Abstract: A liquid precursor for forming a thin film of ferroelectric metal oxide in an integrated circuit contains metal oxides in excess of the stoichiometrically balanced amount. When the precursor comprises strontium, bismuth, tantalum and niobium for forming strontium bismuth tantalum niobate, the precursor contains excess amounts of at least one of tantalum and niobium. Capacitors containing thin films of layered superlattice material made from a precursor containing excess tantalum and niobium show good polarizability and low percentage imprint after 1010 negative polarization switching pulses at 75° C., and after 109 negative polarization switching pulses at 125° C.

Abstract: Disclosed are peptide-based compositions and methods for inhibiting and modulating the actions of CXC intercrine molecules. The antileukinate peptides described inhibit IL-8, GRO and MIP2&bgr; binding to neutrophils and neutrophil activation. The peptides are particularly advantageous as they inhibit IL-8-induced enzyme release at a 25 fold lower concentration than is required to inhibit chemotaxis, which makes them ideal for treating various inflammatory diseases and disorders including, amongst others, Adult Respiratory Distress Syndrome (ARDS), cystic fibrosis and chronic bronchitis. The invention further includes methods for inhibiting tumor cell growth by employing selected members of the disclosed group of peptides to inhibit a-chemokine binding to the tumor cell.

Abstract: A tunneling transistor is provided as an effective means for miniaturization of a semiconductor integrated circuit having nonvolatile memory. An insulating layer is disposed on a silicon substrate. A source and a drain are disposed on the insulating layer, with an insulator of a few nanometers in thickness that provides a tunnel barrier being interposed between the source and the drain. A ferroelectric layer that exhibits spontaneous polarization is disposed directly above a region of the source that is adjacent to the insulator. With this construction, when the ferroelectric layer is polarized in a predetermined direction, at least a portion of the region of the source adjacent to the insulator forms a depletion region, with it being possible to vary the amount of current tunneling through the insulator depending on whether the ferroelectric layer is polarized or not.

Abstract: A thin film of ferroelectric layered superlattice material in a flat panel display device is energized to selectively influence the display image. In one embodiment, a voltage pulse causes the layered superlattice material to emit electrons that impinge upon a phosphor, causing the phosphor to emit light. In another embodiment, an electric potential creates a remanent polarization in the layered superlattice material, which exerts an electric field in liquid crystal layer, thereby influencing the transmissivity of light through the liquid crystal. The layered superlattice material is a metal oxide formed using an inventive liquid precursor containing an alkoxycarboxylate. The thin film thickness is preferably in the range 50-140 nm, so that polarizabilty and transparency of the thin film is enhanced. A display element may comprise a varistor device to prevent cross-talk between pixels and to enable sudden polarization switching. A functional gradient in the ferroelectric thin film enhances electron emission.

Abstract: A ferroelectric field effect transistor memory cell includes a thin film varistor located between the gate electrode and the ferroelectric layer. The varistor protects the ferroelectric layer from disturb voltage pulses arising from memory read, write and sense operations. A second electrode is located between the thin film varistor and the ferroelectric layer. The thin film ferroelectric is positioned over the channel of a transistor to operate as a ferroelectric gate. For voltages at which disturb voltages are likely to occur, the thin film varistor has a resistance obeying a formula R.sub.d >10.times.1/(2.pi.fC.sub.F), where R.sub.d is resistivity of the thin film varistor, f is an operating frequency of said memory, and C.sub.F is the capacitance of the ferroelectric layer. For voltages at or near the read and write voltage of the memory, the thin film varistor has a resistance obeying a formula R.sub.d <0.1.times.1/(2.pi.fC.sub.F).

Abstract: A substrate is located within a deposition chamber, the substrate defining a substrate plane. A liquid precursor is misted by ultrasonic or venturi apparatus, to produce a colloidal mist. The mist is generated, allowed to settle in a buffer chamber, filtered through a system up to 0.01 micron, and flowed into the deposition chamber between the substrate and barrier plate to deposit a liquid layer on the substrate. The liquid is dried to form a thin film of solid material on the substrate, which is then incorporated into an electrical component of an integrated circuit.
