Abstract
A light-emitting semiconductor apparatus includes a light-emitting structure, a reflective structure, and a carrier. The light-emitting structure includes a first type semiconductor layer, a second type semiconductor layer, and a light-emitting layer positioned between the first type semiconductor layer and the second type semiconductor layer. The reflective structure has a first transparent conductive layer, a first patterned reflective layer, a second transparent conductive layer, and a second patterned reflective layer. The first patterned reflective layer is disposed between the first transparent conductive layer and the second transparent conductive layer, and has an opening for physically connecting the first transparent conductive layer and the second transparent conductive layer. The second transparent conductive layer is disposed between the first patterned reflective layer and the second patterned reflective layer. The second patterned reflective layer is positioned on an area corresponding to the opening. The light-emitting structure and the carrier are respectively on two sides of the reflective structure.
