摘要： A flip-chip light emitting diode with high light-emitting efficiency is disclosed. The LED includes a transparent conductive layer, an oxide layer, a reflective metal layer, a conductive layer, and a protective diffusion layer sequentially disposed over a p-type semiconductor layer. Thereby, light emitting from a light-emitting layer toward the p-type semiconductor layer is reflected and penetrating a transparent substrate and emitting outwards. Thus the problem of light shielded from the flip-chip type LED is solved and the light-emitting efficiency is improved. Furthermore, the present invention disposes the LED chip in a face-down orientation on a conductive substrate by flip-chip technology so as to enhance heat-dissipation efficiency of the LED.

摘要： The present invention relates to a light-emitting diode (LED) and a method for manufacturing the same. The LED comprises an LED die, one or more metal pads, and a fluorescent layer. The characteristics of the present invention include that the metals pads are left exposed for the convenience of subsequent wiring and packaging processes. In addition, the LED provided by the present invention is a single light-mixing chip, which can be packaged directly without the need of coating fluorescent powders on the packaging glue. Because the fluorescent layer and the packaging glue are not processed simultaneously and are of different materials, the stress problem in the packaged LED can be reduced effectively.
