Patent ID: 8637897

Claim:
A semiconductor light emitting device comprising: a plurality of light emitting cells arranged on a conductive substrate, each light emitting cell of the plurality of light emitting cells including a first-conductivity-type semiconductor layer, a second-conductivity-type semiconductor layer, and an active layer disposed between the first-conductivity-type semiconductor layer and the second-conductivity-type semiconductor layer, wherein the second-conductivity-type semiconductor layer of each light emitting cell of the plurality of light emitting cells is electrically connected to the conductive substrate; and a contiguous interconnection structure disposed on a to surface of the first-conductivity-type semiconductor layer of each light emitting cell and electrically connecting the first-conductivity-type semiconductor layer of one light emitting cell of the plurality of light emitting cells to the first-conductivity-type semiconductor layer of at least one other light emitting cell of the plurality of light emitting cells.
