LIGHT-EMITTING DEVICE AND METHOD FOR MANUFACTURING THE SAME

A method for manufacturing a light-emitting device comprises the steps of: providing a first substrate; forming a semiconductor structure on the first substrate, wherein the semiconductor structure comprises a first type semiconductor layer, a second type semiconductor layer, and an active layer between the first type semiconductor layer and the second type semiconductor layer; forming an isolation region through the second type semiconductor and the active layer to separate the semiconductor structure into a first part and a second part on the first substrate; and injecting an electrical current with a current density to the second part to make the second part to be permanently broken-down; wherein after the second part is permanently broken-down, the first part is capable of generating electromagnetic radiation and the second part is incapable of generating electromagnetic radiation.
