  • Patent number: 7005879
    Abstract: Noise reduction for application of structural test patterns to a Device Under Test (DUT) is accomplished with a capacitor “booster” bypass network on the probe card in which the capacitors are charged to a much higher voltage Vboost than the DUT power supply voltage VDD. Charging the capacitors to a voltage N×VDD allows the buster network to store N times the charge of a conventionally configured capacitance network, and effectively provides N times the capacitance of the original network in the same physical space.

  • Patent number: 7003537
    Abstract: To implement an operation in Jacobian with improved computation complexity, the sum is computed of a divisor D1=g.c.d. (a1(x),y?b1(x)) and a divisor D2=g.c.d. (a2(x),y?b2(x)) on Jacobian of a hyperelliptic curve y2+y=f(x) defined over GF(2n) by: storing a1(x), a2(x), b1(x) and b2(x); and calculating q(x)=s1(b1(x)+b2(x)) mod a2(x) by using s1(x) in s1(x)a1(x)+s2(x)a2(x)=1 in case of GCD(a1(x),a2(x))=1 where GCD denotes a greatest common polynomial. Thus, a new function q(x) is provided so as to reduce the entire computational complexity and the hardware size. Moreover, in the case of D1=D2, a1(x) and b1(x) is stored; and q(x)=Q(b12(x)+f(x) mod a12(x), a1(x)) where Q(A,B) is a quotient of A/B is calculated.

  • Patent number: 7001844
    Abstract: Stress level of a nitride film is adjusted as a function of two or more of the following: identity of a starting material precursor used to make the nitride film; identity of a nitrogen-containing precursor with which is treated the starting material precursor; ratio of the starting material precursor to the nitrogen-containing precursor; a set of CVD conditions under which the film is grown; and/or a thickness to which the film is grown. A rapid thermal chemical vapor deposition (RTCVD) film produced by reacting a compound containing silicon, nitrogen and carbon (such as bis-tertiary butyl amino silane (BTBAS)) with NH3 can provide advantageous properties, such as high stress and excellent performance in an etch-stop application. An ammonia-treated BTBAS film is particularly excellent in providing a high-stress property, and further having maintainability of that high-stress property over repeated annealing.

  • Patent number: 6996543
    Abstract: In order to verify the authenticity of manufactured goods, a smart tag is attached to the goods containing encrypted authentication information, such as a serial number, a description of the good's physical appearance or chemical decomposition, its color, or digital images of the good etc. The encryption procedure comprises public/private key encryption with zero-knowledge protocols. Zero knowledge protocols allow a smart tag to be authenticatable and yet be duplication resistant by allowing the verifying agent to convince him/herself that the smart tag is authentic without revealing its authentication information. The verification procedure can be done using a reader at a point of sale (POS) machine equipped with the appropriate public key and zero-knowledge protocols to decrypt the authentication information. A printed version of the serial number or other authentication information may be placed on the goods in human readable form to quickly verify the information electronically read from the smart tag.

  • Patent number: 6992696
    Abstract: Resolution of an image capture system is measured by imaging a test target having a progression of feature sizes and pitch in respective sub-fields thereof. The image captured by the imaging system is then inspected to determine a sub-field image which does not include aliasing in the form of a Moire' pattern. Inclusion of reference numerals corresponding to the sub-field image feature size and pitch allows direct reading of the resolution of the imaging system. Such a system enables fast and accurate determination of the resolution and alignment of an imaging system using an inexpensively produced test target together with an arbitrary image viewing program.

  • Patent number: 6989997
    Abstract: Buck converters having a resonant inductor Lr, resonant capacitor Cr, and synchronous switch Q3 that together provide reduced switching loss and soft switching. In operation, the resonant inductor Lr is charged during a time period A. Then, Lr is freewheeling and provides current to an output inductor Lo. Then, Q3 is turned OFF, and energy from the resonant inductor Lr charges the resonant capacitor Cr. Finally, energy from the resonant capacitor Cr is provided to the output inductor and load. The output power can be adjusted by phase control of the operation of switch Q3. In alternative embodiments, the circuit has a pair of coupled inductors L1 L2 or an isolation transformer 40. The coupled inductors have a polarity selected so that the output voltage is reduced, thereby allowing top switch Q1 to have a greater duty cycle. These circuits feature no body diode loss in the switch Q3.

  • Patent number: 6989922
    Abstract: Mechanical control and actuation of an adaptive optical element provides highly stable and repeatable correction of the shape of an optical element to an accuracy of a small fraction of a very short wavelength of light, responsive to a metrology source and sensor arrangement. Actuators in the form of individual set-screws or other actuators capable of axially positioning a shaft are driven by a robotic screw driver with four degrees of freedom or one or more linear actuators to exert force on the mirror. Positive or negative force may be used for outward and/or inward deflection of the mirror. When a desired force is developed on the mirror through a mechanical linkage, the linkage may be clamped by a passive clamp which may be released by an actuator such that the adjustment is maintained while the linear actuator and the clamp actuator are turned off; yielding a highly stable adjustment while effectively removing sources of actuator drift, noise, vibration and heating which may adversely affect stability.

  • Patent number: 6982625
    Abstract: An electronic event recorder for attachment to a vehicle is provided which can broadcast encrypted signature and data, thereby leaving behind an electronic version of a “fingerprint” in the event of an accident or traffic violation. The fingerprint, captured by an external data acquisition system or another vehicle so equipped, provides a history of events related to the vehicle. The event recorder is preferably integrated on a smart card and housed in a tamper proof casing. In a first mode of operation, monitoring stations along the roadways periodically send an interrogation signal, such as when radar detects that the vehicle is speeding. Upon receiving the interrogation signal the smart card transmits the vehicle's signature information to the monitoring station where it is time and date stamped along with the speed of the vehicle.
