| 摘要 |
The invention provides a light emitting device with uniform light emission, wherein the light emitting device comprises an alloyed film formed on the p-type semiconductor layer. The alloyed film has a structure of long-range order superlattice, and is formed by annealing a multi-metal layer. The alloyed film has superior thermal conductivity and superior electrical conductivity. Thus, the current is uniformly applied to the entire p-type semiconductor layer, and the light emitting device emits uniform light.
