Title: Manufacture of semiconductor device
Inventor: KOMADA DAISUKE
IPC: H01L29/41
Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To prevent the film of a silicon nitride film or an oxide nitride silicon film from decreasing by eliminating a reaction product being generated by the etching of an insulation film by the plasma of gas other than halogen and hence preventing the irregularities of the side wall of a groove and a hole. SOLUTION: Resist 22 is used for a mask and an insulation film 20 is etched, thus forming a wiring groove 23. Further, after the resist 22 is eliminated, a reaction product 24 being generated by etching the insulation film 20 is eliminated by the plasma of gas other than halogen. The gas other than halogen is an inactive gas simple substance or a mixed gas between an inactive gas and those other than halogen, thus preventing the inner surface of the wiring groove 23 and the inner surface of a via hole 18 below it from being etched by the halogen gas when eliminating the reaction product 24 and suppressing the occurrence of irregularities on the inner surface and at the same time preventing the via 18 from being exposed and hence preventing oxidation.

Abstract: PURPOSE: To measure the time variance of surface dielectric constant anisotropic spectrum by determining the time variance of reflection intensity for the polarized light from the irradiated surface of a crystal in the direction parallel with the incident face and the direction rotated by 90 deg. based on the irradiation in two directions of main axis. CONSTITUTION: A light emitted from a white light source 4 is condensed through a condenser lens 5 and passes through an incident optical window 6 to impinge on the surface of a substrate crystal 3. The incident light is reflected on the surface of the substrate crystal 3 and passes through an exit optical window 7 to enter into a Wollaston prism 8 where it is separated into p-polarized light and s-polarized light which are introduced, respectively, to optical fibers 10a, 10b. These lights are then passed through a spectrometer 11 and introduced to a double photodiode array 12 where the reflection intensity spectra are obtained simultaneously and individually light and s-polarized light. Another set of measuring system is prepared in order to take measurements simultaneously in two incident directions.  This constitution realizes an accurate measurement of the surface state of a growing crystal.

Title: Controlling method of pwm converter
Inventor: KUBOTA YUZURU
IPC: H02M7/155
Filed: 1981-12-18
Abstract: PURPOSE:To control the power factor of a power supply to 1 with a simple circuit constitution, by controlling the ON/OFF of a switching element constituting a converter in response to the output signal of a comparing means. CONSTITUTION:An AC input current (i) of a converter 1 increases when a thyristor or a diode at the N side conducts and decreases when a thyristor or a diode at the P side conducts. In this case, the current command pattern signal given from an arithmetic circuit 8 is applied to the input of a comparator 10 along with the current detecting signal supplied from a current detector 9. Then the thyristor or diode at the N side is turned on in case said pattern signal exceeds the prescribed value in comparison of said current detecting signal. While the thyristor or diode at the P side is turned on vice versa. As a result, the power supply current is controlled so as to have the same phase as that of the power supply voltage. Thus, it is possible to control the power factor of the power supply approximately to 1.

Title: Anti-skid controller
Inventor: SHIMIZU KOICHI
IPC: B60T8/96
Filed: 1993-08-18
Abstract: PURPOSE:To reduce an error of braking force control output due to variations in an operational characteristic by constituting a sub-processor so as to operate the braking force control output on the basis of a wheel speed operation value. CONSTITUTION:At the time of being normal, a control output operational means of a main processor 23 operates the value of braking force control output in use of a wheel speed operation value operated by its own wheel speed operational means. The control output operational means of a sub-processor 23 operates the braking force control output in use of the wheel speed operation value of the wheel speed operational means of the main processor 23, and an accumulated error due to operational characteristic variations in the wheel speed operational means is not produced in the operated result at the control output operational means of both main and sub processors 23 and 24, and thereby it results in such that merely the operational characteristic variations of the control output operational means affect the braking control output. Accordingly, when both the operated results of the control output operational means of both main and sub sprocessors 23 and 24 are compared with each other, a different portion in both of then becomes lessened, so a useless malfunction is thus preventable.
