Abstract:
1. A light emitting diode (LED) package comprising: a substrate, comprising a top surface and a bottom surface at opposite sides thereof; a first electrode and a second electrode spaced from the first electrode, both the first and second electrodes penetrating downwardly through the substrate from the top surface to the bottom surface, a top face of each of the first and second electrodes being exposed at the top surface of the substrate, and a bottom face of each of the first and second electrodes being exposed at the bottom surface of the substrate; and an LED die arranged on the top surface of the substrate and electrically connected to the first and second electrodes, the LED die comprising a positive bonding pad and a negative bonding pad; wherein a cutout is defined on an edge portion of the top face of at least one of the first and second electrodes, an oxidation-resistant metal coating layer is filled in the cutout of the at least one of the first and second electrodes and directly contacts the substrate, and at least one of the positive and negative bonding pads of the LED die is electrically connected to a corresponding one of the first and second electrodes via the oxidation-resistant metal coating layer.
