Patent number: 10770413Abstract: 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.Type: GrantFiled: October 23, 2018Date of Patent: September 8, 2020Assignee: SHENZHEN GOODIX TECHNOLOGY CO., LTD.Inventors: Baoquan Wu, Xinfei Yu

Patent number: 9228069Abstract: 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.Type: GrantFiled: May 2, 2014Date of Patent: January 5, 2016Assignee: The University of AkronInventors: Stephen Z. D. Cheng, Wenbin Zhang, Kan Yue, Xinfei Yu, I-Fan Hsieh
