  • LEADFRAME HAVING DIE ATTACH PAD WITH DELAMINATION AND CRACK-ARRESTING FEATURES
    Publication number: 20090152691
    Abstract: One aspect of the invention pertains to a semiconductor package having a die and a die attach pad with a plurality of spaced apart pedestals supported by a web. A die is mounted on the die attach pad such that the die is supported by at least a plurality of the pedestals. Selected edge regions of the die are arranged to overlie recessed regions of the die attach pad between adjacent pedestals. The die is electrically connected to at least some of the contact leads. An adhesive is arranged to secure the die to the die attach pad, with the thickness of the adhesive between the web of the die attach pad and the die being greater than the thickness of the adhesive between the die and the top surfaces of the pedestals that support the die. The die attach pad may have rounded peripheral corners between adjacent edge surfaces of the die attach pad.

  • ROUNDED DIE CONFIGURATION FOR STRESS MINIMIZATION AND ENHANCED THERMO-MECHANICAL RELIABILITY
    Publication number: 20090152683
    Abstract: One aspect of the invention pertains to a semiconductor die with rounded sidewall junction edge corners. Such rounding reduces stress accumulations at those corners. In other embodiments of the invention, the sharpness of other corners and edges in the die are reduced. For example, reducing the sharpness of the bottom edge corners formed by the intersection of a sidewall and the back surface of a die can further diminish stress accumulations. One embodiment pertains to a wafer carried on a wafer support, where the wafer includes a multiplicity of such dice. Another embodiment involves a semiconductor package containing such dice. Methods of fabricating the dice are also described.

  • Low Voltage Charge Pump with Regulation
    Publication number: 20090153230
    Abstract: Techniques of providing a low output voltage, high current capability charge pump are given. The charge pump has multiple capacitors along with switching circuitry. In an initialization phase, the first plate of each of the capacitors is connected to receive a regulator voltage and the second plate of each capacitor is connected to ground. In a transfer phase, the capacitors are connected in series, where, for each capacitor after the first, the second plate is connected to the first plate of the preceding capacitor in the series. The output voltage of the pump is from the first plate of the last capacitor in the series. Regulation circuitry generates the regulator voltage from a reference voltage to have a value responsive to the output voltage level of the pump.

  • USE OF EXTERNAL SERVICES WITH CLUSTERS
    Publication number: 20090158292
    Abstract: A method, apparatus, and system are directed toward managing a system that includes a cluster and an external resource. The external resource may be part of a second cluster that is collocated on the same hardware platforms as the cluster. A proxy resource is used to enforce a dependency relationship between a native resource of the cluster and an external resource, such that a dependency with the proxy resource serves to enforce a dependency with the external resource. The cluster framework may maintain states of the proxy resource, including an offline state, an online-standby state, and an online state. The online-standby indicates that the proxy has been started, but it has not determined that the associated external resource is enabled. The proxy may determine whether the external resource is enabled or disabled and, in response, notify the cluster framework.
