  • Patent number: 10566310
    Abstract: A microelectronic package includes at least one microelectronic element having a front surface defining a plane, the plane of each microelectronic element parallel to the plane of any other microelectronic element. An encapsulation region overlying edge surfaces of each microelectronic element has first and second major surfaces substantially parallel to the plane of each microelectronic element and peripheral surfaces between the major surfaces. Wire bonds are electrically coupled with one or more first package contacts at the first major surface of the encapsulation region, each wire bond having a portion contacted and surrounded by the encapsulation region. Second package contacts at an interconnect surface being one or more of the second major surface and the peripheral surfaces include portions of the wire bonds at such surface, and/or electrically conductive structure electrically coupled with the wire bonds.

  • Patent number: 9847238
    Abstract: Fan-out wafer-level packaging (WLP) using metal foil lamination is provided. An example wafer-level package incorporates a metal foil, such as copper (Cu), to relocate bonding pads in lieu of a conventional deposited or plated RDL. A polymer such as an epoxy layer adheres the metal foil to the package creating conductive contacts between the metal foil and metal pillars of a die. The metal foil may be patterned at different stages of a fabrication process. An example wafer-level package with metal foil provides relatively inexpensive electroplating-free traces that replace expensive RDL processes. Example techniques can reduce interfacial stress at fan-out areas to enhance package reliability, and enable smaller chips to be used. The metal foil provides improved fidelity of high frequency signals. The metal foil can be bonded to metallic pillar bumps before molding, resulting in less impact on the mold material.

  • Patent number: 9543277
    Abstract: A fan-out microelectronic package is provided in which bond wires electrically couple bond pads on a microelectronic element, e.g., a semiconductor chip which may have additional traces thereon, with contacts at a fan-out area of a dielectric element adjacent an edge surface of the chip. The bond wires mechanically decouple the microelectronic element from the fan-out area, which can make the electrical interconnections less prone to reliability issues due to effects of differential thermal expansion, such as caused by temperature excursions during initial package fabrication, bonding operations or thermal cycling. In addition, mechanical decoupling provided by the bond wires may also remedy other mechanical issues such as shock and possible delamination of package elements.
