摘要
Oxidation kinetics are reported for thin films of TiN, both directly exposed to a dry oxygen ambient and beneath polycrystalline Pt films of similar to 100 nm thickness. Oxygen resonance backscattering spectrometry was used to detect thin oxide layers at the Pt/TiN interface produced by oxidation annealing at 550-650 degrees C. A linear oxidation rate law was observed for the buried TiN film, indicating the oxidation rate is independent of average titanium oxide thickness. The linear rate constant had an activation enthalpy of 2.4+/-0.1 eV. (C) 1997 American Institute of Physics.
