Abstract:
1. A light emitting diode (LED) package comprising: a substrate comprising a top surface and a bottom surface; a first electrode and a second electrode spaced from the first electrode, both the first and the second electrodes being embedded in the substrate, both the first and the second electrodes comprising a top face and a bottom face, the top faces of the first and the second electrodes being exposed at the top surface of the substrate, and the bottom faces of the first and the second electrodes being exposed at the bottom surface of the substrate; an LED die mounted on the top surface of the substrate and respectively electrically connected to the first and the second electrodes, the LED die comprising a positive bonding pad (p-pad) and a negative bonding pad (n-pad); and an encapsulation layer covered on the top surface of the substrate to encapsulate the LED die therein; wherein the top face of the first electrode defines a first groove corresponding to the p-pad of the LED die, and at least a portion of the p-pad is inserted into the first groove, an oxidation-resistant metal coating layer being filled between an insertion portion of the p-pad and at least a portion of an inner surface of the first groove wherein the top face of the second electrode defines a second groove corresponding to the n-pad of the LED die, and at least a portion of the n-pad is inserted into the second groove, an oxidation-resistant metal coating layer being filled between an insertion portion of the n-pad and at least a portion of an inner surface of the second groove; and wherein a portion of the top surface of the substrate located between the first and the second electrodes protrudes from a plane shared by the top faces of the first and the second electrodes by a predetermined distance to reach a bottom side of the LED die.
