Abstract

Secondary ion mass spectroscopy (SIMS) and Auger electron spectroscopy (AES) depth profiles of a double layer structure of AlAs in GaAs were compared to show the application of mixing-roughness-information (MRI) depth model to quantitative reconstruction of in-depth distribution of composition. Identical sputtering conditions were used to depth profile GaAs\AlAs reference sample consisting of two layers of AlAs separated by 44 monolayer of GaAs matrix. A marked nonlinearity between concentration and intensity was noticed on quantification using dimer (Al₂⁺) and trimer (Al₃⁺) ions with the main effect caused by simple mass action law probability of cluster ion formation.
