Abstract:
A wafer-level packaging process of a light-emitting diode is provided. First, a semiconductor stacked layer is formed on a growth substrate. A plurality of barrier patterns and a plurality of reflective layers are then formed on the semiconductor stacked layer, wherein each reflective layer is surrounded by one of the barrier patterns. A first bonding layer is then formed on the semiconductor stacked layer to cover the barrier patterns and the reflective layers. Thereafter, a carrying substrate having a plurality of second bonding layers and a plurality of conductive plugs electrically insulated from each other is provided, and the first bonding layer is bonded with the second bonding layer. The semiconductor stacked layer is then separated from the growth substrate. Next, the semiconductor stacked layer is patterned to form a plurality of semiconductor stacked patterns. Next, each semiconductor stacked pattern is electrically connected to the conductive plug.

A semiconductor light emitting structure including a substrate, a second type electrode layer, a reflecting layer, an insulating layer, a first type electrode layer, a first type semiconductor layer, an active layer and a second type semiconductor layer is provided. The second type electrode layer formed on the substrate has a current spreading grating formed by several conductive pillars and conductive walls, which are staggered and connected to each other. The reflecting layer and the insulating layer are formed on the second type electrode layer in sequence, and cover each conductive pillar and each conductive wall. The first type electrode layer, the first type semiconductor layer and the active layer are formed on the insulating layer in sequence. The second type semiconductor layer is formed on the active layer, and covers each conductive pillar and each conductive wall.
