  • Publication number: 20040031338
    Abstract: An apparatus and method for detecting in chamber wafer position and process status are disclosed. A chamber includes a processing pedestal and plurality of lift pins. Each lift pin has an associated load cell for measuring the load exerted by the wafer on the lift pins. Mispositioned wafers or broken wafers will result in load measurements outside of expected ranges. Position of the wafer may be determined from the load distribution sensed on the lift pins.

  • Publication number: 20030227624
    Abstract: An apparatus and method for detecting mispositioned wafers attributable to transfer shift of the wafer are disclosed. A calibration wafer has a target region comprising a pattern of optically distinguishable features from which is determined the position of the calibration wafer within the chamber subsequent to its transfer therein. Preferably, the features comprise a pattern of colors that can be detected by spectroscopy. A preferred form and manner of providing such color features is by way of dielectric thin film filters.

  • Patent number: 6538647
    Abstract: A power-saving data driver for stepwisely applying alternating driving voltages with a predetermined number of steps to a plurality of data lines in a liquid crystal display is disclosed. The data driver is comprised of a clocking means, a plurality of reference voltages, and a plurality of analog voltage driver. The clocking means is used for providing clock signals for stepwisely charging and discharging. The plurality of reference voltages work as steps of said stepwisely charging and discharging. The reference voltages are distributed between the system voltage and the ground. Each of the analog voltage driver corresponds to one of the data lines. A given pixel is stepwisely driven from a driving voltage of the last pixel as a beginning voltage to a driving voltage of the given pixel as a target voltage. The reference voltages between the beginning voltage and the target voltage are turned-on in order according to the clock signals generated by the clocking means.

  • Patent number: 6239080
    Abstract: A material having a superconducting transition temperature (Tc) of 126 K under ambient pressure has been identified. The superconducting material belongs to a Ba—Ca—Cu—O compound family where the cation ratio of Ba:Ca:Cu is 2:2.5+0.5:3.5±0.5. The superconducting material is produced from precursor oxides having nominal formula Ba2Can−1+xCuu/yOx wherein n=3 or 4 and x is 0.4 to 1.0 and y is 0 to 0.8 using high-pressure synthesis. Final synthesis temperature was maintained at less than 950° C. Formation of the superconducting material is sensitive to the state of the precursor oxides, the carbon content of the precursor, and the synthesis temperature, pressure and time.
