  • Patent number: 9368361
    Abstract: In one embodiment, a method for forming an electronic device includes providing a substrate having a plurality of electronic devices formed therein, forming a protective layer over a major surface of the substrate containing the plurality of electronic devices, forming a mold layer over the protective layer, thinning a major surface of the substrate opposite to the major surface containing the plurality of electronic devices, and removing the adhesive layer and the mold layer. In another embodiment, a zone coating layer can be included between the protective layer and the mold layer.

  • Patent number: 8004078
    Abstract: Provided is an adhesive composition for a semiconductor device. For example, the adhesive composition comprises a binder resin and a silicon carbide filler. The silicon carbide filler has relatively high thermal conductivity and a relatively low coefficient of thermal expansion (CTE). Accordingly, the adhesive composition containing the silicon carbide filler exhibits improved heat dissipation performance and electrical performance due to high thermal conductivity and shows inhibition of delamination or cracking of semiconductor devices due to low CTE. The silicon carbide has high thermal conductivity, but is electrically non-conductive. Therefore, an electrically conductive adhesive can be obtained by additional incorporation of a silver (Ag) filler into the binder resin.

  • Patent number: 7906855
    Abstract: In accordance with the present invention, there is provided multiple embodiments of a semiconductor package including two or more semiconductor dies which are electrically connected to an underlying substrate through the use of conductive wires, some of which may be fully or partially encapsulated by an adhesive or insulating layer of the package. In a basic embodiment of the present invention, the semiconductor package comprises a substrate having a conductive pattern disposed thereon. Electrically connected to the conductive pattern of the substrate are first and second semiconductor dies. The first semiconductor die and a portion of the substrate are covered by an adhesive layer. The second semiconductor die, the adhesive layer and a portion of the substrate are in turn covered by a package body of the semiconductor package.

  • Patent number: 7847386
    Abstract: In accordance with the present invention, there is provided multiple embodiments of a reduced size stackable semiconductor package. In a basic embodiment of the present invention, the semiconductor package comprises a bulk layer having at least one first bond pad formed therein. At least one active layer is formed on the bulk layer and electrically coupled to the first bond pad. Additionally, at least one second bond pad is formed on the active layer and is electrically coupled thereto. A protection layer is formed on that surface of the active layer having the second bond pad formed thereon, the protection layer also partially encapsulating the second bond pad. In other embodiments of the present invention, the above-described semiconductor package is provided in a stacked arrangement and in a prescribed pattern of electrical communication with one or more additional, identically configured semiconductor packages.
