Zusammenfassung:A method for separating LEDs from each other includes such steps as generating N-type semiconductor layer on substrate, generating multiple LEDs with N-type semiconductor layer for connecting their laser emitting areas together, removing the N-type semiconductor layer around the LED and laser emitting area, generating the material layer of LED, generating cutting lines on the back of substrate between LEDs, and separating LEDs from each other along the cutting lines. Its advantages are clean surface of LED and less failure.
