  • PRECURSORS FOR DEPOSITION OF METAL OXIDE LAYERS OR FILMS
    Publication number: 20110184156
    Abstract: Rare earth metal precursors, for use in MOCVD techniques have a ligand of the general formula OCR1(R2)CH2X, wherein R1 is H or an alkyl group, R2 is an optionally substituted alkyl group and X is selected from OR and NR2, wherein R is an alkyl group or a substituted alkyl group. Methods of making such precursors and methods of depositing metal oxide layers from such precursors are also described.

  • Metalorganic chemical vapor deposition precursors
    Patent number: 6248928
    Abstract: A method of manufacturing a strontium &bgr;-diketonate precursor suitable for MOCVD techniques comprises the step of reacting strontium with a sterically hindered alcohol to produce strontium alkoxide, subsequently reacting the strontium alkoxide with a &bgr;-diketone to form a strontium &bgr;-diketonate alcohol adduct and removing the alcohol from the adduct.

    Assignee: Inorgtech Limited
    Inventor: Anthony Copeland Jones
  • Formation of a metalorganic compound for growing epitaxial semiconductor layers
    Patent number: 5980978
    Abstract: Semiconductor devices are prepared by growth of epitaxial layers on a substrate from metalorganic compounds of the formula MR.sub.3, R being an alkyl group, or its amine adduct. The metalorganic compound was prepared by reacting a Grignard reagent with a metal halide in an amine solvent.
    Type: Grant

  • Metalorganic compounds
    Patent number: 5886203
    Abstract: A process is provided for the production of metalorganic compounds by reacting a Grignard reagent with a Group II, Group III or Group V metal halide in a tertiary alkyl amine solvent to form a metalorganic adduct, isolating the adduct and dissociating the adduct to leave the metalorganic compound.
