Abstract
A light-emitting device comprises a semiconductor stack comprising a first semiconductor layer, a second semiconductor layer, and an active layer formed between the first semiconductor layer and the second semiconductor layer; a first pad on the semiconductor stack; a second pad on the semiconductor stack, wherein the first pad and the second pad are separated from each other with a distance, which define a region between the first pad and the second pad on the semiconductor stack; and multiple vias penetrating the active layer to expose the first semiconductor layer, wherein the first pad and the second pad are formed on regions other than the multiple vias.
