Title:
METHOD FOR PRODUCING LIGHT-EMITTING DIODE
Document Type and Number:
WIPO Patent Application WO/2018/135690
Kind Code:
A1
Abstract:
The present invention provides a method for producing a light-emitting diode. The method for producing a light-emitting diode according to an embodiment of the present invention comprises: a step of forming a mask layer, including at least one window region and at least one protruding region, on a growth substrate; a step of forming gallium nitride (GaN), comprising N-polar gallium nitride and Ga-polar gallium nitride, on the growth substrate by subjecting gallium nitride to epitaxial lateral overgrowth (ELOG); a step of selectively etching the N-polar gallium nitride; and a step of removing the mask layer, wherein the window region of the mask layer has a negative-type window pattern.
