  • Publication number: 20170153870
    Abstract: A server, method, and non-transitory computer readable medium for ranking of a plurality of data sources are provided. The server includes a network interface, a memory storage unit and a processor. The method involves sending a test message, monitoring an external network for a response to the test message, determining whether a service level is satisfied and adjusting the rank of the data source. The non-transitory computer readable medium is encoded with codes to direct a processor to carry out the method.

  • Publication number: 20170154073
    Abstract: A system, method, and non-transitory computer readable medium for retrieving data in response to an input query is provided. The system includes a first data server configured to generate a query based on the input query and a second data server configured to generate a another query based on the input query. The system also includes a master server in communication with the data servers. The method involves generating queries based on the input query and sending the queries to data sources. The method also involves determining if data records represent the same external entity and combining data records to store. The non-transitory computer readable medium is encoded with codes to direct a processor to carry out the method.

  • Patent number: 9575963
    Abstract: A method, system, and computer program product provide a conversation agent to process natural language queries expressed by a user and perform commands according to the derived intention of the user. A natural language processing (NLP) engine derives intent using conditional random fields to identify a domain and at least one task embodied in the query. The NLP may further identify one or more subdomains, and one or more entities related to the identified command. A template system creates a data structure for information relevant to the derived intent and passes a template to a services manager for interfacing with one or more services capable of accomplishing the task. A dialog manager may elicit more entities from the user if required by the services manager and otherwise engage in conversation with the user. In one embodiment, the conversational agent allows a user to engage in multiple conversations simultaneously.

  • Patent number: 9570345
    Abstract: Resistance increase in Cobalt interconnects due to nitridation occurring during removal of surface oxide from Cobalt interconnects and deposition of Nitrogen-containing film on Cobalt interconnects is solved by a Hydrogen thermal anneal or plasma treatment.

  • Publication number: 20150220511
    Abstract: Provided is a system, method and computer-readable medium for generating data that may be used to train models for a natural language processing application. A system architect creates a plurality of sentence patterns that include entity variables and initiates sentence generation. Each entity is associated with one or more entity data sources. A language generator accepts the sentence patterns as inputs, and references the various entity sources to create a plurality of generated sentences. The generated sentences may be associated with a particular class and therefore used to train one or more statistical classification models and entity extraction models for associated models. The sentence generated process may be initiated and controlled using a user interface displayable on a computing device, the user interface in communication with the language generator module.

  • Publication number: 20150039292
    Abstract: A method and system are provided for processing natural language user queries for commanding a user interface to perform functions. Individual user queries are classified in accordance with the types of functions and a plurality of user queries may be related to define a particular command. To assist with classification, a query type for each user query is determined where the query type is one of a functional query requesting a particular new command to perform a particular type of function, an entity query relating to an entity associated with the particular new command having the particular type of function and a clarification query responding to a clarification question posed to clarify a prior user query having the particular type of function. Functional queries may be processed using a plurality of natural language processing techniques and scores from each technique combined to determine which type of function is commanded.

  • Patent number: 8350253
    Abstract: An integrated circuit (“IC”) fabricated on a semiconductor substrate has an active gate structure formed over a channel region in the semiconductor substrate. A dummy gate structure is formed on a dielectric isolation structure. The dummy gate structure and the active gate structure have the same width. A sidewall spacer on the dummy gate structure overlies a semiconductor portion between a strain-inducing insert and the dielectric isolation structure.

  • Patent number: 8329568
    Abstract: In one embodiment of the present invention, a field effect transistor device is provided. The field effect transistor device comprises an active area, including a first semiconductor material of a first conductivity type. A channel region is included within the active area. A gate region overlays the channel region, and the first source/drain region and the second source/drain region are embedded in the active area and spaced from each other by the channel region. The first source/drain region and the second source/drain region each include a second semiconductor material of a second conductivity type opposite of the first conductivity type. A well-tap region is embedded in the active area and spaced from the first source/drain region by the channel region and the second source/drain region. The well-tap region includes the second semiconductor material of the first conductivity type. The first source/drain region and the second source/drain region and the well-tap region are epitaxial deposits.

  • Patent number: 8302064
    Abstract: Device features, such as gate lengths and channel widths, are selectively altered by first identifying those devices within a semiconductor die that exhibit physical attributes, e.g., leakage current and threshold voltage magnitude, that are different than previously verified by a design/simulation tool used to design the devices. The identified, non-conforming devices are then further identified by the amount of deviation from the original design goal that is exhibited by each non-conforming device. The non-conforming devices are then mathematically categorized into bins, where each bin is tagged with a magnitude of deviation from a design goal. The mask layers defining the features of the non-conforming devices are then selectively modified by an amount that is commensurate with the tagged deviation. The selectively modified mask layers are then used to generate a new semiconductor die that exhibits improved performance.

  • Patent number: 8299564
    Abstract: Formation of transistors, such as, e.g., PMOS transistors, with diffusion regions having different depths for equalization of performance among transistors of an integrated circuit is described. Shallow-trench isolation structures are formed in a substrate formed at least in part of silicon for providing the transistors with at least substantially equivalent channel widths and lengths. A series of masks and etches is performed to form first recesses and second recesses defined in the silicon having different depths and respectively associated with first and second transistors. The second recesses are deeper than the first recesses. A silicon germanium film is formed in the first recesses and the second recesses. The silicon germanium film in the second recesses is thicker than the silicon germanium film in the first recesses, in order to increase performance of the second transistor so it is closer to the performance of the first transistor.

  • Patent number: 7793238
    Abstract: Various approaches for improving an integrated circuit layout. In one approach, a tree-type hierarchical layout representation of the circuit design is traversed. At each block visited during the traversing, a process determines whether there exists an improvement opportunity for each cell associated with the block. In response to determining that an improvement opportunity exists for a cell of a first block of the plurality of blocks, the process determines whether a modification to the cell satisfies one or more rules for every other block of the block type of the first block in the hierarchical representation. If the rules are satisfied, the modification is stored. Otherwise, the modification is discarded.
