  • Patent number: 7424687
    Abstract: A method and apparatus are provided for receiving a list of design memories, wherein each type of design memory in the list has a name and at least one instance. A pre-placement model is associated with each named memory type in the list. The design memories in the list are mapped to an integrated circuit layout pattern, wherein at least one memory type comprises first and second instances that are mapped differently from one another. After mapping, at least one of the first and second instances is renamed to have a different name than the other. A post-placement model is then associated with each named memory type in the list, including a separate model for each renamed design memory.

  • Publication number: 20080216048
    Abstract: A graphical profile map for integrated circuits on a substrate. The graphical profile map includes a depiction of die placement boundaries and shot placement boundaries for the integrated circuits on the substrate. Also included are integrated circuit property information contours, where the contours are not limited to either of the die placement boundaries or the shot placement boundaries. In this manner, three key pieces of information for the integrated circuits are presented, including integrated circuit property information, die placement, and shot placement. Because these three pieces of information are presented in a graphical form, it is much easier to interpret the information. For example, it is much easier to determine which shot and die placements have properties that are at risk, and which shot and die placements have adequate property profiles.

  • Patent number: 7420229
    Abstract: A test vehicle for evaluating a manufacturing process for integrated circuits that uses a more space efficient layout of library driving cells arranged to produce circuits that exercise many interconnections that may be designed at the minimum design parameters of a manufacturing process. The cells can be configured to operate as ring oscillators increasing the effective circuit frequency of the test module allowing higher frequency circuit testing, and shortening the time it takes to perform life cycle testing. Visibly marking cells, combined with electrically isolating error prone circuit segments makes, identifying defects much more efficient. The accessibility of many testing methods allows quick location of root cause failures, which allows improvements to be made to the manufacturing process.

  • Patent number: 7418550
    Abstract: Methods and structure for improved import of RAID level 6 logical volumes into subsystems devoid of RAID level 6 hardware support. When a RAID level 6 logical volume is exported from a first storage subsystem and imported into a second storage subsystem devoid of RAID level 6 hardware support, features and aspects hereof first migrate the logical volume for use as a logical volume with a different RAID level supported by the second storage subsystem. The migration may be, for example, to a RAID level 5 logical volume performed by movement of data blocks to form new stripes and re-generation of associated parity blocks or by simpler re-mapping of existing blocks of the RAID level 6 volume to use only blocks and parity needed for RAID level 5 management. Further features and aspects allow migration to any other RAID management level supported by the second storage subsystem.

  • Patent number: 7415543
    Abstract: A boot menu is provided for manual setting of serial port parameters. A serial console mode menu allows an operator to set serial port parameter values. After the user selects the serial port parameters, when the controller continues with the boot process, the serial port is initialized with the newly selected parameters. A mechanism is also provided for manual setting of serial port parameters through an administrative management window at the host. In addition, an adaptive baud rate negotiation mechanism using the Universal Asynchronous Receiver Transmitter (UART) registers in the serial port is provided. The adaptive baud rate negotiation is based on the return characters received from a break character from the serial console. The mechanism uses a look-up table for the baud rate versus the bit pattern that is received. The mechanism then sets the baud rate based on the look-up table values.

Each shell surrounds the critical location and each preceding shell. An ordering of the shells and at least one of a timing constraint and an area constraint are selected for each shell. Each shell is placed and routed in the order selected according to the timing constraint and area constraint.

  • Patent number: 7413996
    Abstract: A method of forming a high k gate insulation layer in an integrated circuit on a substrate. A high k layer is deposited onto the substrate, and patterned with a mask to define the high k gate insulation layer and exposed portions of the high k layer. The exposed portions of the high k layer are subjected to an ion implanted species that causes lattice damage to the exposed portions of the high k layer. The lattice damaged exposed portions of the high k layer are etched to leave the high k gate insulation layer.

  • Patent number: 7413984
    Abstract: Embodiments of the invention include a method for forming a copper interconnect having a bi-layer copper barrier layer. The method comprises the steps of providing a substrate with a low-K dielectric insulating layer and an opening in the insulating layer. A first barrier layer of tantalum/tantalum nitride is formed on the insulating layer and in the opening. A second barrier layer consisting of a material selected from the group of palladium, chromium, tantalum, magnesium, and molybdenum is formed on the first barrier layer. A copper seed layer is formed on the second barrier layer and implanted with barrier ions and a bulk copper layer is formed on the seed layer. The substrate is annealed and subject to further processing which can include planarization.

  • Patent number: 7414721
    Abstract: An in-line, in-process or in-situ and non-destructive metrology system, apparatus and method provides composition, quality and/or thickness measurement of a thin film or multi-layer thin film formed on a substrate in a thin film processing system. Particularly, the subject invention provides a spectroscopic ellipsometer performing spectroscopic ellipsometry while the wafer is in a thin film processing system. In one form, the spectroscopic ellipsometer is associated with a wet bench system portion of the thin film processing system. The spectroscopic ellipsometer obtains characteristic data regarding the formed thin film to calculate penetration depth (Dp) for a thin film formed on the substrate. Particularly, the ellipsometer obtains an extinction coefficient (k) which is used to calculate penetration depth (Dp). Penetration depth (Dp), being a unique function of the extinction coefficient (k) provides the information for the composition, quality and/or thickness monitoring of the thin film.
