    Abstract: A light emitting diode including a first doped layer, a light emitting layer, a second doped layer and a substrate is provided. A plurality of first grooves penetrate through the second doped layer and the light emitting layer. Thus, a partial surface of the first doped layer is exposed. At least one of the plurality of first grooves extends to edges of the second dope layer and the light emitting layer. An insulating layer is disposed over a part of second doped layer and extends to sidewalls of the first grooves. A first contact is set in the first grooves and electrically connected to the first doped layer. A second contact is set on the second doped layer and electrically connected to the second doped layer. By the first grooves, the first contact can be electrically connected to the first doped layer for improving current spreading.

    Abstract: The present invention relates to a light emitting diode (LED) and a flip-chip packaged LED device. The present invention provides an LED device. The LED device is flipped on and connected electrically with a packaging substrate and thus forming the flip-chip packaged LED device. The LED device mainly has an Ohmic-contact layer and a planarized buffer layer between a second-type doping layer and a reflection layer. The Ohmic-contact layer improves the Ohmic-contact characteristics between the second-type doping layer and the reflection layer without affecting the light emitting efficiency of the LED device and the flip-chip packaged LED device. The planarized buffer layer id disposed between the Ohmic-contact layer and the reflection layer for smoothening the Ohmic-contact layer and hence enabling the reflection layer to adhere to the planarized buffer layer smoothly. Thereby, the reflection layer can have the effect of mirror reflection and the scattering phenomenon on the reflected light can be reduced as well.
