  • Patent number: 9391020
    Abstract: A wavy line interconnect structure that accommodates small metal lines and enlarged diameter vias is disclosed. The enlarged diameter vias can be formed using a self-aligned dual damascene process without the need for a separate via lithography mask. The enlarged diameter vias make direct contact with at least three sides of the underlying metal lines, and can be aligned asymmetrically with respect to the metal line to increase the packing density of the metal pattern. The resulting vias have an aspect ratio that is relatively easy to fill, while the larger via footprint provides low via resistance. An interconnect structure having enlarged diameter vias can also feature air gaps to reduce the chance of dielectric breakdown. By allowing the via footprint to exceed the minimum size of the metal line width, a path is cleared for further process generations to continue shrinking metal lines to dimensions below 10 nm.

  • Patent number: 9377377
    Abstract: Methods and apparatus for measuring the modal bandwidth of a multimode optical fiber as a function of wavelength are disclosed. The methods include emitting polarized light from a single-mode fiber, frequency-modulating the single-mode polarized light, and then conditioning the frequency-modulated polarized light to excite multiple modes of the multimode optical fiber. The multimode light transmitted by the multimode optical fiber is detected and analyzed by a network analyzer to determine a bandwidth for at least three different wavelengths. A controller performs a fit to the measured bandwidths using a fitting equation to determine the modal bandwidth as a function of wavelength.

  • Patent number: 9325350
    Abstract: A communication device is configured to encode information bits using one or more forward error correction (FEC) codes and/or error correction codes (ECCs) to generate different codewords (e.g., codeword groups having different lengths, based on different code rates, etc.). The device generates a combined codeword using different sized codewords (e.g., long, medium, and short) by filling fills long codewords completely if possible, then filling medium codewords completely if possible with the remaining message bits (if any), and filling short codewords completely if possible plus another additional short codeword with the remaining message bits (if any). If the total number of short (or medium and short) codeword parity bits is greater than or equal to the number of medium (or long) codeword parity bits, then the device increments the number of medium (or long) codewords by one and setting the number of short (or medium and short) codewords to zero.

  • Publication number: 20160101924
    Abstract: A soft-sided insulated container assembly has a generally box-shaped form like a school lunch box, having a main body and a lid. The lid is formed of one of the largest panels of the box-structure, and is joined to the main body of the box by a hinge that lets the lid lie flat next to the main body when the box is open. The inside face of the lid then defines a work surface on which to place objects such as foodstuffs and beverages. The work surface may be formed in a substantially rigid molded stiffener member, and may be divided into sub-regions with raised retainers to discourage sliding of objects where not precisely level. The container assembly may include a rigid internal liner with which the lid may mate zipperlessly. The mating portion of the lid may be formed in the same rigid member as the work surface.

  • Patent number: 9255228
    Abstract: The present invention concerns a method of providing advisory controls for a desalter system. The method allows a user to continuously monitor performance of the desalter system, to continuously monitor position of the emulsion band (or rag layer), to control the emulsion band using demulsifiers, and to recommend to users how to maintain optimal pressure drop at the mix valve of the desalter system. This is achieved by using a first principles based model combined with an ultra-sound sensor. The ultra-sound sensor measures the position, quality and size of the emulsion band. The first principles based model takes into account the geometry of the desalter system, physical properties of the crude oil and water, as well as the operating conditions. Thus, the method provides users with sensing of an emulsion layer through ultrasound measurements and also gives recommendations on appropriate corrective actions to be initiated during upsets.

  • Publication number: 20160028496
    Abstract: A communication device (e.g., a cable modem (CM)) includes a digital to analog converter (DAC) and a power amplifier (PA) that generate a signal to be transmitting via a communication interface to another communication device (e.g., cable modem termination system (CMTS)). The CM includes diagnostic analyzer that samples the signal based on a fullband sample capture corresponding to a full bandwidth and/or a subset (e.g., narrowband) sample capture to generate a fullband and/or subset signal capture (e.g., of an upstream (US) communication channel between the CM and the CMTS). The diagnostic analyzer can be configured to generate sample captures of the signal based on any desired parameter(s), condition(s), and/or trigger(s). The CM then transmits the signal to the CMTS and the fullband and/or subset signal capture to the CMTS and/or a proactive network maintenance (PNM) communication device to determine at least one characteristic associated with performance of the US communication channel.

  • Publication number: 20150360846
    Abstract: A soft sided insulated container assembly includes a first portion having an insulated, soft sided external wall structure, and a second portion that defined a lid co-operable with the first portion. The lid includes an auxiliary access opening and closure member that are smaller than the main opening, and that can be operated one-handed. A rigid work surface is provided, typically immediately adjacent to the secondary closure member, the work surface providing a place for holding or mixing a drink or for preparing a snack. In some embodiments the work surface may be movable relative to the container, whether slidable in a co-planar or parallel planar manner in translation, or folding as in a foldable shelf. The entire container assembly may be foldable or collapsible to a storage condition, and the rigid member, whether fixed or movable, does not impede that folding or collapsing.

  • Patent number: 9214429
    Abstract: Ultra-low-k dielectric materials used as inter-layer dielectrics in high-performance integrated circuits are prone to be structurally unstable. The Young's modulus of such materials is decreased, resulting in porosity, poor film strength, cracking, and voids. An alternative dual damascene interconnect structure incorporates deep air gaps into a high modulus dielectric material to maintain structural stability while reducing capacitance between adjacent nanowires. Incorporation of a deep air gap having k=1.0 compensates for the use of a higher modulus film having a dielectric constant greater than the typical ultra-low-k (ULK) dielectric value of about 2.2. The higher modulus film containing the deep air gap is used as an insulator and a means of reducing fringe capacitance between adjacent metal lines. The dielectric layer between two adjacent metal lines thus forms a ULK/high-modulus dielectric bi-layer.

  • Publication number: 20150311113
    Abstract: An integrated circuit includes a substrate with an interlevel dielectric layer positioned above the substrate. First trenches having a first depth are formed in the interlevel dielectric layer and a metal material fills the first trenches to form first interconnection lines. Second trenches having a second depth are also formed in the interlevel dielectric layer and filled with a metal material to form second interconnection lines. The first and second interconnection lines have a substantially equal pitch, which in a preferred implementation is a sub-lithographic pitch, and different resistivities due to the difference in trench depth. The first and second trenches are formed with an etching process through a hard mask having corresponding first and second openings of different depths. A sidewall image transfer process is used to define sub-lithographic structures for forming the first and second openings in the hard mask.
