| titleOfInvention | Method for measuring content of metal oxide and metal hydroxide on metal plate surface |
| abstract | In a conventional method, when a measurement is performed using a copper plate for a semiconductor, the peak described in the literature is not detected even if the measurement is performed using an electrolytic solution described in the literature, and the chemical composition on the surface of the copper plate There is a problem that it cannot be measured accurately. In a measurement method for measuring the chemical composition of a metal plate surface from a peak potential obtained by voltammetry in which the potential of the metal plate is scanned in the electrolyte solution using a metal plate, a reference electrode, and an auxiliary electrode, the electrolyte solution includes: Contains one or more compounds selected from the group consisting of water, reducing agent (A), inorganic alkali, organic amine, and quaternary ammonium hydroxide (B), and the starting potential for scanning the potential is 0 V to − 0.5V, the return potential is -1.2V to -1.5V, the potential is scanned in the negative direction from the start potential to the return potential, then the start potential is scanned, and these scans are performed at least twice. A method for measuring the content of metal oxide and metal hydroxide on the surface of a metal plate. [Selection figure] None |
