Abstract

The insulating barriers in Al₂O₃ are directly measured using cross sectional High Resolution Transmission Electron Microscopy (HRTEM). It is shown how the thickness of an Al₂O₃ barrier varies with plasma oxidation time for a Co₈₁Pt₁₉/Co/Al-Al₂O₃/Ni₈₀Fe₂₀ tunneling junction. An example is also given on how the oxidation rate may be reduced significantly by changing the oxygen plasma conditions.
