ELECTRONIC PACKAGE
An electronic package is provided, in which an electronic element is arranged on a carrier structure having a plurality of wire-bonding pads arranged on a surface of the carrier structure, and a plurality of bonding wires are connected to a plurality of electrode pads of the electronic element and the plurality of wire-bonding pads. Further, among any three adjacent ones of the plurality of wire-bonding pads, a long-distanced first wire-bonding pad, a middle-distanced second wire-bonding pad and a short-distanced third wire-bonding pad are defined according to their distances from the electronic element. Therefore, even if the bonding wires on the first to third wire-bonding pads are impacted by an adhesive where a wire sweep phenomenon occurred when the flowing adhesive of a packaging layer covers the electronic element and the bonding wires, the bonding wires still would not contact each other, thereby avoiding short circuit problems.
Transparent light emitting diodes
A transparent light emitting diode (LED) includes a plurality of III-nitride layers, including an active region that emits light, wherein all of the layers except for the active region are transparent for an emission wavelength of the light, such that the light is extracted effectively through all of the layers and in multiple directions through the layers. Moreover, the surface of one or more of the III-nitride layers may be roughened, textured, patterned or shaped to enhance light extraction.
