Light-emitting device and method for manufacturing the same

A method for manufacturing a light-emitting device comprising 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 exceed a breakdown voltage of the second part to cause the second part to function as a low-resistance resistor and lose its diode behavior;
• wherein after the diode behavior of the second part is permanently destroyed, the active layer in the first part is capable of generating light and the active layer in the second part is incapable of generating light.
