Abstract:
1. A light emitting diode package, comprising: a semiconductor substrate having a first surface and a second surface; at least a through-hole penetrating the first surface and the second surface of the semiconductor substrate; at least a heat dissipation hole extending partially through the semiconductor substrate from the second surface toward the first surface of the semiconductor substrate without penetrating the first surface; a thermal conductive material filled in the heat dissipation hole, forming a thermal via, wherein the thermal via has a first end near the first surface and a second end near the second surface; an insulating layer overlying a sidewall of the through-hole and extending overlying the first surface and the second surface of the semiconductor substrate, wherein the insulating layer further covers at least one of the first end, the second end and a sidewall of the thermal via; a conducting layer overlying the insulating layer in the through-hole and extending to the first surface and the second surface of the semiconductor substrate; and an LED chip disposed overlying the first surface or the second surface of the semiconductor substrate and having an electrode electrically connected to the conducting layer.
