  • Patent number: 8911827
    Abstract: A chemical deposition method for producing a platinum thin film or a platinum compound thin film by chemical vapor deposition of an organoplatinum compound is represented by the following formula, which includes a divalent platinum atom, and hexadiene or a hexadiene derivative and alkyl anions coordinated to the divalent platinum atom. In the following formula, R1 and R2 are each an alkyl group, and may be different from each other. R3 and R4 are each a hydrogen atom or an alkyl group, and may be different from each other. The organoplatinum compound is satisfactory in stability and generates no toxic substance in film formation, and hence is satisfactory in handleability and excellent in practicability. The organoplatinum compound has a high vapor pressure, enables the film formation at a low temperature, and is useful as a CVD raw material easily forming a film on a spatial structure.

  • Patent number: 8642796
    Abstract: An object of the present invention is to provide an organoruthenium compound which has good film formation characteristics as an organoruthenium compound for chemical deposition, has a high vapor pressure, and can easily form a film even when hydrogen is used as a reactant gas. The present invention relates to an organoruthenium compound, dicarbonyl-bis(5-methyl-2,4-hexanediketonato)ruthenium (II) which can have isomers 1 to 3, wherein the content of the isomer 2 is 30% by mass or more, the content of the isomer 3 is 30% by mass or less, and the balance is the isomer 1.
