  • Publication number: 20210202300
    Abstract: In accordance with embodiments of the present disclosure, a method for fabricating a Metal-Oxide Semiconductor (MOS) device may include: depositing a silicon-nitride (SiN) layer above a substrate surface of a silicon wafer; etching one or more trenches on the silicon wafer; performing a high-temperature post-liner-anneal process on the silicon wafer to reduce stress from the etched SiN layer to the silicon wafer; and filling the one or more trenches with oxide isolation material. The high-temperature post-liner-anneal process may reduce the dependence of the saturation current of the MOS device on the channel width.

  • Patent number: 9652474
    Abstract: A method and a system provide regional content to users by associating data files with geographical properties and matching the geographical property of a data file with the geographical property of the user. The system extracts geographical information from a data file, and associates the data file with a source geographical property corresponding to the extracted geographical information according to a geographical information database. Upon obtaining a user geographical property of a user, the system provides the data file to the user if the source geographical property matches the user geographical property. The method and the system may be implemented using a geographical name lexicon or a geographical name suffix lexicon.

  • Patent number: 9141642
    Abstract: A method determines core geographical information in a document by computing a score for each geographical name found in the document. The computation of the score uses the appearance frequency of the respective geographical name and positional weights assigned to various types of appearance positions of the geographical name in the document. The system determines the core geographical information in the document based on the scores of the geographical names found in the document. The method may further compute aggregated scores of geographical regions related to the geographical names and determine the core geographical information using both the aggregated scores of geographical regions and the scores of individual geographical names to increase accuracy.
