Appl. No.:

11/146514

Inventors:

David Kuan-Yu Liu - Fremont CA, US
Jonathan Cheang-Whang Chang - Mountain View CA, US

Assignee:

Xilinx, Inc. - San Jose CA

International Classification:

H01L 21/336

US Classification:

438197, 257E21327, 257E21623

Abstract:

Polysilicon or other material is directionally trimmed using two layers of photoresist and a photoresist etching process, such as ashing. A first layer of photoresist is patterned on a wafer. Portions of the first patterned photoresist are covered with a second layer of photoresist. The photoresist is trimmed to reduce the size of the exposed portions of the first patterned photoresist without reducing the size of the covered portions of the first patterned photoresist. The second layer of photoresist is removed. The selectively etched patterned first layer of photoresist is used as a process mask to define a structure in the underlying material. In a particular embodiment, the second photoresist covers endcap portions of gate photoresist. Directional trimming reduces the width of a polysilicon gate structure (i. e. gate length) over an active area of an FET, without reducing the length of original first patterned photoresist.

International Classification:

H04L 12/28

US Classification:

37039532, 37039543

Abstract:

A method and device to process a packet received by a network device is described. The method may comprise analyzing the packet to identify at least one set of a plurality of sets, mapping the at least one set to at least one functional unit, and performing functionality associated with the at least one functional unit. Analyzing the packet to identify at least one of a plurality of sets may comprise determining when the packet includes at least one set identifier, and identifying the at least one set based on the at least one set identifier. A set status identifier may be defined for each set, the set status identifier indicating when set identifiers associated with a corresponding set are detected in the packet. The device may be a router, switch or any other device that processes digital data e. g. , packet data including packets headers, payload or the like.

Abstract:

Methods and apparatuses to dynamically customize a listing to track a selected type of responses to be generated from a presentation of the customized listing, where the selection of the type of responses is based at least in part on one or more characteristics of the request for the listing. One embodiment includes receiving a request for a listing of an entity; determining a characteristic of the request; selecting a type of responses for the listing based on the determined characteristic; generating a version of the listing to track the type of responses that are responsive to a presentation of the listing; and providing the version of the listing in response to the request.

International Classification:

US Classification:

709204

Abstract:

Equivalent concepts expressed across multiple domains are matched and associated with a metapage generated by a social networking system. User preferences expressed on multiple domains, represented as pages in a social networking system, may be organized by concept and shared with advertisers, third-party developers, and other users using the metapages generated for the concepts. Aggregated social information may be presented to users viewing a page associated with a metapage. Information presented on external websites may be used to link pages across multiple domains with a metapage generated on the social networking system. Information on other external websites associated with the metapage may be presented as links on the pages associated with the metapage. Feedback from users may be used to include or exclude pages from being associated with a generated metapage. A best page for a concept embodied in multiple pages may be determined using a hierarchy of rules.
