SEMICONDUCTOR DEVICE AND SEMICONDUCTOR DEVICE PACKAGE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2018/135908
Kind Code:
A1
Abstract:
Disclosed is in the embodiment is a semiconductor device comprising: a first conductive semiconductor layer; a second conductive semiconductor layer; an active layer disposed between the second conductive semiconductor layer and the second conductive semiconductor layer; a first electrode electrically connected to the first conductive semiconductor layer; and a second electrode electrically connected to the second conductive semiconductor layer, wherein the first conductive semiconductor layer includes a first sub-semiconductor layer, a third sub-semiconductor layer and a second sub-semiconductor layer disposed between the first sub-semiconductor layer and the third sub-semiconductor layer, wherein aluminum composition of the first sub-semiconductor layer and the third sub-semiconductor layer is larger than an aluminum composition of the active layer, and an aluminum composition of the second sub-semiconductor layer is smaller than the aluminum composition of the first sub-semiconductor layer and the third sub-semiconductor layer, wherein the second conductive semiconductor layer includes a current injection layer of which aluminum composition decreases as a distance from the active layer increases, the first electrode is disposed on the second sub-semiconductor layer, the second electrode is disposed on the current injection layer, and the ratio of the average value of the aluminum composition of the second sub-semiconductor layer to the average value of the aluminum composition of the current injection layer is 1:0.12 to 1:1.6.
