Patents by Inventor Yong Bo Yang

Yong Bo Yang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9472532
    Abstract: Embodiments of the present invention are directed to leadframe area array packaging technology for fabricating an area array of I/O contacts. A manufactured package includes a polymer material substrate, an interconnect layer positioned on top of the polymer material substrate, a die coupled to the interconnect layer via wire bonds or conductive pillars, and a molding compound encapsulating the die, the interconnect layer and the wire bonds or conductive pillars. The polymer material is typically formed on a carrier before assembly and is not removed to act as the substrate of the manufactured package. The polymer material substrate has a plurality of through holes that exposes the interconnect layer at predetermined locations and enables solder ball mounting or solder printing directly to the interconnect layer. In some embodiments, the semiconductor package includes a relief channel in the polymer material substrate to improve the reliability performance of the manufactured package.

  • Publication number: 20160043041
    Abstract: Semiconductor packages and methods for forming a semiconductor package are presented. The method includes providing a package substrate having first and second major surfaces. The package substrate dudes at least one substrate layer having at least one cavity. Interconnect structure is formed. At least one conductive stud is formed within the cavity and a conductive trace and a connection pad are formed over the first major surface of the package substrate and are coupled to top surface of the conductive stud. A package pad is formed and is directly coupled to the conductive stud. A die having conductive contacts on its first or second surface is provided. The conductive contacts of the die are electrically coupled to the interconnect structure. A cap is formed over the package substrate to encapsulate the die.
