Secondary ion mass spectrometry (SIMS) analysis is a powerful tool for determination material composition and impurity concentration at different parts of structure with a several nm resolution and down to 10E16 cm-3 for many elements. We can estimate the thickness of nanostructure layer and exactly measure their periodicity. Optimization of the SIMS technique can improve our results. Measuring the impurity concentration profiles close to surface, we can estimate surface roughness, in our case the V-pits depth. We can measure impurity concentration profiles with high accuracy.
