  • Patent number: 6316651
    Abstract: The present invention is directed to the synthesis, processing and test of improved spin-on precursor materials comprising at least one Group II metal and at least one Group IV or Group V metal, useful for making thin oxide films, useful, for example, in various electronic devices, such as ferroelectric devices. For example, barium strontium titanate spin-on precursor materials are useful for making thin films of barium strontium titanate (BST) for, e.g., ferroelectric capacitors. A method is provided for fabricating electronic devices employing such Group II-Group IV (or V) oxides as the active device, using polyether acids. The method comprises: (a) providing a substrate; (b) forming a bottom electrode on the substrate; (c) depositing a solution comprising polyether acid salts of the Group II and Group IV or Group V metal ions; (d) forming the oxide film from the solution; and (e) forming a top electrode on the oxide film.

  • Patent number: 6303804
    Abstract: Metal acid salt complexes are provided comprising (1) a first metal ion consisting essentially of bismuth, and optionally, at least one second metal ion selected from the group consisting of barium, calcium, strontium, lead, titanium, tantalum, and niobium, and (2) a polyether acid. The metal acid salt complexes are prepared by combining (1) bismuth ion, and optionally, at least one second metal ion and (2) at least one of a polyether acid and a polyether acid anhydride prepared from the polyether acid. In particular, the use of a mixture of bismuth, strontium, and niobium and/or tantalum salts of the hydrophilic acid 3,6-dioxaheptanoic acid salt is described for production of ceramic thin films, such as for use in ferroelectric devices, using non-toxic solvents. As a consequence, improved electronic devices are formed from less toxic and easier handled precursors and solvents.

  • Patent number: 6124487
    Abstract: A new family of metallacycles, which are preferably zirconacycles, is characterized by having a unique halogenated substituent. The metallacycles are useful for the preparation of main group heterocycles, especially two novel families of heterocycles. The first new family of heterocycles preferably contains a halosilyl substituent. A preferred group of the second family of novel heterocycles contains a silyl group having a leaving group bonded thereto. The preferred group of these heterocycles is suitable for preparing novel organometallic complexes having a bridged bidentate heterocyclic ligand. These novel organometallic complexes may be used as catalyst components in olefin polymerization. The subject catalyst components are particularly well suited for use in the medium pressure solution process to prepare linear low density polyethylene.
