  • Publication number: 20090300073
    Abstract: A system and method to ensure a low-latency read of log records from a Database Management System (“DBMS”) in asynchronous log-based database replication capture from a blocking log read Application Programming Interface (“API”). The system may include a replication server with a log read module to initialize a log read thread. The reading module of the log read thread may read a predefined number of DBMS log records. A log flush module of the log flush thread may be executed by the log read thread and waits for a read complete notification. The update module, in response to a log flush thread time out, may also generate a plurality of loggable transactions such that a number of log records in an internal API log satisfies a DMBS threshold and unblocks the DBMS API. Therefore, the latency time may be constant, low, and predictable ensuring an accurate replication capture.

  • Patent number: 7557031
    Abstract: A method for manufacturing an LCOS device includes forming an interlayer dielectric layer overlying a surface region of a substrate. The interlayer dielectric layer is patterned to form a plurality of recessed regions. Each of the recessed regions corresponds to a pixel element for a LCOS device and is isolated by a portion of dielectric material defining a border for each of the recessed regions. An aluminum material or aluminum alloy material is deposited within each of the recessed regions. A photomask is formed overlying the aluminum material and patterned to expose the recessed regions while protecting the border regions. Exposed regions of the aluminum material is removed while the border regions with the photomask is protected. The method continues the removing until the aluminum material has been removed to a vicinity of an upper region of the border regions. The patterned photomask is stripped to expose protruding aluminum material.

  • Patent number: 7377101
    Abstract: The invention provides a NOx adsorber aftertreatment system for internal combustion engines which utilizes a plasma fuel converter operatively coupled to at least one NOx adsorber to aid in the regeneration of the NOx adsorber. Fuel and engine exhaust is injected into a plasma fuel converter upstream of a NOx absorber producing reductant such as H2, and CO, which are inlet into the NOx absorber. Reductants such as H2 and CO acting along and together help to efficiently regenerate the NOx Adsorber which in turn releases exhausts products such as CO2 and N2. Using the reductants generated by the plasma fuel converter NOx adsorbers, catalytic soot filter, and the like can be regenerated at exhaust temperatures less than 250° C. The plasma fuel converter, NOx adsorber regenerating aftertreatment system of the present invention may be used with any suitable control system.

  • Patent number: 7276435
    Abstract: An integrated circuit has metal bumps on the top surface that create a potentially destructive stress on the underlying layers when the metal bumps are formed. Ensuring a minimum metal concentration in the underlying metal interconnect layers has been implemented to reduce the destructive effect. The minimum metal concentration is highest in the corners, next along the border not in the corner, and next is the interior. The regions in an interconnect layer generally under the metal bump require more concentration than adjacent regions not under a bump. Lesser concentration is required for the metal interconnect layers that are further from the surface of the integrated circuit. The desired metal concentration is achieved by first trying a relatively simple solution. If that is not effective, different approaches are attempted until the minimum concentration is reached or until the last approach has been attempted.

  • Patent number: 7200670
    Abstract: The payloads of IP packets are checked to actually determine if a packet contains MPEG-2 video rather than using predefined streams or priority levels that are assumed to contain such information as is done in the prior art. More specifically, the “sync” bytes of the MPEG-2 stream are searched for within the IP packet payload, and when a pattern indicative of the sync bytes is found the sync bytes are identified and the packet is determined to contain MPEG-2 video. The sync byte was defined in MPEG-2 for over-the-air broadcasting in order that a television receiver be able to synchronize the MPEG-2 transport stream packets. Note that the MPEG-2 video, e.g., the MPEG-2 transport stream packets, may or may not be incorporated within real time protocol (RTP) packets before being incorporated into the IP packets.

  • Patent number: 7176574
    Abstract: A conductive line varies in thickness to assist in overcoming RC delays and noise coupling. By varying line thickness, variation in conductor width is avoided if necessary to maintain a specified minimum pitch between conductors while maintaining predetermined desired RC parameters and noise characteristics of the conductive line. Conductor depth variation is achieved by etching a dielectric layer to different thicknesses. A subsequent conductive fill over the dielectric layer and in the differing thicknesses results in a conductive line that varies in thickness. Different conductive line thicknesses available at a particular metal level can additionally be used for semiconductor structures other than a signal or a power supply conductive line, such as a contact, a via or an electrode of a device. The thickness analysis required to determine how interconnect thickness is varied in order to meet a desired design criteria may be automated and provided as a CAD tool.

  • Patent number: RE39126
    Abstract: A method for forming conductive plugs within an insulation material is described. The inventive process results in a plug of a material such as tungsten which is more even with the insulation layer surface than conventional plug formation techniques. Conventional processes result in recessed plugs which are not easily or reliably coupled with subsequent layers of sputtered aluminum or other conductors. The inventive process uses a two-step chemical mechanical planarization technique. An insulation layer with contact holes is formed, and a metal layer is formed thereover. A polishing pad rotates against the wafer surface while a slurry selective to the metal removes the metal overlying the wafer surface, and also recesses the metal within the contact holes due to the chemical nature and fibrous element of the polishing pad. A second CMP step uses a slurry having an acid or base selective to the insulation material to remove the insulator from around the metal.
