    摘要: The invention relates to a monolithic white light emitting device using wafer bonding or metal bonding. In the invention, a conductive submount substrate is provided. A first light emitter is bonded onto the conductive submount substrate by a metal layer. In the first light emitter, a p-type nitride semiconductor layer, a first active layer, an n-type nitride semiconductor layer and a conductive substrate are stacked sequentially from bottom to top. In addition, a second light emitter is formed on a partial area of the conductive substrate. In the second light emitter, a p-type AlGaInP-based semiconductor layer, an active layer and an n-type AlGaInP-based semiconductor layer are stacked sequentially from bottom to top. Further, a p-electrode is formed on an underside of the conductive submount substrate and an n-electrode is formed on a top surface of the n-type AlGaInP-based semiconductor layer.
