 is removed (lifted off) at the same time, and a pad electrode 19 is formed. Through these procedures, the generation of punch-through of junction of the element and the connected part can be prevented and wiring processing with which wire bond will easily be performed, can be manufactured by the reduced mask processing.

Title: Semiconductor pressure sensor and manufacture of semiconductor device having it
Inventor: MATSUMI YASUSHI
IPC: G01L9/04
Filed: 1990-06-25
Abstract: PURPOSE:To improve yield bar forming diaphragm configuration and a registration mark on a silicon substrate, by polishing it until the registration mark appears from the rear of the substrate and by forming a piezo resistance element on the polished surface. CONSTITUTION:Exposed silicon is etched by about 150mum to form a diaphragm 9 and a registration mark 10. A rear of the substrate 1 whereon a polysilicon layer 30 is formed is polished and removed until an end of a V-shaped groove of the registration mark 10 appears. A diffusion resistance layer 3 which becomes a piezo resistance element is formed at a single crystal side of the substrate 1, and an Al wiring 5 and a passivation film 6 are formed. Since pattern formation of the diffusion resistance layer 3 is performed by carrying out positioning from a front side using the registration mark 10 which is exposed on a surface of single crystal of the substrate 1 in the process, accurate arrangement is realized on a specified position on the diaphragm 9. Then, the polysilicon layer 30 on the rear of the substrate is removed until the polysilicon layer 9 in a region of the diaphragm 9 disappears to complete a pressure sensor chip on a surface of the substrate 1.

IPC: B65G53/40
Filed: 1981-10-15
Abstract: PURPOSE:To prevent abrasion of a discharge valve caused by powder seal effect and control the height of powder by forming a combination of plural powder seal layers in one powder bath.

Title: Water heater
Inventor: MORISHIMA MAKOTO
IPC: F24H1/18
Filed: 1988-07-01
Abstract: PURPOSE:To prevent an abnormal rise in water temperature around an electric heater during power supply suspension to an electric heater by installing a pump which produces water flow in a circulation passage designed to circulate the water in a water tank and a pump time lag shutdown means which shuts down the power supply to said electric heater latter after having stopped te power supply to the electric heater adapted to heat the water in said circulation passage. CONSTITUTION:When a timer setting means 14 is turned on, power is supplied to a pump 7, if the temperature of hot water in a bath tub detected by an incurrent water temperature sensor 5 is lower than the temperature of hot water preset by a hot water temperature setting means 13, then a water current sensor 6 is turned on. When the sensor 6 detects the generation of water current in a circulator 3, electric power is supplied to an electric heater 8. When the temperature of hot water in a bath tub 2 has reached the preset temperature, the power supply is suspended to the electric heater 8. At the same time, a pump time lag shutdown means 16 acts and allows the power supply to the pump 7 for a specified time even after the power supply to the electric heater 8 is suspended. As a result, the remaining heat of the electric heater 8 is cooled by the water flowing in the circulator 3. The water heated by the remaining heat is not allowed to rise to the temperature to which an overheat switch 9 actuates in the circulator.

Filed: 1990-06-25
Abstract: PURPOSE:To eliminate inconvenience for monitoring the lack of recording paper and the generation of communication error by detecting the lacked state of recording paper by a recording paper leak detecting means and oscillating the detection signal of a specified frequency. CONSTITUTION:When recording paper is running out in a facsimile terminal 20, the lacked state of recording paper is detected by a recording paper lack detecting means 24 in the terminal 20, and a detection signal S24 of a specified frequency is transmitted. On the other hand, a monitoring equipment 50 transmits an activation signal through an automatic exchange 40 to the terminal 20 periodically or in an arbitrary period and receives a response signal from the terminal 20. Since the signal S24 is transmitted through the automatic exchange 40 together with the response signal in the case of this reception, the equipment 50 can detect the lacked state of recording paper in the terminal 20 by receiving the signal S24 and thus, exact remote monitor can be enabled to the lack of recording paper by raising an alarm showing the lack of recording paper.
