    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.

    摘要: A thin film structure is formed that includes hafnium silicon oxide using an atomic layer deposition process. A first reactant including tetrakis ethyl methyl amino hafnium (TEMAH) is introduced onto a substrate. A first portion of the first reactant is chemisorbed to the substrate, whereas a second portion of the first reactant is physorbed to the first portion of the first reactant. A first oxidant is provided onto the substrate. A first thin film including hafnium oxide is formed on the substrate by chemically reacting the first oxidant with the first portion of the first reactant. A second reactant including amino propyl tri ethoxy silane (APTES) is introduced onto the first thin film. A first portion of the second reactant is chemisorbed to the first thin film, whereas a second portion of the second reactant is physorbed to the first portion of the second reactant. A second oxidant is provided onto the first thin film. A second thin film including silicon oxide is formed on the first thin film by chemically reacting the second oxidant with the first portion of the second reactant.
