LIGHT-EMITTING DEVICE AND MANUFACTURING METHOD THEREOF
First Claim
1. A manufacturing method of a light-emitting device comprising:
- providing a substrate having a surface, the surface including a plurality of protruding parts and a plurality of recess parts relative to the protruding parts;
forming an epitaxial blocking layer on the substrate, wherein the epitaxial blocking layer covers the recess parts and exposes the protruding parts; and
forming a light-emitting epitaxial structure on the substrate with the protruding parts serving as a growth surface thereof.

Abstract
A light-emitting device and a manufacturing method thereof are provided. The light-emitting device includes a substrate, an epitaxial blocking layer, and a light-emitting epitaxial structure. The substrate has a surface, in which the surface includes a plurality of protruding parts and a plurality of recess parts relative to the protruding parts. The epitaxial blocking layer disposed on the substrate covers the recess parts and exposes the protruding parts. The light-emitting epitaxial structure disposed on the substrate is connected to the protruding parts and is disposed above the recess parts. The light-emitting epitaxial structure is formed by using the protruding parts as a growth surface thereof so as to have a better crystalline quality.
