Abstract(in English) | Room-temperature atomic layer deposition (ALD) of hafnium dioxide is developed using tetrakis(ethylmethylamino)hafnium (TEMAH) and plasma-excited water and oxygen vapor generated from a remote plasma source. The plasma-excited water and oxygen vapor is effective in oxidizing the TEMAH-adsorbed HfO2 surface while leaving OH sites on the growing surface at room temperature for further TEMAH adsorption. The growth rate is measured to be 0.26 nm/cycle at room temperature. The TEMAH adsorption and its oxidation on HfO2 were investigated by multiple-internal-refraction infrared absorption spectroscopy (MIR-IRAS). In thin work, we constructed a reaction model of the RT HfO2 ALD by MIR-IRAS and adsorption site fitting. |
