    Abstract: The present invention provides a method of manufacturing a dielectric film having a high permittivity. An embodiment of the present invention is a method of manufacturing, on a substrate, a dielectric film including a metallic oxynitride containing an element A made of Hf or a mixture of Hf and Zr, an element B made of Al, and N and O. The manufacturing method includes: a step of forming a metallic oxynitride whose mole fractions of the element A, the element B, and N expressed as B/(A+B+N) has a range of 0.015≦(B/(A+B+N))≦0.095 and N/(A+B+N) has a range of 0.045≦(N/(A+B+N)) and a mole fraction O/A of the element A and O has a range expressed as 1.0

    Abstract: The use of atomic layer deposition (ALD) to form an amorphous dielectric layer of titanium oxide (TiOX) doped with lanthanide elements, such as samarium, europium, gadolinium, holmium, erbium and thulium, produces a reliable structure for use in a variety of electronic devices. The dielectric structure is formed by depositing titanium oxide by atomic layer deposition onto a substrate surface using precursor chemicals, followed by depositing a layer of a lanthanide dopant, and repeating to form a sequentially deposited interleaved structure. Such a dielectric layer may be used as the gate insulator of a MOSFET, as a capacitor dielectric, or as a tunnel gate insulator in flash memories, because the high dielectric constant (high-k) of the layer provides the functionality of a thinner silicon dioxide layer, and because the reduced leakage current of the dielectric layer when the percentage of the lanthanide element doping is optimized.

    Abstract: A method of forming a material over a substrate includes performing at least one iteration of the following temporally separated ALD-type sequence. First, an outermost surface of a substrate is contacted with a first precursor to chemisorb a first species onto the outermost surface from the first precursor. Second, the outermost surface is contacted with a second precursor to chemisorb a second species different from the first species onto the outermost surface from the second precursor. The first and second precursors include ligands and different central atoms. At least one of the first and second precursors includes at least two different composition ligands. The two different composition ligands are polyatomic or a lone halogen. Third, the chemisorbed first species and the chemisorbed second species are contacted with a reactant which reacts with the first species and with the second species to form a reaction product new outermost surface of the substrate.
