Abstract:
A method of manufacturing a light-emitting device is disclosed. The method includes providing a light-emitting diode wafer, including a substrate and a semiconductor stack on the substrate, wherein the semiconductor stack has a lower surface facing the substrate and an upper surface opposite to the lower surface; providing a first laser on the light-emitting diode wafer and irradiating the light-emitting diode wafer from the upper surface to form a plurality of scribing lines on the upper surface; providing an etching process; providing and focusing a second laser on an interior of the substrate to form one or a plurality of textured areas in the substrate; and providing force on the light-emitting diode wafer to separate the light-emitting diode wafer into a plurality of light-emitting diode chips along the plurality of scribing lines.

Claim (Index 6):
The method of  claim 1 , wherein the step of providing and focusing the second laser on the interior of the substrate comprises performing the second laser in the substrate one time to form the one textured area, or multiple times to form the plurality of textured areas on the same cross section of the substrate; and wherein the second laser is a stealth dicing laser.
