Claim Text:
1. A semiconductor light emitting device, comprising: a supporting substrate having a first surface and a second surface opposite to the first surface; at least one semiconductor stack formed on the first surface, wherein each stack includes a plurality of semiconductor layers grown sequentially using a growth substrate and composed of a first semiconductor layer having a first conductivity, a second semiconductor layer having a second conductivity different from the first conductivity, and an active layer interposed between the first semiconductor layer and the second semiconductor layer and generating light via electron-hole recombination, and wherein a growth substrate-removed surface is formed on a side of the first semiconductor layer; a bonded layer, which bonds a second semiconductor layer side of the plurality of semiconductor layers to the first surface of the supporting substrate; and a bonded layer-removed surface formed on the first surface, being open towards the plurality of semiconductor layer, wherein at least two semiconductor stacks (which are referred to a first semiconductor stack and a second semiconductor stack) are provided, the supporting substrate has a first electrical pass transferring either electrons or holes and a second electrical pass transferring either holes or electrons, for each of the semiconductor stacks, with the first electrical pass continuing to the first surface from the second surface, the bonded layer is electrically connected with the first electrical pass, and the semiconductor light emitting device further comprises an electrical connection for connecting the first semiconductor stack on a side of the second surface with at least one of the first and second electrical passes of the second semiconductor stack, wherein the semiconductor light emitting device further comprises an additional electrical pass transferring either electrons or holes from the second electrical pass to the plurality of semiconductor layers.
