  • Patent number: 7371659
    Abstract: A method for forming a feature in a substrate, where residue within the feature can be easily removed. An upper sidewall portion of the feature is formed, where the upper sidewall portion forms a void in the substrate. The upper sidewall portion has an upper sidewall angle. A lower sidewall portion of the feature is formed, where the lower sidewall portion forms a void in the substrate. The lower sidewall portion has a lower sidewall angle. The upper sidewall angle of the upper sidewall portion is shallower than the lower sidewall angle of the lower sidewall portion. By forming the feature with a shallower sidewall angle at the top of the feature, any debris within the feature is more susceptible to rinsing, etching, or other cleaning procedures, and thus the feature is more easily cleaned than standard features having relatively steeper sidewalls.

  • Patent number: 7373622
    Abstract: An apparatus including a base layer of a platform application specific integrated circuit (ASIC), a mixed-signal function and a built-in self test (BIST) function. The base layer of the platform ASIC generally includes a plurality of pre-diffused regions disposed around a periphery of the platform ASIC. Each of the pre-diffused regions is generally configured to be metal-programmable. The mixed-signal function may include two or more sub-functions formed with a metal mask set placed over a first number of the plurality of pre-diffused regions. The BIST function may be formed with a metal mask set placed over a second number of the plurality of pre-diffused regions. The BIST function may be configured to test the mixed-signal function and present a digital signal indicating an operating condition of the mixed-signal function.

  • Patent number: 7373089
    Abstract: Methods and apparatus for providing improving optical signal transmission results over standard mode fiber using a combination of negative chirp, low extinction ratio, and self-phase modulation transmission techniques in combination are described. The use of pre-transmission signal distortion in combinations with one or more of the other transmission techniques is also described. Pre-transmission signal distortion may be introduced by controlling a modulator with a large symmetric AC signal which causes the modulator to operation in a non-linear region or, alternatively, by using a relatively small non-symmetric AC signal to drive the modulator. Use of the small non-symmetric signal has the advantage of reduced power requirements. The pre-transmission distortion acts to counter some of the distortion introduced by the transmission of the signal over an optic fiber.

  • Publication number: 20080109688
    Abstract: A built in self test circuit disposed within a memory matrix. Individual memory cells within the memory matrix are disposed into logical columns. The built in self test circuit has only one memory test controller, which is adapted to initiate test commands and receive test results. Transport controllers are uniquely paired with each one of the logical columns of memory cells. Each of the transport controllers is adapted to receive test commands from the memory test controller, test memory cells within the logical column as instructed by the test commands, receive test results from the logical column of memory cells, and provide the test results to the memory test controller. The transport controllers are also adapted to selectively operate in three different modes under control of the memory test controller.

  • Publication number: 20080102583
    Abstract: A transistor integration process provides a damascene method for the formation of gate electrodes and gate dielectric layers. An interlayer-dielectric film is deposited prior to the gate electrode formation to avoid the demanding gap fill requirements presented by adjacent gates. A trench is formed in the interlayer-dielectric film followed by the deposition of the gate material in the trench. This process avoids the potential for damage to high-k gate dielectric layers caused by high thermal cycles and also reduces or eliminates the problematic formation of voids in the dielectric layers filling the gaps between adjacent gates.

  • Patent number: 7365015
    Abstract: A method of forming a metal gate in a wafer. PolySi1-xGex and polysilicon are used to form a tapered groove. Gate oxide, PolySi1-xGex, and polysilicon is deposited on a wafer. A resist pattern is formed. A portion of the polysilicon, PolySi1-xGex, and gate oxide is removed to provide a tapered profile. The resist is removed; a dielectric liner is deposited, and then at least a portion of the dielectric liner is removed, thereby exposing the polysilicon and leaving the dielectric liner in contact with the polysilicon, PolyS1-xGex, and gate oxide. A dielectric is deposited, and a portion is removed thereby exposing the polysilicon. The polysilicon, PolySi1-xGex, and gate oxide is removed from inside the dielectric liner, thereby leaving a tapered gate groove. Metal is then deposited in the groove.

  • Patent number: 7366957
    Abstract: The present invention is a method and system for providing a complete validation of an initiator and target within bus architecture. A target's behavior may be controlled by an initiator. Control of the target may be through execution of initiator commands including vendor unique commands relating to desired characteristics for testing. The initiator's response to the target's behavior may be verified due to the handshaking communication protocol between a target and initiator. Additionally, by altering the behavior of the target to test initiator response, a target's behavior is also validated.
