Abstract
A group III-V element-based flip-chip assembled light-emitting diode structure with electrostatic protection capacity. A first conductive buffer layer and a second conductive buffer layer are formed over a transparent substrate. An active layer structure, a contact layer, an electrode is formed over the first conductive buffer layer. The active layer structure, the contact layer and the electrode together form a light-emitting diode structure. A metallic electrode is formed over the second conductive buffer layer to form a Schottky diode. Alternatively, a doped region is formed within the second conductive buffer layer to form a homo-junction diode structure. The anode and cathode of the diode above the second conductive buffer layer are electrically connected to the cathode and anode of the light-emitting diode, respectively.
