Abstract:
1. A method for manufacturing a light emitting diode device, comprising: forming a stacked epitaxial structure on an epitaxial substrate; removing a portion of the stacked epitaxial structure and a portion of the epitaxial substrate to form at least a hole extending into the epitaxial substrate, wherein the hole exposes a plurality of sidewalls of the stacked epitaxial structure and a portion of the epitaxial substrate; forming an insulating protective layer on the sidewalls of the stacked epitaxial structure and the portion of the epitaxial substrate exposed; forming at least a temporary substrate overlying the stacked epitaxial structure, the insulating protective layer, and the sidewalls of the stacked epitaxial structure for supporting the stacked epitaxial structure with the sidewalls; removing the epitaxial substrate to expose a bottom surface of the stacked epitaxial structure and a portion of the insulating protective layer; forming at least a heat-conductive plate beneath the stacked epitaxial structure; and removing the temporary substrate to automatically separate the stacked epitaxial structure into a plurality of LED devices.
