  • Patent number: 9310418
    Abstract: Methods, apparatus, and computer program products for evaluating current transients measured during an electrical stress evaluation of a dielectric layer in a semiconductor device. Measured current transients are fit to an equation representing a time dependence for stress induced leakage currents. The measured current transients are corrected based upon stress currents computed from the equation to define corrected current transients.

  • Patent number: 9310424
    Abstract: A mechanism is provided for determining a modeled age of a mufti-core processor. For each core in a set of cores in the multi-core processor, a determination is made of a temperature, a voltage, and a frequency at regular intervals for a set of degradations and a set of voltage domains, thereby forming the modeled age of the multi-core processor. A determination is made as to whether the modeled age of the multi-core processor is greater than an end-of-life value. Responsive to the modeled age of the multi-core processor being greater than an end-of-life value, an indication is sent that the multi-core processor requires replacement.

  • Patent number: 8713490
    Abstract: A mechanism is provided for mitigating aging of a set of components in the data processing system. A modeled age of a component in the set of components is identified. A desired aging requirement for the component is identified and a determination is made as to whether the modeled age of the component is greater than the desired age of the component. Responsive to the modeled age of the component being greater than the desired age of the component, a policy is implemented to mitigate the aging of the component.

  • Patent number: 8587383
    Abstract: A method establishes an initial voltage in a ring oscillator and a logic circuit of an integrated circuit device. Following this, the method enables the operating state of the ring oscillator. After enabling the operating state of the ring oscillator, the method steps up to a stressing voltage in the ring oscillator. The initial voltage is approximately one-half the stressing voltage. The stressing voltage creates operating-level stress within the ring oscillator. The method measures the operating-level frequency within the ring oscillator using an oscilloscope (after stepping up to the stressing voltage).

  • Patent number: 6770501
    Abstract: Semiconductor structures are provided with on-board deuterium reservoirs or with deuterium ingress paths which allow for diffusion of deuterium to semiconductor device regions for passivation purposes. The on-board deuterium reservoirs are in the form of plugs which extend through an insulating layer and a deuterium barrier layer to the semiconductor substrate, and are preferably positioned in contact with a shallow trench oxide which will allow diffusion of deuterium to the semiconductor devices. The deuterium ingress paths extend through thin film layers from the top or through the silicon substrate.

  • Patent number: 6307250
    Abstract: An electronic switch circuit switches out bad decoupling capacitors on a high speed integrated circuit chip. The circuit comprises a control device that operates in the subthreshold or off device state to detect leakage in a decoupling capacitor. This control device operates in a low impedance state if the capacitor is good and in a high impedance sate if the capacitor is bad. A feedback circuit is connected from an internal node of the capacitor to a gate of the control device so that once a state of the capacitor is detected it can be stored on the gate of the control device. A single external signal source shared by a group of capacitors activates the control device to detect leakage in the capacitor. The circuit operates to switch out capacitors that fail during normal operation.

    Abstract: A non-volatile random access memory (NVRAM) structure comprising an injector element in a single crystal silicon substrate; an insulator layer over the substrate; a silicon-on-insulator (SOI) layer over the insulator layer; and a sensing element in the SOI layer overlying the injector element. The NVRAM structure may further comprise a gate above the SOI layer, a floating gate in the insulator layer, or both.

  • Patent number: 5982225
    Abstract: A circuit actively monitors and measures the amount of MOS device degradation due to, for example, the hot electron effect, and makes compensatory adjustments to device voltage levels or clock speed to maintain desired levels of functionality and performance. Monitoring can be done separately for NFET and PFET devices to selectively adjust for different degradation rates between the two. In operation, the monitor circuit compares the performance of a stressed device to a reference device, that is, an unstressed device which has not been degraded by the hot-electron effect. The monitor circuit outputs a signal indicating the amount of device degradation. This signal is used to adjust the supply voltage to that device or to the chip or otherwise compensate for the degradation. The monitor circuit can be formed on-chip or off-chip.
