Metrology of thin layer deposition with combined XRR-GIXRF analysis at SOLEIL
Résumé
A new instrument called CASTOR is operated at the SOLEIL synchrotron facility and is dedicated to the characterization of thin films with thicknesses in the nanometer range. The instrument can combine X-ray reflectivity (XRR) measurements with fluorescence (XRF) acquisitions and especially total reflection X-ray fluorescence (TXRF) related techniques such as grazing incidence XRF (GIXRF). The instrument is now routinely installed on the hard X-ray branch of the Metrology beamline and reproducibility is studied as well as reference-free GIXRF analysis. Some representative examples are given to illustrate the capabilities of the setup and of the analysis.
