Patent ID: 8455332

Claim:
A method of manufacturing a light-emitting device, comprising: placing a semiconductor wafer having a plurality of light emitting diode (“LED”) devices deposited over a substrate separated by a plurality of streets on a wafer chuck; arranging a first surface of the semiconductor wafer containing the LED devices facing away from the wafer chuck and a second surface of the semiconductor wafer opposite to the first surface of the semiconductor wafer containing the LED devices facing toward the wafer chuck; aligning a laser device over the first surface of the semiconductor wafer above a street of the plurality of streets; focusing a high intensity laser beam generated by the laser device at a location inside the substrate closer to the second surface than that of the first surface through the first surface of the semiconductor wafer; wherein focusing a high intensity laser beam includes allowing a portion of the laser beam to penetrate a portion of one of the LED device without occurrence of substantial photon absorption; and moving the laser device in a direction parallel to the semiconductor wafer to create a scribing line that is closer to the second surface than that of the first surface.
