  • Patent number: 6510081
    Abstract: By reducing the size of the blocks or pages that are contained in a FLASH EEPROM array that must be erased in a write or erase operation, the size of register needed is reduced, making it easier for the processor to handle smaller blocks of information, reducing the size and complexity of the microprocessor, and increasing the endurance of the FLASH EEPROM allowing it to be used in place of the state of the art EEPROM. Replacing mask ROM by flash EEPROM allows full testing of the code storage area as well as allowing customers to use that space for testing in their manufacturing procedures. The code used for testing can then be cleared and reprogrammed with the final code storage before final shipment.

  • Patent number: 6504015
    Abstract: Group II metal MOCVD precursor compositions are described having utility for MOCVD of the corresponding Group II metal-containing films. The complexes are Group II metal &bgr;-diketonate adducts of the formula M(&bgr;-diketonate)2(L)4 wherein M is the Group II metal and L is tetrahydrofuran. Such source reagent complexes of barium and strontium are usefully employed in the formation of barium strontium titanate and other Group II thin films on substrates for microelectronic device applications, such as integrated circuits, ferroelectric memories, switches, radiation detectors, thin-film capacitors, microelectromechanical structures (MEMS) and holographic storage media.

  • Patent number: 6500489
    Abstract: Chemical vapor deposition is used to form a film of Bi oxide, Sr oxide, and Ta oxide on a heated substrate by decomposing the precursors of these oxides at the surface of the substrate. The precursor of Bi oxide is a Bi complex which includes at least one alkoxide group and is decomposed and deposited at a temperature lower than 450° C. The film of Bi, Sr, and Ta oxides obtained by low-temperature CVD is predominantly non-ferroelectric, but can be converted into a ferroelectric film by a subsequent heating process.

  • Patent number: 6495011
    Abstract: An apparatus and method for the indirect determination of concentrations of additives in metal plating electrolyte solutions, particularly organic additives in Cu-metalization baths for semiconductor manufacturing. The apparatus features a reference electrode housed in an electrically isolated chamber and continuously immersed in the base metal plating solution (without the additive to be measured). An additive concentration determination method comprises electroplating a test electrode at a constant or known current in a mixing chamber wherein the base metal plating solution is mixed with small volumes of the sample and various calibration solutions containing the additive to be measured. Plating potentials between the electrodes are measured and plotted for each of the solution mixtures, and data are extrapolated to determine the concentration of the additive in the sample.

  • Patent number: 6471750
    Abstract: A gas containment assembly including a containment enclosure defining an enclosed interior volume, with an exhaust inlet and an exhaust outlet for flow of exhaust gas into the enclosed interior volume through the exhaust inlet and flow from the containment enclosure through the exhaust outlet. A gas supply vessel and/or gas flow circuitry is provided in the interior volume of the containment enclosure. A back-migration scrubber unit overlies and is sealed to the exhaust inlet so that back-flow migration of gas from the gas supply vessel and/or gas flow circuitry in the interior volume of the containment enclosure is sorptively taken up by sorbent material in the scrubber unit and prevented from passing into an ambient environment in which said gas containment assembly is deployed. This arrangement permits significant reduction in the flow rate of exhaust gas through the gas containment enclosure without compromising the safety of the gas containment assembly.

  • Patent number: 6466488
    Abstract: A logic level detection circuit that includes a sense amplifier and a consumption equilibration circuit that is topologically distinct from the sense amplifier and that reduces and/or substantially eliminates data dependent electrical consumption by having a data dependent electrical consumption that compensates the data dependent electrical consumption of the sense amplifier. The sense amplifier may be implemented as a current-sensing sense amplifier, and the consumption equilibration circuit may be implemented as a selectively enabled current source that is responsive to a signal generated by the current-sensing sense amplifier. The consumption equilibration circuit may be implemented with a small number of transistors and in a small chip area compared to the number of transistors and chip area used for implementing the sense amplifier.
