Filed: 1989-02-08
Abstract: PURPOSE:To effectively use an area on a semiconductor chip by selecting the redundant word line of a first memory cell block by an address signal in a redundant address decoder circuit, and prohibiting the selection of the defective bit line of another memory cell block. CONSTITUTION:As the address data of the redundant address decoder circuit 2, the address of the memory cell block in which a defective memory cell exists and the address of a bit line are set, and a block is set at a selective state by sending a redundant bit line selection signal 5 to a block 0 selection circuit 3 when the address signal 1 from the outside is equal to a set address, and also, the redundant bit line 4 is selected. Meanwhile, a selection prohibiting signal 6 is sent to block 1-3 selection circuits, thereby, the selection is prohibited. Therefore, the bit line can be switched to the redundant bit line 4 of the block 0 even when the defective bit line exists in the memory cell blocks 1, 2, or 3, and thereby, the chip area of a semiconductor memory device can be compressed.

IPC: G01N23/06
Filed: 1978-03-14
Abstract: PURPOSE: To perform thickness measurement of a wide range without taking resistance changeover constitution by providing a voltage amplifier circuit having its own power source to the output part of an operational amplifier part.  
     CONSTITUTION: A voltage amplifier circuit consisting of a resistance 11, transistor 12, and resistance 13 is provided to the output side of an operational amplifier 6. Then, the radiations from a radiation source 1 transmits through the measuring object 3 and enters and ionization chamber 5 where ionization action is effected and the ionization current of the magnitude proportional to the radiation intensity is drawn out. This ionization current enters an operatinal amplifier 6 having the feedback resistance 7 of an extra high resistance value and is converted to the voltage signal of a low output impedance, after which it is supplied via resistance 11 to a transistor 12 and is converted to an optimum level with a slide resistance 16. This is then supplied to a logarithmic conversion circuit 9 and becomes the accurate thickness signal. Since the power source 14 of the voltage amplifier circuit may be voltage-set up to the allowable range of the same amplifier circuit, the resistance value of the feedback resistance 7 may be increased and the thickness of the measuring object 3 may be measured with high accuracy over a wide range.

Title: Manufacture of semiconductor device
Inventor: SAKAMOTO HIROAKI
IPC: H01L29/10
Filed: 1984-02-17
Abstract: PURPOSE:To decrease the diffusion layer steppings of the PB layer, which is formed just under the sunken recess part, to suppress an increasing of the thickness of the NB layer and to improve the electric characteristics of forward voltage drop and so forth of a semiconductor device by a method wherein the surface roughness of the surface of the semiconductor substrate at a time before the PB layer is formed on the surface is made larger in comparison with the surface roughness of the surface of the sunken recess part. CONSTITUTION:One main surface of a semiconductor substrate 11, that is, the surface of the semiconductor substrate 11 at a time when a PB layer 13 is formed by diffusing impurities, is performed a lapping using an abrasive material of #600 or thereabouts, for example. A sunken recess part 13a is formed in a part of the surface of the substrate 11, whereon a gate electrode is to be installed. As the sunken recess part 13a is formed by performing a chemical etching, the processing deformation of the surface thereof is less in comparison with that of the above- mentioned surface of the semiconductor substrate 11 and the surface roughness of the surface thereof is smaller than that of the surface of the substrate 11. Under this condition, when P type impurities are diffused from the side of the one main surface of the semiconductor substrate 11 for forming the PB layer 13, diffusion layer steppings 14a are formed just under the sunken recess part 13a. However, the diffusion layer steppings 14a are formed very small, because the diffusion rate in parts of the semiconductor substrate 11 other than a part of the substrate 11, which is located just under the sunken recess part 13a, is faster than that in the part of the substrate 11, being located just under the sunken recess part 13a, due to the difference between the surface roughnesses of both surfaces of the semiconductor substrate 11 and the sunken recess part 13a.

Abstract: PURPOSE: To prepare the title compound useful as a catalyst and an intermediate of medicines, under mild conditions, in high yield, by reacting 1,5-cyclooctadiene with phosphine at a specific molar ratio.  
     CONSTITUTION: 9-Phosphabicyclononane is prepared by reacting 1 mole of 1,5- cyclooctadiene with 1.5W5 moles of phosphine at 50W160°C under a pressure of 10W70kg/cm 2  in the presence of a radical-generating catalyst (e.g. azonitrile, dialkyl peroxide, etc.) and in the absence of O 2 . The objective compound can be selectively produced with little production of by-products, by the above combination of the molar ratio of the raw materials and the mild reaction conditions. The phosphine can be prepared by the reaction of yellow phosphorus with an alkali, however, the industrially available, by-produced phosphine can be used advantageously as the raw material.

Filed: 1986-02-13
Abstract: PURPOSE:To execute luminance conversion so that useless division or combination of luminance levels is not automatically generated by executing clustering by the luminance level based on the generation probability density of the luminance level of an original image. CONSTITUTION:A level histogram forming means 2 forms a histogram from luminance data stored in an input image storing means 1 and a probability density calculating means 3 calculates the generation probability density of respective luminance levels. A cluster dividing means 5 divides the luminance level of an image into two clusters based on a fixed threshold from the generation probability density and a cluster number deciding means 7 decides whether the number of generated clusters coincides with the previously deviced number or not to decide whether division is continued or not. In case the number of clusters coincides with the defined number, a conversion means 10 converts the luminance of a video based on the threshold stored in a threshold storing means 9 and stores the converted luminance in an output image storing mean 11.

Abstract: PURPOSE:To improve strength and weatherability by forming two layers consisting of an underlying layer and org. high-polymer layer over the entire surface of a magneto-optical recording medium formed by adhering and sticking a transparent substrate formed with an magneto-optical recording layer to another substrate by using a UV curing resin. CONSTITUTION:The two layers consisting of the underlying layer 5 and the org. high-polymer layer 6 are formed over the entire surface of the magneto- optical recording medium formed by adhering and sticking the transparent substrate 1 formed with the magneto-optical recording layer 2 to another transparent substrate 4 by using the UV curing resin 3.

Since the adhering and sticking structure is adopted to this recording medium, direct flawing of the magneto-optical recording layer 2 is prevented even if a part absent of the underlying layer 5 and the org. high-polymer layer 6 is partly generated by scratching the dust on the substrate 1 or the substrate 1.
