Patent ID: 11749778

Abstract:
A semiconductor device according to an embodiment may include: a light emitting structure; a light transmitting electrode layer disposed on the light emitting structure; and a reflective layer disposed on the light transmitting electrode layer and including a plurality of first openings and a plurality of second openings. The semiconductor device according to the embodiment may include: a first electrode in contact with a first conductivity type semiconductor layer of the light emitting structure; and a second electrode in contact with the light transmitting electrode layer through the plurality of first openings. The first electrode may include a first sub-electrode and a plurality of first branch electrodes, wherein the plurality of first branch electrodes are arranged extending toward the second electrode from the first sub-electrode; the second electrode may include a second sub-electrode and a plurality of second branch electrodes, wherein the plurality of second branch electrodes are arranged extending toward the first electrode from the second sub-electrode; and the plurality of first branch electrodes and the plurality of second branch electrodes may be alternately disposed on an upper surface of the reflective layer.
