  • Patent number: 10770413
    Abstract: A chip packaging structure and method, and an electronic device, are provided. The chip packaging structure includes a support, a chip, at least one conductor, and a package for plastic packaging the support, the chip and the conductor. The chip is arranged on an upper surface of the support, a chip pad is formed on the upper surface of the chip, and the chip pad is connected to an external pad of the support by a bonding wire. The conductor is connected to the external pad or a ground pad of the chip pad, and the shortest distance from the conductor to the upper surface of the package is less than the shortest distance from the bonding wire to the upper surface of the package, whereby chip failure caused by static electricity discharge is greatly reduced.

  • Patent number: 10654976
    Abstract: A method for producing a cross-linked siloxane network comprises the steps of: (a) providing a first part comprising (i) a first siloxane compound comprising at least one cyclic siloxane moiety and (ii) a second siloxane compound comprising a plurality of siloxane moieties, (b) providing a second part, the second part comprising a hydroxide salt, (c) combining the first part and the second part to produce a reaction mixture, (d) heating the reaction mixture to a temperature sufficient for the hydroxide salt to open the ring of the cyclic siloxane moiety, and (e) maintaining the reaction mixture at an elevated temperature so that at least a portion of the opened cyclic siloxane moieties react to produce a cross-linked siloxane network.

  • Publication number: 20200095397
    Abstract: An additive composition comprises one or more calcium cis-1,2-cyclohexanedicarboxylate salts. The calcium 1,2-cyclohexanedicarboxylate salts have a BET specific surface area of 20 m2/g or more. A method for producing a thermoplastic polymer composition entails mixing the additive composition with a thermoplastic polymer, melting the resulting admixture, and letting the admixture solidify to produce a polymer composition.

  • Patent number: 9228069
    Abstract: A process of forming a nanopatterned substrate is provided. The process comprising the steps of first preparing a giant surfactant comprising a cage-like molecular nanoparticle head linked to a polymer chain tail through a chemical linkage. Next, using the giant surfactant, a thin film is formed. Next the thin film formed from the giant surfactant is annealed such that the giant surfactant self-assembles into a desired nanostructure. The desired nanostructure is comprised of periodic major domains and minor domains. Finally, at least some of either the major domain or the minor domain is selectively removed to form the nanopatterned substrate.
