Abstract:
1. A method for manufacturing a semiconductor light emitting diode, comprising the steps of: a) preparing a conductive substrate whose top surface has a plurality of three-dimensional shapes, wherein the three-dimensional shapes comprise a first surface, and second and third surfaces inclined to and intersecting with the first surface; b) sequentially growing an n-type nitride semiconductor layer, an active layer, and a p-type nitride semiconductor layer on the first, second, and third surfaces of the conductive substrate, thereby forming a three-dimensional light-emitting stack structure; c) forming a plurality of p-electrodes on the p-type nitride semiconductor layer; d) forming a plurality of n-electrodes on a bottom surface of the conductive substrate; e) removing portions of the light-emitting stack structure to expose the conductive substrate where the second and third surfaces intersect with the first surface; and f) separating the resulting structure into individual devices.
