  • Patent number: 6714039
    Abstract: An active termination technique for reducing the propagation delay of a signal across a transmission line is presented. In accordance with a preferred embodiment of the invention, repeaters along a transmission line are paired with active termination circuits in very close proximity to the repeater in order to prevent signal reflections caused by the repeaters. The repeaters and associated active termination circuits are implemented with at least one PFET and at least one NFET, each having the same transistor gate lengths. The PFETs and the NFETs in the repeater and associated termination are ratioed to vary similarly over process/voltage/temperature variation.

  • Patent number: 6715105
    Abstract: A test method and apparatus allows simultaneous loading of multiple scan chains via a single common scan-in port (SDI) and a scan clock signal SCAN CLOCK. Data is scanned into one or more scanpaths from a scan data in (SDI) port under the control of a clock signal, either directly or indirectly through a linear feedback shift register (LFSR). Scan-out data output from the scanpaths may be read at the scan data out (SDO) port, either directly or indirectly through a signature register with optional masking functionality.

  • Patent number: 6713342
    Abstract: The present invention is directed to a method of forming an FeRAM integrated circuit, which includes forming a sidewall diffusion barrier prior to etching the bottom electrode diffusion barrier layer. The sidewall diffusion barrier layer is then etched prior to the bottom electrode diffusion barrier layer. In patterning an AlOx sidewall diffusion barrier layer prior to etching the underlying bottom electrode diffusion barrier layer, the etch chemistry comprises BCl3+Ar. The BCl3 is effective in etching the AlOx with a good selectivity to the underlying nitride hard mask on top of the capacitor stack (e.g., TiAlN) and nitride bottom electrode diffusion barrier (e.g., TiAlON with small oxygen content) between the neighboring capacitor stacks. The Ar may be added to the etch chemistry because the resulting surface (of a top portion of the hard mask and the bottom electrode diffusion barrier) is smoother.

  • Patent number: 6714883
    Abstract: A system and method for use in signal measurement systems that acquire and store signal data in accordance with a trigger specification. The present invention stores and displays operator-generated annotations with each trigger branch of a trigger specification. The annotations, referred to herein as trigger branch comments, can provide meaningful information about, for example, the trigger branch condition, occurrence specification or resulting action, as well as any other aspect of the trigger specification. The branch comments are stored with the associated trigger branch as part of the instrument configuration, and are automatically restored when the configuration data is loaded into the instrument, and printed with the associated trigger branch. The display of the trigger branch comments for each trigger branch may be controlled individually or collectively to enable the operator to configure the display of the trigger specification as needed.

  • Patent number: 6714565
    Abstract: A tunable optical resonator whose resonance frequency is determined by a light signal introduced into the resonator. The resonator includes an optical cavity having a first mirror and a second mirror. The first mirror and second mirror are supported relative to one another such that the distance between the first and second mirrors may be altered by applying a force to said second mirror thereby altering the resonance frequency of said cavity. The resonator includes a light input port for receiving a tuning light signal, and a light signal generator for generating the tuning light source. The tuning light signal is introduced into the optical cavity such that the tuning light signal is reflected between the first and second mirrors. In the absence of the tuning light signal, the resonator has a resonance characterized by a resonance response curve centered at &lgr;0.

  • Patent number: 6713955
    Abstract: An organic light emitting device having a process compatible current self-limiting (CSL) structure applied in the vicinity of an electrode of the device prevents the occurrence of high current flow in the vicinity of a short within the device. Should a short occur, the CSL structure becomes resistive, or non-conducting in the vicinity of the short, thus preventing the occurrence of “runaway” current in the vicinity of the short. By limiting the current flow between conductors in the device, the non-emissive areas of the device can be minimized, thus improving the overall reliability of the device.

  • Patent number: 6714036
    Abstract: Monitor circuitry for identifying an operational status of a device under test (DUT) includes a comparison circuit and a sense amplifier. The comparison circuit comprises a set of control transistors and a set of sense transistors. The control transistors include control input terminals for receiving reference signals to establish a testing condition with respect to a signal relationship between a first current flow and a second current flow. The sense transistors are operatively associated with the control transistors, such that biasing the sense input terminals of the sense transistors with sampled signals received from the DUT varies the signal relationship between the first current flow and the second current flow. The variation in the signal relationship is accelerated by the sense amplifier. The variation in the signal relationship is indicative of the operational status of the DUT at the sampling instance for acquiring the sampled signals.

  • Patent number: 6715112
    Abstract: A method and apparatus for displaying a waveform on an error performance analyzer are disclosed. A repeated base bit pattern is received. Then, at a first time and for each incremental time thereafter for a predetermined period of time, multivalued voltage, VM, is determined. The VM is determined by constructing a bit error rate (BER) curve at the each incremental time. Each BER-curve spans a range of voltages from a low slice voltage to a high slice voltage. A derivative of the BER-curve is taken and absolute value of the derivative is used to determine the VM which is the slice voltage where the absolute value of the derivative curve is greatest. The apparatus includes a processor and storage with instructions for the processor to perform these operations.

  • Patent number: 6709875
    Abstract: A ferroelectric device fabrication process is described in which ferroelectric device contaminant substances (e.g., Pb, Zr, Ti, and Ir) that are incompatible with standard CMOS fabrication processes are tightly controlled. In particular, specific etch chemistries have been developed to remove incompatible substances from the backside and edge surfaces of the substrate after a ferroelectric device has been formed. In addition, a sacrificial layer may be disposed over the bottom and edge surfaces (and, in some embodiments, the frontside edge exclusion zone surface) of the substrate to assist in the removal of difficult-to-etch contaminants (e.g., Ir). In this way, the ferroelectric device fabrication process may be integrated with a standard semiconductor fabrication process, whereby ferroelectric devices may be formed together with semiconductor integrated circuits without substantial risk of cross-contamination through shared equipment (e.g., steppers, metrology tools, and the like).

  • Patent number: 6710617
    Abstract: A method and circuit for controlling the slope of a transitioning signal on a transmission line of integrated circuit is achieved using stepwise pull-down impedance reduction/augmentation. Over a series of sequentially ordered steps, a predetermined decreasing (or increasing) impedance is connected between the transmission line and voltage source. Using certain predetermined impedance values in order, a linear slew rate on the output signal is achievable. Adjusting the time delay between each step allows the slope of the linear slew rate to be adjusted.
