  • Publication number: 20200118809
    Abstract: Methods are provided for conducting a deposition on a semiconductor substrate by selectively depositing a material on the substrate. The substrate has a plurality of substrate materials, each with a different nucleation delay corresponding to the material deposited thereon. Specifically, the nucleation delay associated with a first substrate material on which deposition is intended is less than the nucleation delay associated with a second substrate material on which deposition is not intended according to a nucleation delay differential, which degrades as deposition proceeds. A portion of the deposited material is etched to reestablish the nucleation delay differential between the first and the second substrate materials. The material is further selectively deposited on the substrate.

  • Publication number: 20200013201
    Abstract: This disclosure relates generally to image processing, and more particularly to method and system for image reconstruction using deep dictionary learning (DDL). The system collects the degraded image as test image and processes the test image to extract sparse features from the test image, at different levels, using dictionaries. The extracted sparse features and data from the dictionaries are used by the system to reconstruct the HR image corresponding to the test image.

  • Publication number: 20190182202
    Abstract: A multi-chassis link aggregation (MC-LAG) system includes one or more dual homed nodes coupled to a pair of switches (MC pair) and one or more single homed nodes coupled to a single one of the MC pair of switches. The MC pair of switches advertises a virtual IP address for the dual homed nodes such that traffic may be received at either switch in the MC pair for the dual homed nodes. For a single homed node, a dedicated IP address is advertised associated with a switch in the MC pair locally connected to the single homed node. Traffic destined to the single homed node is thus transmitted to the switch in the MC pair locally connected to the single homed node.

  • Publication number: 20180357100
    Abstract: A method in a database system is disclosed. The method comprises generating a task template object from a platform entity with polymorphic lookup capability that can map to multiple tenant domains wherein the task template object contains one or more task completion storage records for storing task-specific information, converting the task template object into a work-type object by storing task-specific information in the one or more task completion storage records wherein the work-type object comprises a work-type object identifier (ID), a first record for recording the database ID of one or more work order objects mapped to the work-type object, and a first task completion storage record for storing a first type of task-specific information. The method further comprises generating a work order object for a task and providing the work order object with access to the task-specific information by linking the work-type object to the work order object.

  • Publication number: 20100187172
    Abstract: Fabrication of self-aligned closed packed titania nanotube arrays in excess of 10 ?m in length and aspect ratio ?10,000 by potentiostatic anodization of titanium is disclosed. Conditions for achieving complete anodization and absolute tailorability of Ti foil samples resulting in a self-standing mechanically robust titania membrane in excess of 1000 ?m are also disclosed.

  • Publication number: 20100139747
    Abstract: A method of making semiconducting oxide nanowire arrays on such as rutile is disclosed wherein a substrate is heated in the presence of a reaction mixture of non-polar solvent, semi-conductor metal oxide precursor source and strong acid to produce a nanowire array of a semiconducting oxide on the substrate. Dye sensitized solar cells that employ these nanowire arrays also are disclosed.
