LIGHT EMITTING DIODE HAVING MULTIPLE ACTIVE LAYERS AND METHOD OF MANUFACTURING THE SAME

摘要

A semiconductor light emitting device having multiple active layers and a manufacturing method thereof are provided to prevent rapid saturation of an output light due to injection current by enlarging an area of the active layer twice. A light emitting layer having plural active layers is deposited on a substrate(10). The light emitting layer is formed by depositing plural light emitting diode modules(20) each having the active layer, in which adjacent semiconductor layers(21,23) have the same shape. The semiconductor layer has a metal electrode layer(40) to allow an electric current to flow through each semiconductor layer. An insulating layer(30) is formed between a side of the metal electrode layer and a side of the light emitting layer to restrict inflow of the current into the light emitting layer from the side of the metal electrode layer.
