Patent number: 9865490Abstract: The invention broadly relates to cyclic olefin polymer bonding compositions and release compositions, to be used independently or together, that enable thin wafer handling during microelectronics manufacturing, especially during a full-wafer mechanical debonding process. The release compositions comprise compositions made from siloxane polymers and copolymers blended in a polar solvent, and that are stable at room temperature for longer than one month. The cyclic olefin polymer bonding compositions provide high thermal stability, can be bonded to fully-treated carrier wafers, can be mechanically or laser debonded after high-temperature heat treatment, and are easily removed with an industrially-acceptable solvent. Wafers bonded according to the invention demonstrate lower overall post-grind stack TTV compared to other commercial bonding materials and can survive 200° C. PECVD processing.Type: GrantFiled: October 24, 2016Date of Patent: January 9, 2018Assignee: Brewer Science Inc.Inventors: Dongshun Bai, Gu Xu, Debbie Blumenshine, Baron Huang, Andrew Wong

Patent number: 9514221Abstract: Systems, methods, and computer-readable storage media are provided for utilizing part-of-speech (POS) tagging of both the words included in a search query and the words included in potential search result documents to improve query alteration accuracy and search result ranking. Upon receiving a search query, POS tags are assigned to the words comprising the query to create query word-tag pairs. The query word-tag pairs are utilized to reformulate the query and are compared with document word-tag pairs included in a plurality of potential search result documents to determine a degree of similarity. The degree of similarity is utilized as an input in scoring and/or ranking the relevance of the potential search result documents with respect to one another.Type: GrantFiled: March 14, 2013Date of Patent: December 6, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Kyrylo Tropin, Ka Cheung Sia, Gu Xu, Bhuvan Middha, Qi Yao, Sandeep Dey, Junbiao Tang

Patent number: 9286396Abstract: Various technologies described herein pertain to use of path-constrained random walks for query expansion and/or query document matching. Clickthrough data from search logs is represented as a labeled and directed graph. Path-constrained random walks are executed over the graph based upon an input query. The graph includes a first set of nodes that represent queries included in the clickthrough data from search logs, a second set of nodes that represent documents included in the clickthrough data from the search logs, a third set of nodes that represent words from the queries and the documents, and edges between nodes that represent relationships between queries, documents, and words. The path-constrained random walks include traversals over edges of the graph between nodes. Further, a score for a relationship between a target node and a source node representative of the input query is computed based at least in part upon the path-constrained random walks.Type: GrantFiled: July 26, 2013Date of Patent: March 15, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Jianfeng Gao, Gu Xu, Jinxi Xu

Patent number: 9195942Abstract: A method and system for identifying information about people is provided. The information system identifies groups of people that have relationships based on their relationships to documents or more generally to objects. The information system initially is provided with an indication of which people have which relationships to which documents. The information system then identifies clusters of people based on having a relationship to the same objects. The information system may also identify clusters of related objects associated with a cluster of people. When a user wants to identify information about a person, the user can provide the name of that person to the information system. The information system then can retrieve and display the names of the other people who are in the same cluster as the person.Type: GrantFiled: March 17, 2009Date of Patent: November 24, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Benyu Zhang, Wei-Ying Ma, Gu Xu, Hongbin Gao, Zheng Chen, Randy Hinrichs, Hua-Jun Zeng

Patent number: 8612367Abstract: Techniques are described for determining queries that are similar to rare queries. An n-gram space is defined to represent queries and a similarity function is defined to measure the similarities between queries. The similarity function is learned by leveraging training data derived from user behavior data and formalized as an optimization problem using a metric learning approach. Furthermore, the similarity function can be defined in the n-gram space, which is equivalent to a cosine similarity in a transformed n-gram space. Locality sensitive hashing can be exploited for efficient retrieval of similar queries from a large query repository. This technique can be used to enhance the accuracy of query similarity calculation for rare queries, facilitate the retrieval of similar queries and significantly improve search relevance.Type: GrantFiled: February 4, 2011Date of Patent: December 17, 2013Assignee: Microsoft CorporationInventors: Jingfang Xu, Gu Xu, Hang Li
