  • Patent number: 7718500
    Abstract: A structure and method for forming raised source/drain structures in a NFET device and embedded SiGe source/drains in a PFET device. We provide a NFET gate structure over a NFET region in a substrate and PFET gate structure over a PFET region. We provide NFET SDE regions adjacent to the NFET gate and provide PFET SDE regions adjacent to the PFET gate. We form recesses in the PFET region in the substrate adjacent to the PFET second spacers. We form a PFET embedded source/drain stressor in the recesses. We form a NFET S/D epitaxial Si layer over the NFET SDE regions and a PFET S/D epitaxial Si layer over PFET embedded source/drain stressor. The epitaxial Si layer over PFET embedded source/drain stressor is consumed in a subsequent salicide step to form a stable and low resistivity silicide over the PFET embedded source/drain stressor.

  • Patent number: 7659174
    Abstract: A structure and method of fabrication of a semiconductor device having a stress relief layer under a stress layer in one region of a substrate. In a first example, a stress relief layer is formed over a first region of the substrate (e.g., PFET region) and not over a second region (e.g., NFET region). A stress layer is over the stress relief layer in the first region and over the devices and substrate/silicide in the second region. The NFET transistor performance is enhanced due to the overall tensile stress in the NFET channel while the degradation in the PFET transistor performance is reduced/eliminated due to the inclusion of the stress relief layer. In a second example embodiment, the stress relief layer is formed over the second region, but not the first region and the stress of the stress layer is reversed.

  • Publication number: 20090282090
    Abstract: A method and system for migrating source data from one or more databases to a destination database, wherein the destination database is selected based on power consumption of the destination database. A data migration server determines which destination database should be selected by selecting a number of candidates and comparing the power consumed, the available space and the maximum monthly power consumption limit. A user intervention policy is created to evaluate which data should be moved to a destination database. A “payback period” is calculated to determine the amount of time that will elapse before savings are realized.

  • Publication number: 20090282044
    Abstract: A method and system for provisioning data that has been collected and stored in a source database. The source database is a database that consumes a large amount of power and drains the company's database resources. The method and system determine which data should be provisioned and sent to a target server, the target server being more energy efficient than the source database and less exhausting of company resources. Various factors, such as the amount of data being requested and the frequency of change of the requested data, determine whether a transfer of data from the source database to the more energy efficient target database should be performed.

  • Publication number: 20090281847
    Abstract: A method and system for migrating source data from a source database to a destination database based on energy efficiency and conservation. A migration server evaluates the source data for usage and requirements and defines data usage and requirement tags for the source data. The source data is disaggregated into one or more source data sets based on the data usage and requirement tags. The migration server then identifies candidate destinations for the source data, wherein each candidate destination has stored data identified with usage and requirement tags. The data migration server compares the first usage and requirement tags of the source data with the second usage and requirement tags of the stored data and identifies an optimal destination database based on the comparing step. The data migration server migrates the source data to the optimal destination database.

  • Publication number: 20090030994
    Abstract: A method of generating a fingerprint of a bit sequence includes determining a relative occurrence frequency of each bit combination of a set of bit combinations in the bit sequence, wherein the set of bit combinations comprises all possible non-redundant sub-sequences of bits having at least one bit and at most a preset maximal number of bits. The method further includes determining for each bit combination of the set of bit combinations a difference value between the relative occurrence frequency of the bit combination and a random occurrence frequency, the random occurrence frequency relating to the expected random occurrence of the bit combination in the bit sequence. Moreover, the method includes allocating a set of bins, each bin of the set of bins being associated with a predetermined interval of difference values, each bin further relating to a bin value.

  • Publication number: 20090020851
    Abstract: A method of fabricating an heterojunction bipolar transistor (HBT) structure in a bipolar complementary metal-oxide-semiconductor (BiCMOS) process selectively thickens an oxide layer overlying a base region in areas that are not covered by a temporary emitter and spacers such that the temporary emitter can be removed and the base-emitter junction can be exposed without also completely removing the oxide overlying the areas of the base region that are not covered by the temporary emitter or spacers. As a result, a photomask is not required to remove the temporary emitter and to expose the base-emitter junction.

  • Publication number: 20080313604
    Abstract: A system and method for declaring variables during coding of a software program. The method includes, for each variable type, defining a unique string representing a variable declaration instruction and adapting a coding module wherein, when a string representing a variable declaration instruction is typed adjacent to a new variable name, the coding module automatically generates code for the corresponding variable declaration statement for a new variable having the new variable name and the specified variable type. The method further includes defining a reserved variable declaration area in the software program and placing any code generated by the coding module for the variable declaration statement into the reserved variable declaration area. Each unique string representing a variable declaration instruction may be a prefix or suffix that may be typed adjacent to the new variable name.

  • Patent number: 7405131
    Abstract: The example embodiments disclose devices and methods to prevent silicide strapping of the Source/Drain to Body in semiconductor devices with S/D stressor. We provide isolation regions in the substrate and a gate structure over the substrate. We form recesses in the substrate adjacent to the gate structure with disposable spacers and adjacent to the isolation regions. We provide stressor regions filling the recesses. The stress region can have a pit adjacent the isolation regions. We form stressor spacers at least partially in the pit on the sidewalls of the stressor regions. We form silicide regions over the stressor regions. The spacer on the stressor regions sidewalls inhibit the formation of silicide at the stressor region edge during the silicide process, thus preventing silicide strapping of the Source/Drain to Body.

  • Patent number: 7404726
    Abstract: An apparatus is disclosed that surrounds a connector and places it within the printer body in such away as to allow for the connector to float against the intrusion of a sliding can mounted with electronics and to set up and enable the printer. The problem solved is that of the blind-mating connectors within a printer system for which an industry standard connector set for flex cable must be used. It is advantageous to allow a connector that is attached to a flex cable to float even though the floating feature has not been considered in the original design and the connector was not made for the amount of misalignment present in a blind-mate connection. In addition, by a single-rib design, an extra degree of freedom for rotational around Y-axis is provided to the floating connector to further guide the lead-in of the contacting face of the mating connector.
