Title: LIGHT-EMITTING DIODE PROVIDED WITH SUBSTRATE HAVING PATTERN ON REAR SIDE THEREOF, AND METHOD FOR MANUFACTURING SAME
Abstract:
A method for manufacturing a light-emitting diode is provided. First, a substrate having a front side and a rear side is provided. An uneven pattern is formed on the rear side. A light-emitting semiconductor layer is formed by sequentially stacking a first semiconductor layer, an active layer, and a second semiconductor layer on the front side of the substrate having the uneven pattern. The light-emitting semiconductor layer and the substrate are separated into a plurality of light-emitting cells.
