  • Patent number: 8003448
    Abstract: A semiconductor package includes a rewiring substrate and a semiconductor chip. The semiconductor chip includes: a first face with an active surface including integrated circuit devices and chip contact pads, a second face lying in a plane essentially parallel to the first face and side faces. Each side face of the semiconductor chip lies in a plane essentially perpendicular to the first and second faces. At least one edge between two mutually essentially perpendicular faces of the semiconductor chip includes a surface.
    Type: Grant

  • Patent number: 7452747
    Abstract: A semiconductor package comprises a substrate which includes a plurality of conducting traces and upper contact areas on its upper surface and a second plurality of lower conductive traces and external contact areas on its bottom surface and external conducting members attached to the external contact areas. The semiconductor package also includes a semiconductor die comprising an active surface with a plurality of die contact pads, electrically connected to the contact areas of the substrate by conducting members. A support layer between the conducting members on the active surface of the semiconductor die covers at least the base portion of the conducting members. A method relates to the production of the semiconductor package.

  • Patent number: 6852567
    Abstract: A method of assembling a semiconductor device package includes first attaching a semiconductor device to a die-pad area of a leadframe. Electrical connections are then between electrical contact areas on the semiconductor device and electrical connection areas on the leadframe to form a device/leadframe assembly. An adhesion enhancing coating is then deposited on the exposed surface of the device frame/leadframe assembly before encapsulating the coated device leadframe assembly in an electrically insulating material.

  • Patent number: 6288335
    Abstract: A package for at least one semiconductor body. The package is characterized by being configured in two parts. A first part of the package contains a thin supporting frame which has a thickness of a few micrometers which completely surrounds the surface of the semiconductor body and is raised above a top surface of the semiconductor body at the edge of the semiconductor body. The second part of the package has a cover which is as flat as possible which covers the entire second surface and at least partially covers an upper rim of the supporting frame. A compound forming the supporting frame has a considerably greater viscosity than a compound forming the cover. The supporting frame is used as a flow stop for the covering compound during production of the package. Such so-called PBCSP packages allow packaged components to be produced which have an optimum chip/package ratio.
