  • Publication number: 20070182545
    Abstract: A disclosed wireless remote control apparatus includes a sensor, such as a capacitive sensing plate, and measurement circuitry coupled to the sensor. The measurement circuitry takes real time measurements of an electrical parameter from the sensor. The parameter, such as a capacitance or charge on the plate that relates to an electrical field in the vicinity of the sensor, represents a detection of position or movement of a member within a substantially continuous range in proximity to the sensor. In an example of a ring embodiment of the remote control device, the sensor detects position and/or movements in relation to the operator's finger. The remote control apparatus includes a wireless transmitter for wireless transmission of encoded messages and a controller. The controller controls the transmitter, to set durations of intervals between the message transmissions as a function of the measurements of the electrical parameter.

  • Publication number: 20070175321
    Abstract: Systems and methods are disclosed for providing wireless remote control of devices, where the sensing/transmitting device is worn by, or affixed to, the operator, and responds in real-time to position or movements. The technology enables the operator to control remote devices, even while the operator is engaged in other activities. For an exemplary musical performance application, the remote control apparatus may take the form of a normal sized ring worn on a finger of a hand that the musician uses to play a musical instrument. The ring senses position or movement, e.g. of one or more fingers of the hand. In the examples, the remote control apparatus uses a capacitive measurement technique to measure an electrical field generated in the vicinity of the hand indicative of position. The musician or operator can finely control a device with the system, e.g. to provide nuanced control of audio effects during the performance.

  • Publication number: 20070134417
    Abstract: A method of forming an iridium-containing film on a substrate, from an iridium-containing precursor thereof which is decomposable to deposit iridium on the substrate, by decomposing the precursor and depositing iridium on the substrate in an oxidizing ambient environment which may for example contain an oxidizing gas such as oxygen, ozone, air, and nitrogen oxide. Useful precursors include Lewis base stabilized Ir(I) ?-diketonates and Lewis base stabilized Ir(I) ?-ketoiminates. The iridium deposited on the substrate may then be etched for patterning an electrode, followed by depositing on the electrode a dielectric or ferroelectric material, for fabrication of thin film capacitor semiconductor devices such as DRAMs, FRAMs, hybrid systems, smart cards and communication systems.

  • Publication number: 20070111533
    Abstract: A method and composition for removing silicon-containing sacrificial layers from Micro Electro Mechanical System (MEMS) and other semiconductor substrates having such sacrificial layers is described. The etching compositions include a supercritical fluid (SCF), an etchant species, a co-solvent, and optionally a surfactant. Such etching compositions overcome the intrinsic deficiency of SCFs as cleaning reagents, viz., the non-polar character of SCFs and their associated inability to solubilize polar species that must be removed from the semiconductor substrate. The resultant etched substrates experience lower incidents of stiction relative to substrates etched using conventional wet etching techniques.

  • Publication number: 20060178006
    Abstract: Supercritical fluid-assisted deposition of materials on substrates, such as semiconductor substrates for integrated circuit device manufacture. The deposition is effected using a supercritical fluid-based composition containing the precursor(s) of the material to be deposited on the substrate surface. Such approach permits use of precursors that otherwise would be wholly unsuitable for deposition applications, as lacking requisite volatility and transport characteristics for vapor phase deposition processes.

    Abstract: A novel lead zirconium titanate (PZT) material having unique properties and application for PZT thin film capacitors and ferroelectric capacitor structures, e.g., FeRAMs, employing such thin film material. The PZT material is scalable, being dimensionally scalable, pulse length scalable and/or E-field scalable in character, and is useful for ferroelectric capacitors over a wide range of thicknesses, e.g., from about 20 nanometers to about 150 nanometers, and a range of lateral dimensions extending to as low as 0.15 ?m. Corresponding capacitor areas (i.e., lateral scaling) in a preferred embodiment are in the range of from about 104 to about 10?2 ?m2. The scalable PZT material of the invention may be formed by liquid delivery MOCVD, without PZT film modification techniques such as acceptor doping or use of film modifiers (e.g., Nb, Ta, La, Sr, Ca and the like).
