  • Publication number: 20080155465
    Abstract: Techniques are described for identifying items that have recently undergone an interest burst. Items that have recently undergone an interest burst are identified by comparing how many interest-actions have been performed on the items during a current time window against how many interest-actions have been performed on the items historically. Various tests are performed to rule out candidates that are not likely to be of interest to other users. In addition, various spam detection techniques are described for reducing the possibility that the items that are listed as interest burst items are listed because of spam.

  • Patent number: 7371629
    Abstract: A method is provided for improving Idsat in NMOS and PMOS transistors. A silicon nitride etch stop layer is deposited by a PECVD technique on STI and silicide regions and on sidewall spacers during a MOSFET manufacturing scheme. A dielectric layer is formed on the nitride and then contact holes are fabricated through the dielectric layer and nitride layer to silicide regions and are filled with a metal. For NMOS transistors, silane and NH3 flow rates and a 400° C. temperature are critical in improving NMOS short channel Idsat. Hydrogen content in the nitride is increased by higher NH3 and SiH4 flow rates but does not significantly degrade HCE and Vt. With PMOS transistors, deposition temperature is increased to 550° C. to reduce hydrogen content and improve HCE and Vt stability.

  • Publication number: 20070174247
    Abstract: A set of general criteria have been defined to improve the efficacy of a tagging system, and have been applied to present collaborative tag suggestions to a user. The collaborative tag suggestions are based on a goodness measure for tags derived from collective user authorities to combat spam. The goodness measure is iteratively adjusted by a reward-penalty algorithm during tag selection. The collaborative tag suggestions can also incorporate other sources of tags, e.g., content-based auto-generated tags.
