Title: Photosensitivity evaluating method for photographic sensitive body
Inventor: NARITA MITSURU
IPC: G03G5/00
Filed: 1990-06-20
Abstract: PURPOSE:To estimate the photosensitivity of the photosensitive body at the stage of the formation of a charge generating layer by measuring the light reflectivity of the surface of a conductive base and the light reflectivity of the surface of the base body through the charge generating layer. CONSTITUTION:The surface of the conductive base body is irradiated with light having specific wavelength first and the reflectivity R1 is measured. Then the charge generating layer is formed on the base body by coating, the base body surface is irradiated with light having the same wavelength through the charge generating layer, and the reflectivity R2 is measured. Then the photosensitivity of the photosensitive body which is obtained from the value of the reflectivity difference R1-R2 is estimated and evaluated. The difference R1-R2 is larger and larger as the quantity of half-attenuation exposure is smaller and smaller, namely, as the photosensitivity is higher and higher. Therefore, the photosensitivity of the photosensitive body which is obtained at the stage of the formation of the charge generating layer can be estimated and evaluated.

Title: Manufacture of semiconductor device
Inventor: ICHINOSE SHUJI
IPC: H01L21/3205
Filed: 1993-06-30
Abstract: PURPOSE:To execute a planarization at a chip level by using a second insulating film having an excellent burying property against the local grooves of a first insulating film and forming a film thinly on this surface and flattening the surface. CONSTITUTION:When the upper layer part of a first insulating film 3 is ground off by mechnochemical polishing, voids 4 in this first insulating film appear as local grooves 4 on the surface of the ground first insulating film 3. And the local grooves are filled with a second insulating film and the surface is flattened, when the second insulating film O3-TEOS for example, is formed thinly on the first insulating film 3, since the second insulating film has an excellent burying property against the local grooves 4'. Consequently, it becomes possible to remove defects such as easily-crackable, etc. Besides, it becomes possible to execute a planarization at a chip level effectively.

Abstract: PURPOSE:To prevent the corrosion of a bonding pad, etc. for a pellet by forming a damp-proof resin layer in thickness, which does not exceed the height of the upper end of a nail head section, to the whole upper surface of the pellet loaded on a resin seal type semiconductor device. CONSTITUTION:Silicone gel is applied onto the whole upper surface of a passivation film 6 in extremely thin thickness, thickness which does not exceed the upper end 5b of a nail head section 5a as a wire connecting section, and a resin layer 9 is shaped. Consequently, clearances from which an aluminum wiring 8 is exposed are also filled with silicone gel. Accordingly, even when the resin layer 9 is shaped in extremely thin thickness, silicone gel has excellent damp-proofing, thus preventing the intrusion of a corrosive substance such as moisture from the clearances among the side end section of the nail-head section 5a and the periphery of the boring section for the passivation film 6.

Title: Synthetic method of compound containing sulfur
Inventor: IWASAKI KOUZOU
IPC: C07D277/16
Filed: 1980-11-19
Abstract: PURPOSE: To obtain the aimed substance in high yield with minimized side reactions in reacting a sulfuric ester of an aminoalkyl alcohol with carbon disulfide to obtain 2-mercaptothiazoline, by adding an alkali hydroxide in portions to the reaction mixture.  
     CONSTITUTION: An aminoalkyl sulfuric ester of formulaIis dissolved in an equivalent amount of an aqueous solution of an alkali hydroxide, and carbon disulfide in an amount equimolar with the sulfuric ester is then added to the solution and reacted at the boiling point of the carbon disulfide or below to form an alkyl sulfuric ester of dithiocarbamic acid expressed by formula II fully. The reaction is then carried out by adding or dropping the remaining alkali hydroxide in portions to the reaction mixture to afford a compound expressed by formula III (R 1 , R 2 , R 3  and R 4  are H or lower alkyl).  
     EFFECT: Side reactions, e.g. decomposition, can be minimized due to no contact of the aminoalkyl sulfuric ester and 2-mercaptothiazoline with a large amount of the alkali hydroxide under heating for a long time.

Abstract: PURPOSE: To restrict formation of iron oxyhydroxide, by measuring an electrical conductivity of a ferritizing reaction solution to detect the ferritizing reaction rate, and controlling the reaction rate so as to increase with time.  
     CONSTITUTION: To waste water containing heavy metal ions is added iron (II) sulfate and the pH is adjusted at about 10W12. This water is charged as a reaction solution into a reaction vessel 2 and agitated with a stirrer 3, and air is blown from a sparger 5 by the operation of a blower 4. The reaction solution is oxidized by this air blow. A part of the oxidized solution is extracted by a sampler 6, and the ferritizing reaction rate is detected by a detector 7. This detector is preparatively set so that the ferritizing reaction rate in each reaction period will increase gradually with time. The amount of air blow is controlled by the operation of an air control valve 8, and the agitation speed is controlled by the operation of a motor 9 of the stirrer 3, so that the reaction rate is maintained at a preset value at the detector 7. When the reaction rate reaches 100%, the treated water is discharged through a discharge valve 10.
