- Abstract
- The effect of H2O and O-3 oxidants on the behavior of residual C and N-related impurities as well as Si out-diffusion and interfacial layer formation in atomic-layer-deposited La2O3 films grown at 250 degrees C were examined using in situ x-ray photoelectron spectroscopy. The silicate formation was suppressed in a La2O3 film grown using O-3 compared to that deposited using H2O, but interfacial layer growth was enhanced. The accumulation of C and N-related residues with low binding energy, which originated from incomplete reactions, was suppressed in La2O3 films grown using O-3. However, the use of O-3 resulted in La-carbonate phase in film. (C) 2010 American Institute of Physics. [doi :10.1063/1.3481377]
