Title:
SEMICONDUCTOR DEVICE AND SEMICONDUCTOR DEVICE PACKAGE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2018/212416
Kind Code:
A1
Abstract:
The present invention relates to a semiconductor device. A semiconductor device according to an embodiment comprises: a substrate; a first conductive semiconductor layer disposed on the substrate; an active layer disposed on the first conductive semiconductor layer; and a second conductive semiconductor layer disposed on the active layer. A first semiconductor layer, a second semiconductor layer, and a third semiconductor layer, which are different from each other in indium (In) content, are included between the first conductive semiconductor layer and the active layer. The first semiconductor layer is disposed to be adjacent to the active layer, the second semiconductor layer is disposed below the first semiconductor layer, and the third semiconductor layer is disposed below the second semiconductor layer. The indium content decreases in a direction from the active layer to the third semiconductor layer, and the indium content in the third semiconductor layer may be 5% to 10% of the indium content in the active layer.
