Abstract:
1. A method of manufacturing a thin film comprising: introducing a first reactant comprising 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 comprising hafnium oxide on the substrate by chemically reacting the first oxidant with the chemisorbed first portion of the first reactant; introducing a second reactant comprising 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 comprising titanium oxide on the first thin film by chemically reacting the second oxidant with the chemisorbed first portion of the second reactant.
