  • Patent number: 8716104
    Abstract: A method of fabricating an isolation structure of a semiconductor device includes the following steps. Firstly, a substrate including a first surface and a second surface is provided. At least one trench is formed in the first surface of the substrate. The trench has a sidewall and a bottom surface. Then, a first chemical vapor deposition process is performed to form a first isolation layer on the first surface of the substrate and the sidewall and the bottom surface of the trench. Then, an anisotropic surface treatment process is performed, so that a surface of the first isolation layer has differential surface chemical properties. Afterwards, a second chemical vapor deposition process is performed to form a second isolation layer on the first isolation layer with a surface having differential surface chemical properties.

  • Publication number: 20140108428
    Abstract: An online social networking system can be used to rank social network objects of various different object types, each according to its type. The objects may comprise types such as users, communities, blogs, blog entries, events, forums, forum topics, postings, photographs, and/or images. The product comprises code for carrying out a method that begins with receiving ranking data about social network objects that comprises data about events performed on the social network. For each social network object, a ranking function is applied to ranking data about the social network object based on its type. In addition, the recency of an event on the social network related to the social network object is evaluated, in order to calculate the score for the social network object. A relative ranking for each of the plurality of social network objects based on its score is determined, and the score and relative ranking of each of the social network objects stored.

    Abstract: The present disclosure is directed toward solutions, transparent films prepared from aromatic copolyamides, and a display element, an optical element or an illumination element using the solutions and/or the films. The copolyamides, which contain pendant carboxylic groups are solution cast into films using cresol, xylene, N,N-dimethylacetamide (DMAc), N-methyl-2-pyrrolidinone (NMP), dimethylsulfoxide (DMSO), or butyl cellosolve or other solvents or mixed solvent which has more than two solvents. When the films are thermally cured at temperatures near the copolymer glass transition temperature, after curing, the polymer films display transmittances >80% from 400 to 750 nm, have coefficients of thermal expansion of less than 20 ppm, and are solvent resistant.
