Abstract:
Multifunctional electroactive copolymers are provided. The copolymers may be A-B-A triblock copolymers, brush-type graft copolymers, or variations thereof. In a preferred embodiment, the copolymers are "dual use" in that they comprise both a light emitting segment and a charge transport segment. Methods of synthesizing the novel electroactive copolymers are provided as well, as are opto-electronic devices, particularly LEDs, fabricated with the novel copolymers.

Abstract:
An approach is presented for designing a polymeric layer for nanometer scale thermo-mechanical storage devices. Cross-linked polyimide oligomers are used as the recording layers in atomic force data storage device, giving significantly improved performance when compared to previously reported cross-linked and linear polymers. The cross-linking of the polyimide oligomers may be tuned to match thermal and force parameters required in read-write-erase cycles. Additionally, the cross-linked polyimide oligomers are suitable for use in nano-scale imaging.
Abstract:
PROBLEM TO BE SOLVED: To provide a porous dielectric material used in electronic devices such as integrated circuits. SOLUTION: Crosslinked particles are manufactured by activating crosslinkable groups in synthetic polymer molecules. The crosslinkable groups are inert until activated and, when activated, undergo an irreversible intramolecular crosslinking reaction to form crosslinked particles. Further, the crosslinked particles are intermolecularly deactivated to the polymer molecules under the crosslinking condition. The crosslinked particles are also intermolecularly deactivated each other under the crosslinking condition. The resultant crosslinked particles having the decomposition temperature lower than that of the host-matrix material is mixed with the host-matrix material, heated up to the decomposition temperature of the crosslinked particle to irreversibly decompose the particles into the porous dielectric material.

Abstract:
PROBLEM TO BE SOLVED: To improve mechanical toughness and polishing characteristics by allowing a dielectric composition for creating an integrated circuit to contain a methylsilsesquioxan and a photosensitive base or a heat-sensitive base product. SOLUTION: In a multilayer integrated circuit device, the lower layer of insulated flattening metal circuit lines 4 is allowed to function as a substrate 2, a perpendicular metal stud 8 is formed in the substrate 2, and at the same time a dielectric material 6 is buried between the flattening metal circuit lines 4 for formation. The dielectric material 6 contains tetraalkoxysilane and tetraethoxy silane, alkyl/trialkoxy, or trihalo silicate, or dialkyl/dialkoxy, or alkyl (methyl) phenylsilsesquioxan that is mixed with dihalo silicate, and a photosensitive base or a heat-sensitive base product.
Abstract:
PROBLEM TO BE SOLVED: To provide a porous dielectric material applicable to electronic devices such as integrated circuits. SOLUTION: Crosslinked particles are produced by activating the crosslinkable groups on synthetic polymer. The crosslinkable groups are inert until activated and, when activated, undergo an irreversible intramolecular crosslinking reaction to form crosslinked particles. And the crosslinked particles are inert to the polymer molecules in intermolecular crosslinking under crosslinking conditions, and are inert to each other in intermolecular crosslinking under crosslinking conditions. The thus obtained crosslinked particles having a lower decomposition temperature than that of the host matrix material are mixed with the host matrix material, and the compound is heated to the decomposition temperature of the crosslinked particles to decompose the crosslinked particles so as to produce the porous dielectric material.

Abstract:
PROBLEM TO BE SOLVED: To obtain a crosslinked particle useful for manufacturing a dielectric material used for an electronic device such as an integrated circuit. SOLUTION: The crosslinked particle is manufactured by activating a crosslinkable group in a synthetic polymer. The crosslinkable group remains inactive until it is activated and, when activated, an intramolecular crosslinking reaction occurs irreversibly and the crosslinked particle is formed. In terms of intermolecular crosslinking, the crosslinked particle is kept inactive with each other and against the polymer molecule under the crosslinking condition. COPYRIGHT: (C)2004,JPO

Stable, bulk electrical superconductors are prepared by heating mixed metal oxides in the presence of oxygen in a closed vessel in a preheated oven for 1-5 hours at 850-900 DEG C. The final oxides are in the molar ratio Tl0.6-1.1Ca2-3Ba0.75-1.25Cu2-3O(5+ delta )-(9+ delta ), where delta is less than one.
