Described are methods for deposition of metal-aluminum films using metal amidinate precursors and aluminum precursors. Such metal-aluminum films can include metal aluminum carbide, metal aluminum nitride and metal aluminum carbonitride films. The aluminum precursors may be alkyl aluminum precursors or amine alanes.

Atomic layer deposition (ALD) of smooth and highly conformal films of hafnium and zirconium oxides was studied using six metal alkylamide precursors for hafnium and zirconium. Water was used as an oxygen source during these experiments. As deposited, these films exhibited a smooth surface with a measured roughness equivalent to that of the substrate on which they were deposited. These films

Certain methods and apparatus relate to lined ampoules and/or 2-electron donor ligands. Metal amides are a class of coordination compounds composed of a metal center with amide ligands of the form NR2−. Amide ligands have two electron pairs available for bonding. In principle, they can be terminal or bridging. In these two examples, the dimethylamido ligands are both bridging and terminal: Trisaluminium dimer Trisgallium dimer In practice, bulky amide ligands have a lesser tendency to bridge.

Zirconium and hafnium derivatives are highly stable up to 250-300ºC and have reacted with water, ozone, and oxygen radicals. The hydrolysis reaction between Brønsted basic organometallic or metal–amide reagents with Brønsted acidic OH groups from water or metal–hydroxides may act as a controlled stoichiometric strategy for the formation of M–O–M bonds, if careful consideration of reaction conditions is employed.

The reaction was conducted under metal- and solvent-free conditions at a mild temperature (40 °C) in air, and readily precursors. We are continually adding new products for this dynamic and exciting field. Our range of products is presented in this brochure (sorted by key element) and include: • Metal alkyls • Metal alkylamides and alkylimides • Metal amidinates • Metal alkoxides •Metal β-diketonates • Metal cyclopentadienyls • Metal halides 2019-11-05 · Knapp and D.
