  • Patent number: 7067048
    Abstract: A method and apparatus which uses a plating electrode in an electrolyte bath. The plating electrode works to purify an electrolyte polishing solution during the electro-polishing process. Preferably, the plating electrode is employed in a closed loop feedback system. The plating electrode may be powered by a power supply which is controlled by a controller. A sensor may be connected to the controller and the sensor may be configured to sense a characteristic (for example, but not limited to: resistance, conductance or optical transmission, absorption of light, etc.) of the electrolyte bath, which tends to indicate the level of saturation. Preferably, the plating electrode is easily replaceable.

  • Patent number: 7067882
    Abstract: The present invention is an apparatus and system for providing a high quality spiral inductor in an integrated circuit environment. A layer of inductor may be placed within the metal layers along with negative capacitance generation circuitry of the present invention to compensate for the capacitance associated with the metal layers adjacent to the inductor to provide a higher quality factor for the inductor. Advantageously, circuitry of the present invention may be employed within an integrated circuit without modifying the layer structure of the integrated circuit. Additionally, values of the components of the circuitry may be selectively and independently chosen to synthesize a variable range of negative capacitance.

  • Patent number: 7069523
    Abstract: A tool for designing integrated circuits that optimizes the placement and timing of memory blocks within the circuit. Given a manufactured slice that has a number of blocks already diffused and logically integrated, the memory generation tool herein automatically considers the available diffused memory and the gate array of the slices to configure and optimize them into a customer's requirements for memory. The memory generation tool has a memory manager, a memory resource database, a memory resource selector, and a memory composer. Together these all interact to generate memories from the available memories within the memory resource database. The memory composer actually generates the RTL logic shells for the memories, and outputs the memory designs in Verilog, VHDL, or other tool synthesis language. Once a memory is created, it is tested.

  • Patent number: 7067223
    Abstract: A phase shift mask having transmission properties that are dependent at least in part on an intensity of an incident light beam. The phase shift mask has a mask substrate that is substantially transparent to the incident light beam. A first phase shift layer is disposed on the mask substrate. The first phase shift layer has a refractive index that is nonlinear with the intensity of the incident light beam. The refractive index of the first phase shift layer changes with the intensity of the incident light beam on the phase shift mask. By using a first phase shift layer on the phase shift mask that has a refractive index that is non linear with the intensity of the incident light beam, properties of a light beam transmitted through the first phase shift layer, such as interference patterns in the transmitted light beam, can be adjusted by adjusting the intensity of the incident light beam.

  • Patent number: 7069535
    Abstract: A method of silicon design reproducibility enhancement using priority assignments prior to performing a conventional optical proximity correction process on a device. The present invention seeks to improve the manufacturability of VLSI devices. The present invention inserts a priority assignment step prior to the conventional OPC correction process in order to assert better control over transistor parameters. The priority assignment step sorts the layout by degree of importance to the cell/device performance. Areas designated as critical are given higher priority values while areas designated as non-critical are given lower priority values. The present invention imposes more precise accuracy requirements to high priority value areas and less precise accuracy requirements to low priority value areas. As a result, the present invention imposes the tightest accuracy requirements to critical areas of device performance, rather than attempting to achieve overall accuracy during the OPC correction process.

  • Patent number: 7062731
    Abstract: A method of noise analysis and correction of noise violations for an integrated circuit design includes steps of receiving as input a standard parasitic exchange file for an integrated circuit design and parsing the standard parasitic exchange file to generate a resistance graph. A representation of the resistance graph is generated to determine noise critical nets. A list is generated of only noise critical nets from the representation of the resistance graph. A net is selected from the list of only noise critical nets, and a value of total crosstalk noise in the selected net from all aggressor nets relative to the selected net is calculated. The value of total crosstalk noise in the selected net is generated as output for correcting a noise violation.

  • Patent number: 7061267
    Abstract: A logical gate and a comparator are used to detect page boundaries in a data stream. A current address and a predetermined page size, that is an integer power of 2, are compared using a Boolean logic gate such as AND or XOR to detect a page boundary in a data stream. The output from the Boolean logic gate is compared to a predetermined value to cause a signal to be generated, indicating the end of the page.

  • Patent number: 7062590
    Abstract: Methods and associated structure for providing broadcast of PCI bus transactions using device ID messaging (DIM) features of the PCI bus specifications. A vendor defined class of messages are defined using device ID messaging to provide broadcast of messages across PCI bus bridge devices to multiple PCI bus segments. One aspect hereof provides for using implicitly addressed device ID messaging such that bridge devices, compatible with the vendor defined message classes, will forward the message upstream and downstream. Another feature provides for use of explicitly addressed device ID messaging to effectuate the desired broadcast. Another aspect hereof provides for translation of a received DIM formatted message with broadcast information and applying the broadcast information to a second bus segment as a standard PCI broadcast transaction.

  • Patent number: 7062415
    Abstract: A method for determining outlier data points in. A subset of dataset patterns is selected from a set of mathematical dataset patterns, and the subset of dataset patterns is combined into a composite dataset. The composite dataset is compared to the dataset, and a degree of correlation between the composite dataset and the dataset is determined. Data points within the composite dataset are selectively weighted to improve the degree of correlation, and the steps described above are selectively iteratively repeated until the degree of correlation is at least a desired value. Residuals for the data points within the composite dataset are selectively determined. At least one of the weighted data points within the composite dataset that are weighted within a first specified range, and data points within the composite dataset that have a residual within a second specified range, are selectively output as outlier data points.

  • Patent number: 7061822
    Abstract: A clock generating circuit for a pseudo dual port memory incorporates feedback, delays, and latches to ensure that the write (read) operation clock pulse is sufficiently spaced in time from the read (write) operation clock. The clock generating circuit receives an external clock, a read enable signal, a write enable signal, and a reset signal as inputs. Advantages include minimization of the clock cycle time and operation unaffected by the duty ratio of an external clock. Delay circuitry may be added such that the generated clock signal has sufficient fan out and is sufficiently stable.
