Patent number: 6369256Abstract: Volatile low melting solid Cu(II) metal complexes are provided which are capable of depositing a copper film on various substrates under CVD conditions in the absence of reducing carrier gas H2. These CU(II) metal complexes are represented by the structure formula: Cu(OCCF3R1CH2NHR2)2 wherein R1 is selected from hydrogen, C1-C4 lower-alkyl or perfluorinated C1-C4 lower-alkyl groups, e.g., CH3, and CF3, etc., and wherein R2 is C1-C6 lower-alkyl or C1-C6 lower-alkene, which may be substituted by one or more fluorine atoms, by a C1-C6 lower-alkoxy group or by a C1-C6 di-lower-alkyl amino group, provided that when R1 is CF3, R2 is other than hydrogen or methyl. A process for depositing copper film using these Cu(II) metal complexes is also provided.Type: GrantFiled: June 9, 2000Date of Patent: April 9, 2002Assignees: National Research Council of Canada, National Tsing-Hua UniversityInventors: Yun Chi, Peng-Fu Hsu, Tsung-Wu Lin, Chao-Shiuan Liu, Arthur J.

Patent number: 6355821Abstract: Methods of forming metal alkoxides and methods of forming precursor solutions of metal alkoxides suitable for the coating of glass in the manufacture of electrochromic devices are disclosed. The method of forming metal alkoxides involves dissolving the metal halide in an anhydrous solvent and reacting it with an alcohol and (together with the addition of the alcohol or subsequently) adding an epoxide, and then evaporating-off the volatile components of the reaction product to leave a solid metal alkoxide that is substantially free of halide. The alkoxide may then be dissolved in a solvent including an alcohol (preferably ethanol) containing a small proportion of water to produce a precursor solution suitable for coating glass, the coating then being hydrolyzed to form a sol-gel and then baked to remove volatile components and to yield a thin layer of metal oxide.Type: GrantFiled: July 5, 2000Date of Patent: March 12, 2002Assignee: Sustainable Technologies Australia LimitedInventors: Andrew Joseph Koplick, Susan Marie Jenkins
