Classification: CPC H | IPC H

Claim 4:
5. The spherical flip-chip micro-LED of claim 4, wherein
the first semiconductor layer, the light-emitting layer, the second semiconductor layer, and the ITO current spreading layer form a hemispherical structure, the supporting body is a hemispherical structure;
the first semiconductor layer, the light-emitting layer, and the second semiconductor layer defines an electrode accommodating through hole which extends through and is perpendicular to the first semiconductor layer, the light-emitting layer, and the second semiconductor layer;
the second electrode is disposed in the electrode accommodating through hole, and has one end electrically coupled to the ITO current spreading layer and the other end is exposed outside a surface of the hemispherical structure formed by the light-emitting body;
an insulating protective layer is covered on outer surfaces of the first semiconductor layer, the light-emitting layer, the second semiconductor layer, and the ITO current spreading layer, and is covered on an inner surface of the electrode accommodating through hole; and
the insulating protective layer defines an electrode accommodating window thereon, wherein the first electrode is disposed in the electrode accommodating window, and has one end electrically coupled to the first semiconductor layer and the other end is exposed outside the surface of the hemispherical structure formed by the light-emitting body.
