SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/151553
Kind Code:
A1
Abstract:
Disclosed in an embodiment is a semiconductor device comprising: a semiconductor structure including a first-conductive type semiconductor layer, a second-conductive type semiconductor layer, and an active layer disposed between the first-conductive type semiconductor layer and the second-conductive type semiconductor layer; a first electrode electrically connected to the first-conductive type semiconductor layer; and a second electrode electrically connected to the second-conductive type semiconductor layer, wherein the semiconductor structure includes a first upper surface on which the first electrode is disposed, a second upper surface on which the second electrode is disposed, and an inclined surface disposed between the first upper surface and the second upper surface, a ratio of a first minimum height from the bottom surface of the semiconductor structure to the second upper surface and a second minimum height from the bottom surface of the semiconductor structure to the first upper surface is 1:0.6 to 1:0.95, and a difference between the first minimum height and the second minimum height is less than 2 μm.
