Abstract:
A light-emitting device includes a semiconductor light emitting stack and an electrode on the semiconductor light emitting stack, wherein the electrode includes a mirror layer, an adhesion layer inserted between the mirror layer and the semiconductor light emitting stack, a bonding layer, and a barrier layer inserted between the mirror layer and the bonding layer and covering the mirror layer to prevent the mirror layer from reacting with the bonding layer, wherein the barrier layer includes a first pair of different metals.
