    摘要： A first reactant gas is flowed into a CVD reaction chamber containing a heated integrated circuit substrate. The first reactant gas contains a first precursor compound or a plurality of first precursor compounds, and the first precursor compound or compounds decompose in the CVD reaction chamber to deposit a coating containing metal atoms on the heated integrated circuit substrate. The coating is treated by RTP. Thereafter, a second reactant gas is flowed into a CVD reaction chamber containing the heated substrate. The second reactant gas contains a second precursor compound or a plurality of second precursor compounds, which decompose in the CVD reaction chamber to deposit more metal atoms on the substrate. Heat for reaction and crystallization of the deposited metal atoms to form a thin film of layered superlattice material is provided by heating the substrate during CVD deposition, as well as by selected rapid thermal processing (“RTP”) and furnace annealing steps.

    摘要： A ferroelectric thin film precursor material is annealed while in an electric field. The electric field is maintained as the material cools. A partially completed integrated circuit with a ferroelectric thin film precursor material may be placed between two electrodes in an annealing apparatus and voltage sufficient to polarize the ferroelectric thin film material in the direction of the electrical field is supplied to the electrodes during the anneal and as the film cools. Alternatively, probes are connected to the electrodes of a partially completed integrated circuit device and voltage sufficient to polarize the ferroelectric material is applied while annealing the material and as it cools. The anneal may be a furnace anneal or an RTP anneal.

    摘要： Data is read out from a ferroelectric film with its remnant polarization associated with one of two possible logical states of the data and with a bias voltage applied to a control gate electrode over the ferroelectric film. The ferroelectric film creates either up or down remnant polarization. So the down remnant polarization may represent data “1” while the up or almost zero remnant polarization may represent data “0”, for example. By regarding the almost zero remnant polarization state as representing data “0”, a read current value becomes substantially constant in the data “0” state. As a result, the read accuracy improves. Also, if imprinting of one particular logical state (e.g., data “1”) is induced in advance, then the read accuracy further improves.

    摘要： A gasifier system for converting biomass to biogas includes a reaction chamber with a biomass supply port for receiving a biomass volume, a waste outlet port for discharging biomass conversion by-products, a gas inlet for receiving heated oxidizing gas, a gas outlet for discharging generated biogas and a burner manifold for distributing oxidizing gas within the chamber to react the biomass. The burner manifold includes primary tubes and secondary tubes, positioned in a vertically lower part of the chamber and configured with multiple openings or ports for dispensing the oxidizing gas, where the secondary tubes extend into, inject and evenly distribute the oxidizing gas into the biomass volume to optimize conversion to biogas.
