Title: Spectrochemical analysis method using glow discharge
Inventor: SUZUKI KENICHI
IPC: G01N21/67
Filed: 1984-03-02
Abstract: PURPOSE:To measure the composition and the thickness of a surface layer, by measuring the depth profile of the surface of a solid by spectrochemical analysis using glow discharge, converting the sputtering time into the thickness by matrix effect correction, and converting light emitting intensity into element concentration. CONSTITUTION:The depth profile of the surface of a solid, which is expressed by the sputtering time and the light emitting intensity of an element, is measured by spectrochemical analysis using glow discharge. The depth profile is divided at every unit time. The light emitting intensity of each element is converted into the concentration of each element by correcting the mutual interference effects of coexisting elements, and the composition is determind. Then, based on the determined composition, the sputtering speed is corrected, and the thickness at every unit time is determined. Based on the obtained composition and the thickness, the sputtering weight at the part of the unit time is determined. Thus the element concentration, thickness and weight of the surface layer of the solid are determined.
