    摘要: Using programmable resistance material for a matching resistor, a resistor trimming circuit is designed to reversibly trim a matching resistor to match a reference resistor. The programmable resistance materials such as metal-amorphous silicon metal materials, phase change materials or perovskite materials are typically used in resistive memory devices and have the ability to change the resistance reversibly and repeatably with applied electrical pulses. The present invention reversible resistor trimming circuit comprises a resistance bridge network of a matching resistor and a reference resistor to provide inputs to a comparator circuit for generating a comparing signal indicative of the resistance difference. This comparing signal can be used to control a feedback circuit to provide appropriate electrical pulses to the matching resistor to modify the resistance of the matching resistor to match that of the reference resistor.

    摘要: The present invention discloses a novel ferroelectric transistor design using a resistive oxide film in place of the gate dielectric. By replacing the gate dielectric with a resistive oxide film, and by optimizing the value of the film resistance, the bottom gate of the ferroelectric layer is electrically connected to the silicon substrate, eliminating the trapped charge effect and resulting in the improvement of the memory retention characteristics. The resistive oxide film is preferably a doped conductive oxide in which a conductive oxide is doped with an impurity species. The doped conductive oxide is most preferred to be In2O3 with the dopant species being hafnium oxide, zirconium oxide, lanthanum oxide, or aluminum oxide.

    摘要: A method of forming PrXCa1-xMnO3 thin films having a PMO/CMO super lattice structure using metalorganic chemical vapor deposition includes preparing organometallic compounds and solvents and mixing organometallic compounds and solvents to form PMO and CMO precursors. The precursors for PMO and CMO are injected into a MOCVD chamber vaporizer. Deposition parameters are selected to form a nano-sized PCMO thin film or a crystalline PCMO thin film from the injection of PMO and CMO precursors, wherein the PMO and CMO precursors are alternately injected into the MOCVD chamber vaporizer. The selected deposition parameters are maintained to deposit the PCMO thin film species having a desired Pr:Ca concentration ratio in a specific portion of the PCMO thin film. The resultant PCMO thin film is annealed at a selected temperature for a selected time period.

    摘要: A method is provided for patterning iridium oxide (IrOx) nanostructures. The method comprises: forming a substrate first region adjacent a second region; growing IrOx nanostructures from a continuous IrOx film overlying the first region; simultaneously growing IrOx nanostructures from a non-continuous IrOx film overlying the second region; selectively etching areas of the second region exposed by the non-continuous IrOx film; and, lifting off the IrOx nanostructures overlying the second region. Typically, the first region is formed from a first material and the second region from a second material, different than the first material. For example, the first material can be a refractory metal, or refractory metal oxide. The second material can be SiOx. The step of selectively etching areas of the second region exposed by the non-continuous IrOx film includes exposing the substrate to an etchant that is more reactive with the second material than the IrOx.
