Patent ID: 8129739

Claim:
A semiconductor light emitting device comprising: an optically transparent device board; a first semiconductor layer which is formed on the device board so as to cover the device board and which is one of a p-type semiconductor layer and an n-type semiconductor layer; a first electrode layer formed on the first semiconductor layer; a second semiconductor layer which is the other of the p-type semiconductor layer and the n-type semiconductor layer, the second semiconductor layer being formed on an area other than where the first electrode layer is formed on the first semiconductor layer, and for emitting light between the first semiconductor layer and the second semiconductor layer; a second electrode layer formed on the second semiconductor layer; one first bump formed on the first electrode layer, wherein the first bump is the only bump formed on the first semiconductor layer; and a plurality of second bumps formed on the second electrode layer, wherein the first bump and the second bumps are formed in an identical shape and an identical size, wherein the first bump is arranged with one symmetrical grid array of the second bumps, wherein the first bump is placed at the center of the one symmetrical grid array, and wherein the first electrode layer forms a cross-shaped area centered in a block of four adjacent second bumps formed on the second electrode layer.
