“…For the quantitative analysis of a sample using confocal XRF based on PXRO, a few methods have so far been developed , Schmitz et al 2009, Sun et al 2009b, Sun et al 2010, Fittschen and Falkenberg 2011, Mazel et al 2011). The fundamental parameter approach assuming a spherical probing volume has been proposed for the analysis of paint layers.…”

Capillary X-ray optics is versatile, and it can be used with synchrotron radiation source, conventional X-ray source, laser-plasma ultrafast X-ray source, and so forth. Recently, the confocal X-ray technology based on capillary X-ray optics has become popular, and it has been widely used in X-ray fluorescence, X-ray absorption fine structure, X-ray diffraction, small-angle X-ray scattering, X-ray imaging, and X-ray scattering. This confocal X-ray technology has applications in many fields, including environmental monitoring, food science, life science, chemistry, physics, nanomaterials, nondestructive test, security check, and so on.

A semiconductor device, a microSD card, was measured by using two XRF instruments. 2D elemental images were obtained using a micro-XRF system with a spatial resolution of 10 mm. Elemental distributions of the near-surface region of the sample were clearly shown. Titanium was observed in the resin constituting the sample. Nickel and gold were observed on a terminal and localization of the sample. Elemental distribution of copper reflected the circuit structure of the measurement area that was in the neighborhood of the sample surface. Moreover, the elemental depth distributions of the sample were measured by using a confocal micro-XRF instrument. The confocal micro-XRF instrument was constructed in the laboratory with fine-focus polycapillary x-ray optics. The depth resolution of the developed spectrometer was 13.7 mm at an energy of Au Lb (11.4 keV). The elemental images obtained at near-surface by confocal micro-XRF were the same as the results obtained from 2D micro-XRF. However, different Cu images were obtained at a depth of several tens of micrometers. This indicates that microSD cards consist of a few different Cu-circuit structure designs. The elemental depth distributions of each circuit structure of the semiconductor device were clearly shown by confocal micro-XRF.
