A method of manufacturing a light-emitting device using laser scribing to improve overall light output is disclosed. Upon placing a semiconductor wafer having light emitting diode (“LED”) devices separated by streets on a wafer chuck, the process arranges a first surface of semiconductor wafer containing front sides of the LED devices facing up and a second surface of semiconductor wafer containing back sides of the LED devices facing toward the wafer chuck. After aligning a laser device over the first surface of the semiconductor wafer above a street, the process is configured to focus a high intensity portion of a laser beam generated by the laser device at a location in a substrate closer to the back sides of the LED devices.
