Abstract: A modified PbZrTiO3 perovskite crystal material thin film, wherein the PbZrTiO3 perovskite crystal material includes crystal lattice A-sites and B-sites at least one of which is modified by the presence of a substituent selected from the group consisting of (i) A-site substituents consisting of Sr, Ca, Ba and Mg, and (ii) B-site substituents selected from the group consisting of Nb and Ta. The perovskite crystal thin film material may be formed by liquid delivery MOCVD from metalorganic precursors of the metal components of the thin film, to form PZT and PSZT, and other piezoelectric and ferroelectric thin film materials. The thin films of the invention have utility in non-volatile ferroelectric memory devices (NV-FeRAMs), and in microelectromechanical systems (MEMS) as sensor and/or actuator elements, e.g., high speed digital system actuators requiring low input power levels.

Abstract: A non-volatile storage cell manufactured in a standard CMOS process in silicon on insulator is described. The cell is manufactured in a standard single polysilicon layer CMOS process applied to silicon on insulator starting substrates. Two versions of the cell are described with distinct mechanisms for writing onto a floating polysilicon layer storage node. The basic cell comprises crossed N- and P- transistors which share a common channel region and a common floating gate over the channel. Current in the channel results in charge injection through the gate oxide and onto the polysilicon gate conductor where it is permanently stored. Since both N and P type transistors are available, charge of both polarities can be injected. Application of a voltage to either of the transistors results in a current or voltage which is used to perform the reading function. Multiple variations of the cell and its operation are also described along with unique applications of the cell.

Abstract: The invention relates to a method for producing a cellulose solution in an aqueous amine oxide, preferably N-methyl-morpholine-N-oxide, for processing to form cellulosed moulded bodies according to the Lyocell method, whereby said solution has an increased thermal stability. Cellulose is suspended in an aqueous amine oxide and the suspension is converted into the cellulose solution. The inventive method is characterised in that the base use of the cellulose used for producing the solution and of the optionally used additives is detected in a dispersion in aqueous amine oxide solution and in that the cellulose solution is formed by adding a base quantity which matches the detected own consumption of the cellulose and optionally the additives. Cellulose solutions having a stability which is essentially independent from the provenance of the used cellulose can he formed.

Abstract: A tamponade device for controlling post-partum hemorrhage includes an inner drain tube co-axially encircled by an inflatable balloon. The device is inserted into the uterine cavity, and the balloon is distended with a medium supplied with sufficient pressure and volume to apply even pressure along the surface of an interior uterine wall. With the application of such pressure, bleeding is stopped as evidenced by a cessation of blood draining from the inner drain tube. The inner tube includes a drainage port at an inserted end for draining blood and other fluids from the interior of the uterine cavity. An integral valve and medium insufflation and supply tubes operate to control inflation and deflation of the balloon. The supply tube co-axially encircles the drain tube to define a thin passageway between an inner surface of the supply tube and an outer surface of the drain tube. Perforations in the supply tube allow the medium to pass from this passageway in order to distend the balloon.

The cell 10 is manufactured in a standard single polysilicon layer CMOS process applied to silicon on insulator 30 starting substrates. The variable capacitor cell 10 combined with a non-volatile mechanism for programming the tuning range of the varactor 10 results in a varactor 10 which can be tuned and adjusted in an on-chip and purely electronic fashion. The basic variable capacitor cell 10 comprises a floating gate MOS variable capacitor, CMOS, in series with a metal to floating gate fixed capacitor CM/FG.

Abstract: A balloon article, e.g., for an in vivo lumenal procedure, formed of a UV cross-linkable polyurethane material that is partially cross-linked to an extent providing a desired expansibility and/or compliant character to the balloon. The degree of cross-linking is selectively modified by the degree of UV exposure to which the balloon article is exposed, and/or the relative proportion of the cross-linking agent, to achieve corresponding product characteristics ranging from semi-compliant to non-compliant polyurethane film properties, including low creep/semi-compliant films.

Abstract: A capacity increase and/or pressure decrease of gas in a gas storage and dispensing vessel is achieved by use of a physical adsorbent having sorptive affinity for the gas. Such approach enables conventional high pressure gas cylinders to be redeployed with contained sorbent, to achieve substantial enhancement of safety and capacity.

Abstract: A method for adapting the volume of a collar bag (1) that is partially filled with bulk material, whereby the collar (3) of said bag is formed by two opposite-lying outwardly bent edge strips (5) and two opposite-lying inwardly bent second edge strips (7), to the volume of the bulk material contained in said bag (1). The invention is characterized in that the first edge strips (5) are pulled apart, whereby the wall of the bag is drawn out of the upper unfilled part of the bag over the folded edges (6) and into the collar (3) or the cross-section of the bag is reduced by pressing the opposite-lying larger parts of the wall. The invention also relates to the collar bag (1) and the device to carry out the above-mentioned method.

Abstract: A method is provided for promoting adhesion of CVD copper to diffusion barrier material in integrated circuit manufacturing. The method uses a two-step CVD copper metallization process. Following deposition of a diffusion barrier layer on the IC substrate, a first layer of CVD copper is deposited on the barrier material. The first layer is preferably thin (less than 300 Å) and deposited using a precursor which yields an adherent conforming layer of copper. The suggested precursor for use in depositing the first layer of CVD copper is (hfac)Cu(1,5-Dimethylcyclooctadiene). The first layer of CVD copper serves as a “seed” layer to which a subsequently-deposited “fill” or “bulk” layer of CVD copper will readily adhere. The second copper deposition step of the two-step process is the deposit of a second layer of copper by means of CVD using another precursor, different from (hfac)Cu(1,5-Dimethylcyclooctadiene).

Abstract: Copper pyrazolate precursor compositions useful for the formation of copper in semiconductor integrated circuits, e.g., interconnect metallization in semiconductor device structures, as an adhesive seed layer for plating, for the deposition of a thin-film recording head and for circuitization of packaging components.

Such precursors are usefully employed for liquid delivery chemical vapor deposition of copper or copper-containing material on a substrate.
