  • Patent number: 7550980
    Abstract: Apparatus within power sourcing equipment and a method for determining whether a load within a powered device coupled to the power sourcing equipment via a cable is within an acceptable resistance range. If the load is within the acceptable resistance range, a voltage source is coupled to the load. In one embodiment one recharge interval is employed during which a capacitor is charged based, at least in part, on the voltage drop across the load and one discharge interval is employed during which a capacitor is discharged based, at least in part, on the voltage drop across the load. In a second embodiment, first and second recharge and discharge intervals are employed and prior to initiation of the recharge and discharge intervals, settling time periods are provided.

  • Patent number: 7550852
    Abstract: An integrated circuit chip which has a plurality of pads and non-reflowable contact members to be connected by reflow attachment to external parts. Each of these contact members has a height-to-diameter ratio and uniform diameter favorable for absorbing strain under thermo-mechanical stress. The members have a solderable surface on each end and a layer of reflowable material on each end. Each member is solder-attached at one end to a chip contact pad, while the other end of each member is operable for reflow attachment to external parts.

  • Patent number: 7551114
    Abstract: A stage of a pipelined ADC used as a sub-ADC in a time-interleaved ADC is operated using a first set of clock signals, with a next stage being operated using a second set of clock signals. The first set and second set of clock signals are designed to cause the start of hold phases of the stage to occur earlier than the sample phases of the next stage. In an embodiment, the start of the hold phases is coincident with the end of an immediately preceding sample phase of the stage. As a result, more time is provided for the output of an amplifier used in the stage to settle to a final value, thus permitting use of a low speed amplifier and reduction in power consumption in the interleaved ADC. In an embodiment, the stage corresponds to an earliest stage in the pipelined sub-ADC.

    Abstract: One embodiment provides a system for protecting at least one component in an integrated circuit (IC). The system includes a disconnect element that is electrically connected in series between an input terminal of the IC and the at least one component. The disconnect element is configured to have a first state to electrically connect the terminal to the at least one component and a second state corresponding to a high impedance condition that electrically isolates the terminal relative to the at least one component. A control system is configured to cause the disconnect element to transition from the first state to the second state in response to a rate of change of an input signal at the terminal exceeding a predetermined rate of change.

  • Patent number: 7550314
    Abstract: A patterned plasma treatment may be provided on the chip and/or the substrate to enhance the distribution of underfill material between the chip and the substrate. The underfill material is typically dispensed after the chip is electrically connected to the substrate. The chip may be electrically connected to the substrate by an array of solder bumps, as one example. The underfill material is draw into a gap between the chip and the substrate by a capillary action. The patterned plasma-treated area formed on the chip and/or on the substrate may cause greater capillary force on the underfill material, as compared to non-plasma-treated areas. Such patterned plasma-treatment area may be designed and laid out to provide for more or better control of the underfill distribution between the chip and substrate while forming a chip package.

  • Patent number: 7547596
    Abstract: A method of manufacturing a semiconductor device includes forming transistors including gate electrodes and source/drain regions over a substrate. A protective layer is placed over the source/drain regions and the gate electrodes. A portion of the protective layer is removed to expose a portion of the gate electrodes. The exposed portions of the gate electrodes are amorphized, and remaining portions of the protective layer located over the source/drain regions are removed. A stress memorization layer is formed over the gate electrodes, and the substrate is annealed in the presence of the stress memorization layer to at least reduce an amorphous content of the gate electrodes. The stress memorization layer is removed subsequent to the annealing.
