Title: Semiconductor device
Inventor: UCHIYAMA TOMOYUKI
IPC: H01L29/78
Filed: 1993-02-18
Abstract: PURPOSE:To control drop and variation of a threshold voltage value caused by short channel effect, for securing stable operation, by positioning the upper surface of channel area of semiconductor device, wherein a field-effect transistor of insulation gate type is formed, near the gate electrode side rather than the upper surfaces of the source area and drain area. CONSTITUTION:A resist 6 is applied on the entire surface of a substrate 2, then shaped into a pattern. With the resist 6 as a mask, RIE process is done, for forming a gate electrode 50 and gate insulation 40. With the resist 6 and the gate electrode 50 as masks, the upper part of an n<-> diffusion area 7 is cut off by a specified amount through RIE processing. With this, the upper surface 8a of a channel area 8 is nearer to the gate electrode than to the n<-> diffusion area 7, or the upper surfaces 10a and 11a of a source area and drain area, respectively. Then, difference in height between the upper surfaces 8a and 10a (11a) decides a threshold voltage VTH. So, according to a desired VTH, etching amount (difference in height) may be decided.

Title: Bubble-supply method in long waterway-type catalytic aeration vessel and apparatus therefor
Inventor: NIIMI TADASHI
IPC: C02F3/06
Filed: 1981-04-13
Abstract: PURPOSE: To remarkably enhance filthy water-purifying efficiency, by letting filthy water flow from one end to the other end of a catalytic aeration vessel, supplying bulky bubbles into filtering materials at the upstream side, and reducing the size of the bubbles and the feed amount of the bubbles toward the downstream side.  
     CONSTITUTION: When filthy water is let flow through an inflow opening 11, biomembranes adhere to and grow in filtering materials 5 for adhesion of the biomembranes. The biomembranes have larger fertility at a part near a filthy water-inflow line 8 and reduce their thickness and volume toward an outflow line 9. Consequently, an oxygen-demand rate is larger at the upstream side and becomes smaller toward the downstream side. When a jet stream injector 10 is driven under this condition, bulky bubbles, effective in supply of a large amount of oxygen, are formed at the upstream side. The size of the bubbles becomes smaller toward the downstream side, so that the oxygen-feed rate becomes smaller. Since oxygen-feed distribution corresponds to the growth distribution of the biomembranes, oxygen is effectively consumed with high purifying efficiency.

Abstract: PURPOSE:To realize high integration without requiring the setting of a margin width in a through hole formation part of an aluminium wiring, by covering an upper surface of a wiring conductor and a second layer insulating film with a third layer insulating film which is made of an inorganic insulating material and larger in its etching speed than a first layer insulating film. CONSTITUTION:Patterning formation of a first layer aluminium wiring 3 is performed on a field insulating film 2 of a silicon substrate 1, and a first layer insulating film 4 made of a silicon nitriding film is formed and covered with the layer 3. Next, a second layer insulating film 5 made of a silica coated film is covered with the wiring 3, and the silica coated film is etched and removed until the silicon nitriding film of the first layer insulating film 4 becomes exposed on the layer aluminium wiring. In succession, after the silicon nitriding film of the first layer insulating film 4 is removed from an upper surface of the first layer aluminium wiring 3, a third layer insulating film 6 is formed of a silicon oxidizing film, and a through hole is formed on the upper surface of the first layer aluminium wiring 3. Since the layer insulating films for the first and third layers are provided with selectivity to the similar etching agent, even in the case of position shifting the opening part stays on the first layer insulating film and do not penetrate to the lower part.

Abstract: PURPOSE: To enable to perform correct AD conversion, by providing the level set circuit constituting the envelope of one side of the signal to the output signal from the data read-in circuit.  
     CONSTITUTION: Between the data read-in circuit and the AD conversion circuit, the level set circuit 14 is provided. The circuit 14 moves the price signal which moves positive or negative than the average level with the reflection rate of commodities or AC coupling, to one side independentry of diffractive ratio of the commodities, to perform more correct AD conversion. When the commodities have lower diffractive ratio, the signal (b) is formed to the input 61 signal (a) of the circuit 14 at the envelope circuit 63, and it is inputted to the differential amplifier 62, then the output 64 moves positive by taking V ref  as the basis (c). When the commodities have higher diffractive ratio, the output 64 moves positive by taking V ref  as reference (f), and in the both cases, since the movement to negative side can be made by replacing the input of the amplifier 62, by using the circuit 63 for only one side, one directional movement can be made.
