Title: Method of cleaning surface of semiconductor wafer
Inventor: BERNARD FORNIERE
IPC: H01L21/321
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To completely remove slurry and metal particles left on the surface of a wafer after it is chemically and mechanically polished without causing damage to the surface of the wafer by a method wherein the surface of the wafer is scrubbed with alkaline colloid silica slurry whose pH is above a specific value and then scrubbed with deionized water after the wafer is mechanically and chemically polished. SOLUTION: First, a wafer is normally, chemically and mechanically polished in a CMP process 21. Then, the wafer is continuously scrubbed for cleaning with alkaline colloid silica slurry whose pH is above 10 for a short time in a cleaning/scrubbing process 22 and then cleaned with deionized(DI) water. In succession, in a standard finishing process 23, the wafer is scrubbed with the same slurry. Lastly, the wafer is rinsed with DI water and dried out in a rinse process 24. Alkaline colloid silica slurry is used in a cleaning/scrubbing process 22, whereby the contaminated wafer can be very effectively cleaned.

Filed: 1990-05-09
Abstract: PURPOSE:To reduce the resistance of wirings formed across a step by so forming a lower polycrystalline silicon relatively thick to be etched back as to bury a groove generated between first wirings, flattening the surface, and depositing to cover a metal silicide. CONSTITUTION:A polycrystalline silicon 7 is so deposited sufficiently thicker than the half of the width of a grove 6 to bury the groove 6 by a vapor growing method. Then, the silicon 7 is entirely etched back to be reduced in entire thickness, and the surface is flattened. the etching back is desirably a dry etching method using halogen gas in view point of controllability as compared with a wet etching method. Then, as the metal silicide, WSi 8 is deposited by a sputtering method. Thus, thickly formed polycrystalline silicon is etched back to eliminate a step existing on a base to be flattened. As a result, the WSi can be formed as substantially flat wirings. Accordingly, a wiring length can be shortened by an amount corresponding to the elimination of the step to reduce a wiring resistance.

Title: Torque control device for internal combustion engine
Inventor: ANDO KEN
IPC: F02D41/10
Filed: 1994-05-31
Abstract: PURPOSE:To improve reliability of reduction effect of vehicle vibration caused by twist vibration, and suppress deterioration of acceleration to 4 minimum level. CONSTITUTION:When an acceleration pedal 57 is stepped down for accelerating a vehicle rapidly, an output torque is changed rapidly, so that twist vibration is generated in the driving system such as a crank shaft 40. In an electronic control unit(ECU) 71, a torque control time corresponding to a vehicle vibration period is calculated on the basis of a maximum rotating speed change amount according to a twist vibration amount, a fuel injection amount from a fuel injection pump 1 is controlled for the control time, torque correction is controlled, and correction control is not carried out after passing a control period. Therefore, the control period is varied according to the magnitude of the twist vibration amount, so that torque control is carried out in association with a continuing period. It is thus possible to prevent the completion timing of torque control from being sooner or later.

Abstract: PURPOSE:To decide the flocculation reaction of settled particles easily and accurately by feeding test liq. contg. particles into a vessel for decision provided with a sloped bottom surface formed regularly with level differences permitting the formation of stable base layers for said particles. CONSTITUTION:A vessel 5 for decision is formed with a pipeline 8 of a rectangular shape in section between an inflow port 6 and an outflow port 7. A sloped passage 9 is provided to a part of the pipeline 8, and level differences 10 are formed on the bottom surface of said passage 9. If test liq. contg. particles is kept still for a constant time after said liq. is introduced through the port 6 into the pipeline 8, stable root layers are formed in the recesses of the level differences 10 when particles are going to flocculate, and the particles falling onto said layers flocculate and deposite. When the particles do not flocculate, only the particles of the root layers remain on the slope, and the other particles deposit on the lower part of the slope. Therefore the flocculation and non-flocculation are decided easily and accurately be measuring the difference in the concn. of the slopes.
