20090074141 | Automated selection of x-ray reflectometry measurement locations - A computer-implemented method for inspection of a sample includes defining a plurality of locations on a surface of the sample, irradiating the surface at each of the locations with a beam of X-rays, and measuring an angular distribution of the X-rays that are emitted from the surface responsively to the beam, so as to produce a respective plurality of X-ray spectra. The X-ray spectra are analyzed to produce respective figures-of-merit indicative of a measurement quality of the X-ray spectra at the respective locations. One or more locations are selected out of the plurality of locations responsively to the figures-of-merit, and a property of the sample is estimated using the X-ray spectra measured at the selected locations. | 03-19-2009 |
20130089178 | X-ray inspection of bumps on a semiconductor substrate - A method for inspection includes irradiating, with a focused beam, a feature formed on a semiconductor wafer, the feature including a volume containing a first material and a cap made of a second material, different from the first material, that is formed over the volume. One or more detectors positioned at different angles relative to the feature are used to detect X-ray fluorescent photons that are emitted by the first material in response to the irradiating beam and pass through the cap before striking the detectors. Signals output by the one or more detectors at the different angles in response to the detected photons are processed in order to assess a quality of the cap. | 04-11-2013 |
20140286473 | ESTIMATION OF XRF INTENSITY FROM AN ARRAY OF MICRO-BUMPS - A method for inspection includes capturing an optical image of one or more features on a surface of a sample and irradiating an area of the sample containing at least one of the features with an X-ray beam. An intensity of X-ray fluorescence emitted from the sample in response to the irradiating X-ray beam is measured. The optical image is processed so as to extract geometrical parameters of the at least one of the features and to compute a correction factor responsively to the geometrical parameters. The correction factor is applied to the measured intensity in order to derive a property of the at least one of the features. | 09-25-2014 |
20150330921 | METHOD FOR ACCURATELY DETERMINING THE THICKNESS AND/OR ELEMENTAL COMPOSITION OF SMALL FEATURES ON THIN-SUBSTRATES USING MICRO-XRF - A method for X-ray Fluorescence (XRF) analysis includes directing an X-ray beam onto a sample and measuring an XRF signal excited from the sample, in a reference measurement in which the sample includes one or more first layers formed on a substrate, and in a target measurement after one or more second layers are formed on the substrate in addition to the first layers, so as to produce a reference XRF spectrum and a target XRF spectrum, respectively. A contribution of the first layers to the target XRF spectrum is reduced using the reference XRF spectrum. A parameter of at least one of the second layers is estimated using the target XRF spectrum in which the contribution of the first layers has been reduced. | 11-19-2015 |

20090067573 | X-ray measurement of properties of nano-particles - A method for analyzing a sample includes directing one or more beams of X-rays to impinge on an area of a surface of the sample on which a layer of nano-particles of a selected element has been formed. Secondary X-ray radiation from the area is detected responsively to the one or more beams. A distribution of the nano-particles on the surface is characterized based on the detected radiation. | 03-12-2009 |

20150350221 | SHARED DATA WITHIN A FAMILY - One or more user accounts can be linked together to form a group of linked user accounts. A shared calendar can be assigned to a group of linked user accounts. A shared calendar can be a unique calendar assigned to the group of linked user accounts that can be accessed by each member of the group of linked user accounts to schedule appointments, reminders, etc. A shared task list can be assigned to a group of linked user accounts and accessed by each member of the group of linked user accounts. Members of the group of linked user accounts can add tasks to the shared task list that can then be viewed by the other members of the group of linked user accounts. This can allow a family to add tasks to the shared task list that can then be completed by other members of the family. | 12-03-2015 |

20080216654 | Fluted filter media - Fluted filter media includes filter material having a plurality of flutes formed therein having alternating ends of adjacent flutes closed to force fluid through filter material. A first embodiment of the filter media includes tapered flutes which have the open ends of the flutes larger in cross-section than the closed flutes, wherein the upstream open flutes converge toward the downstream end and the upstream closed end flutes diverge toward the downstream end. A second embodiment includes filter media which is asymmetric formed with dissimilar upstream and downstream flute cross-sections with larger flute openings to the upstream side of the filter. A third embodiment includes filter media with an upstream edge crushed to improve flow at the upstream edge. A fourth embodiment includes filter media with the upstream sealing material recessed from the upstream edge for reducing effects from blockages at the upstream edge of the filter. | 09-11-2008 |

20100030974 | SYSTEM AND METHOD FOR FETCHING INFORMATION TO A CACHE MODULE USING A WRITE BACK ALLOCATE ALGORITHM - A write back allocate system that includes: (i) a store request circuit; (ii) a processor, adapted to generate a store request that comprises an information unit and an information unit address; and (iii) a cache module, connected to the store request circuit and to a high level memory unit. A single cache module line includes multiple segments, each segment is adapted to store a single information unit. A content of a cache module line is retrieved from the high level memory unit by generating a fetch burst that includes multiple segment fetch operations. The store request circuit includes a snooper and a controller. The snooper detects a portion of an address of a cache segment of a cache line that is being fetched during a fetch burst. The controller is adapted to request from the cache module to receive the information unit before a completion of the fetch burst if the portion of the address of the cache segment matches a corresponding portion of the information unit address. | 02-04-2010 |
