摘要 |
The invention provides a light-emitting device, where the active region thereof may be escaped from being damaged by the plasma process. The device is first formed with a semiconductor layer on the semiconductor substrate, next provided with an etching mask. Using the mask, the semiconductor layer on the substrate is dry-etched to form a periodic structure with grooves and mesas. The active regions are buried within the grooves by the OMVPE method.
