  • Patent number: 8803185
    Abstract: A light emitting diode package and a method of fabricating the same. The package includes a light emitting diode chip having a first surface and a second surface opposing the first surface, a metal frame (or TAB tape) having leads connected to the light emitting diode chip, and a light-pervious encapsulant encapsulating the light emitting diode chip, wherein the second surface of the chip is exposed from the first light-pervious encapsulant. The metal frame (or TAB tape) connects the light emitting diode chip to an external circuit board. The LED package does not need wire-bonding process. A method of fabricating a light emitting diode package is also provided.
    Type: Grant

  • Patent number: 5159750
    Abstract: A package for containing an integrated circuit component is provided which includes one or more layers with exposed edges surrounding a central opening. The integrated circuit component is positioned in the central opening. Bond wires connect the bond pads of the integrated circuit component to the continuous shelves of the various stepped-back stadium-like layers as well as to individual insulated leads. The layers are spaced apart by beads or columns of insulative material and the major portion of the layers are separated from each other by a gaseous dielectric, preferably air. The R-C constant is reduced and the speed of transmission is increased by the presence of the low dielectric material providing a device which can function rapidly. The stepped portions of the layers are exposed to allow for electrical interconnections within the layers, as well as from each layer to the integrated circuit.
