Patent ID: 8866179

Claim:
A protection structure for formation of a semiconductor light emitting device comprising: a semiconductor layer having a first main surface, a second main surface opposite side to the first main surface, and a light emitting layer; a first electrode provided on the second main surface in a region where the light emitting layer is provided; a second electrode provided on the second main surface; an insulating layer provided on the second main surface side of the semiconductor layer and including a first opening that reaches the first electrode and a second opening that reaches the second electrode; a first interconnection layer provided on a surface of the insulating layer opposite to a surface facing the semiconductor layer and provided in the first opening, the first interconnection layer being connected to the first electrode; a second interconnection layer provided on a surface of the insulating layer opposite to a surface facing the semiconductor layer and provided in the second opening, the second interconnection layer being connected to the second electrode; a first metal pillar provided on a surface of the first interconnection layer opposite to a surface facing the first electrode; a second metal pillar provided on a surface of the second interconnection layer opposite to a surface facing the second electrode; a resin layer provided between a side surface of the first metal pillar and a side surface of the second metal pillar; and a conducting polymer film provided on a surface of the resin layer between the first metal pillar and the second metal pillar, the conducting polymer film electrically connecting the first metal pillar and the second metal pillar, and shorting the first metal pillar and the second metal pillar, the conducting polymer film provided on side surfaces of the insulating layer and the resin layer, the side surfaces being not parallel to the first main surface.
