  • Publication number: 20120273946
    Abstract: A semiconductor device entirely having a small height, which performs a fan-out operation for input/output signals and forms a short electrical path is provided. The semiconductor device includes a first semiconductor die having a first surface, a second surface opposed to the first surface, a third surface connecting the first and second surfaces to each other, a first bond pad disposed on the first surface, and a first through electrode passing between the first surface and second surface and electrically connected to the first bond pad. A first redistribution part is disposed under the second surface and includes a first redistribution layer electrically connected to the first through electrode. A second redistribution part is disposed over the first surface and includes a second redistribution layer electrically connected to the first bond pad.

  • Patent number: 8089145
    Abstract: In accordance with the present invention, there is provided a semiconductor package (e.g., a QFP package) including a uniquely configured leadframe sized and configured to maximize the available number of exposed leads in the semiconductor package. More particularly, the semiconductor package of the present invention includes a generally planar die pad or die paddle defining multiple peripheral edge segments. In addition, the semiconductor package includes a plurality of leads. Some of these leads are provided in two concentric rows or rings which at least partially circumvent the die pad, with other leads including portions which protrude from respective side surfaces of a package body of the semiconductor package. Connected to the top surface of the die pad is at least one semiconductor die which is electrically connected to at least some of the leads. At least portions of the die pad, the leads, and the semiconductor die are encapsulated by the package body.

  • Patent number: 7982298
    Abstract: In accordance with the present invention, there is provided multiple embodiments of a package-in-package semiconductor device including shortened electrical signal paths to optimize electrical performance. In each embodiment, the semiconductor device comprises a substrate having a conductive pattern formed thereon. In certain embodiments, a semiconductor package and one or more semiconductor dies are vertically stacked upon the substrate, and placed into electrical communication with the conductive pattern thereof. One or more of the semiconductor dies may include through-silicon vias formed therein for facilitating the electrical connection thereof to the conductive pattern of the substrate or to other electronic components within the vertical stack. Similarly, the semiconductor package may be provided with through-mold vias to facilitate the electrical connection thereof to other electronic components within the vertical stack.

  • Patent number: 6897550
    Abstract: A memory card comprising a leadframe having at least one die pad, a plurality of contacts, and a plurality of conductive traces extending from respective ones of the contacts toward the die pad. The traces are bent in a manner wherein the die pad and the contacts extend along respective ones of spaced, generally parallel frame planes. Disposed on and extending from the die pad and the traces is a plurality of stand-offs. At least one semiconductor die is attached to the die pad and electrically connected to at least one of the traces. A body at least partially encapsulates the leadframe and the semiconductor die such that the contacts are exposed in a bottom surface defined by the body.
