Patent ID: 10763395

Abstract:
A flip-chip light emitting diode element capable of reducing lateral resistance. The flip-chip light emitting diode element includes a stacked body structure configured by sequentially stacking a first n-type group III nitride semiconductor layer having a carrier concentration that is at least 1×1019 cm−3 but less than 3×1020 cm−3, a second n-type group III nitride semiconductor layer having a carrier concentration that is at least 5×1017 cm−3 but less than 1×1019 cm−3, a light-emitting layer formed by a group III nitride semiconductor, and a p-type group III nitride semiconductor layer. A height of unevenness on an interface between the first n-type group III nitride semiconductor layer and the second n-type group III nitride semiconductor layer is greater than that of unevenness of an interface between the second n-type group III nitride semiconductor layer and the light emitting layer.
