Study of elemental depth distribution

In this study we investigated depth distributions of elements in the multilayer structures of TiO2/SiO2/Si before and after ion irradiation. The samples were implanted with Ne+, Ar+, Kr+ and Xe+ ions. For each implantation the multilayer structures were irradiated by the ions with energies of 100, 150, 200 and 250 keV.

The atomic concentrations and depth distribution of elements in MOS (metal oxide semiconductor) structures have been investigated using two nuclear analytical methods: Rutherford Backscattering Spectrometry (RBS) and Elastic Recoil Detection (ERD). The elements with atomic masses in range from hydrogen up to copper were identified. Their depth profiles show that a MOS structure consists of metal (Al) layer, silicon oxide layer and a silicon substrate.
