Abstract:
1. A method for fabricating a light-emitting diode device, comprising: providing a carrier having a first surface and a second surface on opposite sides of the carrier, wherein the first surface has a plurality of insulating micro patterns, and wherein the carrier and the plurality of insulating micro patterns are formed by different materials; growing a buffer layer, a first-type semiconductor layer, a light-emitting layer and a second-type semiconductor layer on the first surface of the carrier in sequence to form a light-emitting lamination layer; providing a substrate for the second-type semiconductor layer of the light-emitting lamination layer to bond on; performing a laser lift-off process to lift off the carrier from the light-emitting lamination layer, and surfaces of the plurality of insulating micro patterns and a surface of the buffer layer between the plurality of insulating micro patterns are exposed; removing the plurality of insulating micro patterns and the buffer layer to form a plurality of recess structures on the first-type semiconductor layer; and performing a surface-roughing process on a plurality of surfaces of the plurality of recess structures.
