WebWe have calculated the atomistic mechanism for the HfO2 atomic layer deposition (ALD) using Hf(NEtMe)4 and H2O precursors using density functional theory. On hydroxylated Si surface, our results show overall Hf(NEtMe)4 half-reaction is exothermic by 1.65 eV with a small activation barrier of 0.10 eV. The activation barriers for water half-reaction are 0.24 … WebApr 5, 2024 · The thickness of different cycles of ALD Al2 O 3 and HfO 2 films are displayed in Fig. 8. In each of the sub figures, the thickness can be fitted linearly versus the cycle number, indicating a rather stable self-terminating feature of ALD. The GPC of ALD Al 2 O 3 is 0.110 nm ± 8%, of ALD HfO 2 is 0.106 nm ± 7%.
