  • Patent number: 7060586
    Abstract: PrCaMnO (PCMO) thin films with predetermined memory-resistance characteristics and associated formation processes have been provided. In one aspect the method comprises: forming a Pr3+1?xCa2+xMnO thin film composition, where 0.1<x<0.6; in response to the selection of x, varying the ratio of Mn and O ions as follows: O2?(3±20%); Mn3+((1?x)±20%); and, Mn4+(x±20%). When the PCMO thin film has a Pr3+0.70Ca2+0.30Mn3+0.78Mn4+0.22O2?2.96 composition, the ratio of Mn and O ions varies as follows: O2?(2.96); Mn3+((1?x)+8%); and, Mn4+(x?8%). In another aspect, the method creates a density in the PCMO film, responsive to the crystallographic orientation. For example, if the PCMO film has a (110) orientation, a density is created in the range of 5 to 6.76 Mn atoms per 100 ?2 in a plane perpendicular to the (110) orientation.

  • Publication number: 20060068099
    Abstract: The present invention discloses a method to achieve grading PCMO thin film for use in RRAM memory devices since the contents of Ca, Mn and Pr in a PCMO film can have great influence on its switching property. By choosing precursors for Pr, Ca and Mn having different deposition rate behaviors with respect to deposition temperature or vaporizer temperature, PCMO thin film of grading Pr, Ca or Mn distribution can be achieved by varying that process condition during deposition. The present invention can also be broadly applied to the fabrication of any multicomponent grading thin film process by varying any of the deposition parameters after preparing multiple precursors to have different deposition rate behaviors with respect to that particular process parameter. The present invention starts with a proper selection of precursors in which the selected precursors have different deposition rates with respect to at least one deposition condition such as deposition temperature or vaporizer temperature.

    Abstract: A sense amplifier has a charge sharing compensator to eliminate wake-up delays in an output signal. The charge sharing compensator comprises a capacitor or a charge storing means to compensate for charges in a charge sharing path that has two different voltage potentials. The compensator also has a transistor for selecting a signal path to transfer charges from the capacitor, eliminating charge sharing in the bit line path of the sense amplifier. Another aspect of the present invention is a method for resolving charge sharing problems that comprises steps of choosing a proper value for a compensating capacitor, choosing a control signal for a charge sharing compensation means, and clamping down an input terminal of the sense amplifier.
