Abstract:
A package structure for a light emitting diod having a substrate and two electrodes, comprising:an insulating carrier base formed with a through hole, the through hole having a lower opening facing a rear surface of the substrate, an upper opening, and at least a stepwise portion connected between the lower opening at the upper opening, in which the at least a stepwise portion has a lower sidewall surface connected to the lower opening, an intermediate mesa plane, and an upper sidewall surface connected to the upper opening, and a depth of the through hole is large enough for accommodating the light emitting diode; at least a planar metal layer formed on both of the intermediate mesa plane and the upper sidewall surface of the at least a stepwise portion; at least a metal pad formed in a region other than the through hole on a top surface of the insulating carrier base and connected to the at least a planar metal layer; at least a wiring for connecting a portion of the at least a planar metal layer located on the intermediate mesa plane and one of the two electrodes; a first resin for filling the lower opening in order to support the substrate of the light emitting diode and serve as a light-transmitting channel; and a second resin for filling the upper opening in order to seal the light emitting diode and the at least a wiring.
