  • Publication number: 20230203645
    Abstract: Methods of forming molybdenum-containing films are provided. The methods include thermally depositing a first film on a surface of a substrate, for example, at a first temperature less than or equal to about 400° C., and thermally depositing the molybdenum-containing film (second film) on at least a portion of the first film, for example, at a second temperature of greater than about 400° C. The first film can include an elemental metal, for example, tungsten, molybdenum, ruthenium, or cobalt. The second film includes a reaction product of a molybdenum-containing precursor and a reducing agent.

  • Publication number: 20230089523
    Abstract: The disclosed and claimed subject matter relates to crystalline ferroelectric materials that include a mixture of hafnium oxide and zirconium oxide having a substantial (i.e., approximately 40% or more) or majority portion of the material in a ferroelectric phase as deposited (i.e., without the need for further processing, such as a subsequent capping or annealing) and methods for preparing and depositing these materials.

  • Patent number: 11230764
    Abstract: Methods of forming metal-containing films by atomic layer deposition are provided. The methods include delivering a metal-containing complex, a purge gas, and a co-reactant to a first substrate under sufficient conditions such that the metal-containing film selectively grows on at least a portion of the first substrate.

  • Patent number: 7638645
    Abstract: Metal(IV) tetrakis(N,N?-dialkylamidinates) were synthesized and characterized. Exemplary metals include hafnium, zirconium, tantalum, niobium, tungsten, molybdenum, tin and uranium. These compounds are volatile, highly stable thermally, and suitable for vapor deposition of metals and their oxides, nitrides and other compounds.
