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.

Abstract: A light emitting diode (LED) is revealed. The LED includes a substrate, a first-type-doped layer, a light emitting layer, a second-type-doped layer, a plurality of first grooves, a second groove, an insulation layer, a first contact, and a second contact. The LED features that the second groove is connected to one end of each first groove and penetrates the second-type-doped layer and the light emitting layer to expose a part of the first-type-doped layer. The contact area between the first contact and the first-type-doped layer is increased. Therefore, the LED is worked at high current densities without heat accumulation. Moreover, the light emitting area is not reduced and the light emitting efficiency is not affected. The LED is flipped on a package substrate to form a flip-chip LED package.
