Methods of manufacturing a thin film including hafnium titanium oxide and methods of manufacturing a semiconductor device including the same
摘要:
The present invention can provide methods of manufacturing a thin film including hafnium titanium oxide. The methods can include introducing a first reactant including a hafnium precursor onto a substrate; chemisorbing a first portion of the first reactant to the substrate, and physisorbing a second portion of the first reactant to the substrate and the chemisorbed first portion of the first reactant; providing a first oxidant onto the substrate; forming a first thin film including hafnium oxide on the substrate; introducing a second reactant including a titanium precursor onto the first thin film; chemisorbing a first portion of the second reactant to the first thin film, and physisorbing a second portion of the second reactant to the first thin film and the chemisorbed first portion of the second reactant; providing a second oxidant onto the first thin film; and forming a second thin film including titanium oxide on the first thin film. The present invention can further provide methods of manufacturing a gate structure and a capacitor.
