A patterned epitaxial substrate includes a substrate and a plurality of patterns. The substrate has a first zone and a second zone surrounding the first zone. The first zone is disposed around a center of the substrate. The patterns and the substrate are integrally formed, and the patterns are disposed on the substrate. The patterns include a plurality of first patterns and a plurality of second patterns. The first patterns are disposed in the first zone. The second patterns are disposed in the second zone. Sizes of the first patterns are different from sizes of the second patterns.

Patterned epitaxial substrate and semiconductor structure

A micro light-emitting device includes an epitaxial structure layer, a first-type electrode, a second-type electrode, and a light guide structure. The epitaxial structure layer has a top surface and a bottom surface opposite to each other and a plurality of first grooves located on the top surface. The first-type electrode and the second-type electrode separated from each other are disposed on the epitaxial structure layer and located at the bottom surface. The light guide structure is disposed on the epitaxial structure layer. The light guide structure covers a portion of the top surface and a portion of inner walls of the first grooves to define a plurality of second grooves corresponding to the portion of the first grooves.
