Sputter Depth Profiling
By using a low-energy
sputter ion source, fitted to the Qtac100, in a
dual beam mode with LEIS analysis, high-resolution chemical
depth profiles are obtained. In contrast to SIMS, there is
no need to use reactive sputter species, which lead to
changes in sputter rate and ionization yield close to the
surface. The Qtac100 provides easy quantification
even in the first few nanometers of the profile.
