Abstract: An object of the present invention is to provide a cleaning composition which has excellent removability of a residue (particularly, a residue after CMP) and excellent anticorrosion properties of copper; a cleaning method of a semiconductor substrate; and a manufacturing method of a semiconductor element. The cleaning composition of the present invention contains citric acid, 1-hydroxyethane-1,1-diphosphonic acid, a sulfonic acid-based surfactant, and water, in which a mass ratio of a content of the citric acid to a content of the 1-hydroxyethane-1,1-diphosphonic acid is 20 to 150, a mass ratio of the content of the citric acid to a content of the sulfonic acid-based surfactant is 70 to 1,500, and a pH is 0.10 to 4.00.

Abstract: First and second FPC fixing members 12, 13 are fixed within a boss 6 on a second axis Y, and one end of the second member 13 projects to the back of a hinge base 8. An FPC wiring fixing section 26 is fixed on the back of the base 8 on a first axis X. The fixing members pass an FPC 25 from the base 8 side to the side of a monitor 3 to hold the FPC linearly on the axis Y, and are turned integrally with a monitor mounting base 14. The fixing members curve outside the axis Y the FPC 25 that is led out in the direction orthogonal to the axis Y from the one end on the base 8 side of the second member 13 to have a deflection allowance, and fix the FPC to the base 8.

Abstract: The present invention is applicable to composite particles for composite dispersion plating used for forming a self-lubricating composite dispersion coating and a method of plating using such composite particles as well as a plating (coating) using the same. The purpose of the invention is to obtain a composite particle for composite dispersion plating which is comprised of a particle with an excellent capability of reducing the friction and a low or very low specific gravity, and a method of plating using such composite particles. In this invention, each of the composite particles includes a friction-reducing mother or core particle (1) encapsulated with shell particles (2) comprised of the same components as a base metal of a composite dispersion plating bath (5). This provides a composite particle for composite dispersion plating which is comprised of a particle with an excellent capability of reducing the friction and a low or very low specific gravity.
