Patent number: 6376692Abstract: There is provided a compound for the formation of a PZT film using Pb(dpm)2 where the compound has a low reactivity with Pb(dpm)2, has a thermal decomposition temperature which is lower than Zr(dpm)4 and is well soluble in a solvent such as butyl acetate and toluene. There is also provided a process for the manufacture of the compound. There is further provided a liquid composition for the formation of a PZT film using the compound. The novel compound Zr(OiPr)(dpm)3 has a sublimation pressure of 0.1 Torr/160° C. and is able to form a ZrO2 film by a CVD at 400° C. That can be prepared by the reaction of 1 mol of Zr(OiPr)4 and 3 mol of dpmH in an organic solvent followed by purifying by sublimation. A solution of Pb(dpm)2, Zr(OiPr)(dpm)3 and Ti(OiPr)2(dpm)2 dissolved in butyl acetate has a long pot life and forms a PZT film by a solution flash CVD method.Type: GrantFiled: October 5, 2000Date of Patent: April 23, 2002Assignee: Kabushikikaisha Kojundokagaku KenkyushoInventors: Hidekimi Kadokura, Yumie Okuhara

Patent number: 6258157Abstract: A liquid precursor is provided for the formation of metal oxide films comprising a mixture of two or more types of beta-diketonate ligands bound to one or more metals. A metal beta-diketonate compound having at least two different beta-diketonate ligands provided. For example, a liquid mixture was formed of the mixed aluminum beta-diketonates derived from two or more of the ligands 2,6-dimethyl-3,5-heptanedione; 2,7-dimethyl-3,5-heptanedione; 2,6-dimethyl-3,5-octanedione; 2,2,6-trimethyl-3,5-heptanedione; 2,8-dimethyl-4,6-nonanedione; 2,7-dimethyl-4,6-nonanedione; 2,2,7-trimethyl-3,5-octanedione; and 2,2,6-trimethyl-3,5-octanedione. Films of metal oxides are deposited from vaporized precursor mixtures of metal beta-diketonates and, optionally, oxygen or other sources of oxygen. This process may be used to deposit high-purity, transparent metal oxide films on a substrate. The liquid mixtures may also be used for spray coating, spin coating and sol-gel deposition of materials.Type: GrantFiled: September 9, 1999Date of Patent: July 10, 2001Assignee: President and Fellows of Harvard CollegeInventor: Roy G.
