Abstract(in English) | In this study, we investigated the effect of oxidant sources on carbon-related impurities in atomic layer deposited (ALD)-Al2O3 by focusing on plasma-induced decomposition of ?CH3 groups which attributed in ALD precursor. We found that the C?O bonds were detected in the ALD-Al2O3 using O2 plasma instead of the C?H bonds which attributed to ?CH3 groups of trimethylaluminum. It is considered that the decomposition of ?CH3 groups was enhanced by O2 plasma, and C?O residue was generated. We concluded that the decomposition of ?CH3 groups by oxidant sources must be suppressed to reduce the carbon-related impurities in ALD-Al2O3. |
