  • Patent number: 10991644
    Abstract: A method of providing a sensor IC package can include applying a film to a leadframe having first and second surfaces, mounting at least one component to the film, and applying a pre-mold material to cover at least a portion of the leadframe and the passive component while leaving a first side of the leadframe exposed. The film can be removed and a die attached to the first side of the leadframe. At least one electrical connection can be formed between the die and the leadframe. The assembly of the die, the leadframe, and the pre-mold material can be encapsulated with a final mold material to provide a low profile IC package.

  • Patent number: 8598690
    Abstract: A semiconductor device is made by mounting a plurality of semiconductor die to a substrate, depositing an encapsulant over the substrate and semiconductor die, forming a shielding layer over the semiconductor die, creating a channel in a peripheral region around the semiconductor die through the shielding layer, encapsulant and substrate at least to a ground plane within the substrate, depositing a conductive material in the channel, and removing a portion of the conductive material in the channel to create conductive vias in the channel which provide electrical connection between the shielding layer and ground plane. An interconnect structure is formed on the substrate and are electrically connected to the ground plane. Solder bumps are formed on a backside of the substrate opposite the semiconductor die. The shielding layer is connected to a ground point through the conductive via, ground plane, interconnect structure, and solder bumps of the substrate.

  • Publication number: 20100059783
    Abstract: A light emitting chip package includes a planar substrate, an LED die mounted on the substrate, and one or more relatively wide and thick metal leads to serve as a low thermal resistance path. The substrate comprises a chip mounting area and a wire bond area on a dielectric body. The LED die is seated on the chip mounting area and electrically connected to the wire bonding area. The metal leads are attached to the substrate and form terminals for external connection. At least one metal lead is connected to the chip mounting area to serve as a low thermal resistance path between the chip mounting area and an external heat sink.
