Abstract:
1. A manufacturing method of a semiconductor light-emitting device, comprising: forming a first type doped semiconductor structure on a substrate, the first type doped semiconductor structure comprising a base and a plurality of columns extending outward from the base, and each of the columns comprises a plurality of sidewall surfaces and a top surface; forming a light-emitting layer on the sidewall surfaces and the top surface, wherein a surface area of the light-emitting layer gradually changes from a side adjacent to the columns to a side away from the columns; forming a second type doped semiconductor layer on the light-emitting layer; forming a first conductive layer on the second type doped semiconductor layer, wherein the first conductive layer is in direct contact with a top surface and sidewalls of the second type doped semiconductor layer; forming a dielectric layer between the columns, the dielectric layer exposing the first conductive layer located on the top surface of each of the columns, wherein the dielectric layer comprises at least one of a plurality of quantum dots, a plurality of phosphors, and a plurality of metal nanoparticles; and forming a current restraining structure on the top surface of the columns before forming the light-emitting layer, wherein the sidewall surfaces of the columns are not covered by the current restraining structure.
