摘要： An improvement is proposed in the cleaning treatment of semiconductor silicon wafers in which the conventional step of cleaning with an aqueous solution of an alkali is replaced with a cleaning treatment with a temporarily alkaline pure water which is produced electrolytically by the application of a DC voltage between a cathode and an anode bonded to the surfaces of a hydrogen-ion exchange membrane so that the alkaline cleaning treatment can be performed under mild conditions so as to eliminate the troubles due to formation of COPs unavoidable in the conventional process. In addition, the pure water rinse following the alkali cleaning of the wafers before transfer to the succeeding acidic cleaning step can be omitted to greatly contribute to the improvement of productivity. The apparatus used therefor comprises a rectangular vessel divided into a central cathode compartment, in which the wafers are held in a vertical disposition within an up-flow of pure water, and a pair of anode compartments by partitioning with a pair of hydrogen-ion exchange membranes, on both sides of which a cathode plate and anode plate are bonded.

摘要： Disclosed is a sintered nickel positive electrode that has an expanded usable range to a low charging region by using nickel hydroxide having a particular crystal structure as a main component of a positive electrode active material.In the sintered nickel positive electrode of the invention, a nickel sintered substrate is filled, through a plurality of impregnation steps, with a positive electrode active material containing nickel hydroxide (β-Ni(OH)2) as a main component. In addition, the nickel hydroxide (β-Ni(OH)2) has an integrated intensity ratio of a peak intensity in a (001) face of 1.8 or more with respect to a peak intensity in a (100) face, where the peak intensities are determined by X-ray diffraction analysis, while an integrated intensity ratio of a peak intensity in a (001) face with respect to a peak intensity in a (100) face is about 1.5 in the related art. Using the nickel hydroxide having an integrated intensity ratio of the peak intensity in the (001) face of 1.8 or more with respect to the peak intensity in the (100) face enables high-rate continuous discharge in a low charging region.
