X-ray microanalysis of thin film layered specimens containing light elementsFunded under: JRC-ADVMAT 2C
Analysis of thin film layers on bulk substrates is carried out using a technique based on the phi(rho-z) model of the depth distribution of X-ray emission. Both the composition and thickness of individual layers can be determined provided that the same element is not present in more than a single layer. The application of this method to the analysis of thin titanium-boron nitride bilayers on silicon or molybdenum substrates is discussed. X-ray intensities were measured by energy dispersive spectroscopy with a windowless or ultra thin window detector. The thickness of a 10 nm titanium layer could be estimated to within about +/- 1 nm, which is comparable with the depth resolution attainable by Auger sputter profiling.
