    摘要: Methods and compositions for depositing a metal containing thin film on a substrate comprises introducing a vapor phase metal-organic precursor into a reaction chamber containing one or more substrates. The precursor has at least one β-diketiminato ligand, and has the general formula: M(R1C(NR4)CR2C(NR5)R3)2Ln wherein M is a metal selected from nickel, cobalt, ruthenium, iridium, palladium, platinum, silver and gold. Each of R1-5 is an organic ligand independently selected from H; and a C1-C4 linear or branched, alky group, alkylsilyl group, alkylamide group, alkoxide group, or alkylsilylamide group. Each L is independently selected from: a hydrocarbon; an oxygen-containing hydrocarbon; an amine; a polyamine; a bipyridine; an oxygen containing heterocycle; a nitrogen containing heterocycle; and combinations thereof; and n is an integer ranging from 0 to 4, inclusive. A metal containing film is deposited onto the substrate, while the substrate is maintained at a temperature between about 100° C. and about 500° C.

    摘要: Disclosed are hafnium- and zirconium-containing precursors and methods of providing the same. The disclosed precursors include a ligand and at least one aliphatic group as substituent selected to have greater degrees of freedom than the usual substituents. The disclosed precursors may be used to deposit hafnium- or zirconium-containing layers using vapor deposition methods such as chemical vapor deposition or atomic layer deposition.

    摘要: Methods and compositions for depositing high-k films are disclosed herein. In general, the disclosed methods utilize precursor compounds comprising Ta or Nb. More specifically, the disclosed precursor compounds utilize certain ligands coupled to Ta and/or Nb such as 1-methoxy-2-methyl-2-propanolate (mmp) to increase volatility. Furthermore, methods of depositing Ta or Nb compounds are disclosed in conjunction with use of Hf and/or Zr precursors to deposit Ta-doped or Nb-doped Hf and/or Zr films, The methods and compositions may be used in CVD, ALD, or pulsed CVD deposition processes.
