  • 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.
