Claim 9:
10. A method for manufacturing a spherical flip-chip micro-LED, comprising:
forming sequentially a light-emitting structure layer and a supporting structure layer on a substrate;
etching the supporting structure layer to obtain a supporting body, wherein the supporting body is a hemispherical structure and transparent;
flipping over and stripping the substrate, and etching the light-emitting structure layer into a hemispherical structure;
perforating the hemispherical structure formed by the light-emitting structure layer to form an electrode accommodating through hole;
depositing an insulating protective layer which is covered on an outer surface of the light-emitting structure layer and an inner surface of the electrode accommodating through hole;
etching the insulating protective layer to form an electrode accommodating window; and
depositing a first electrode and a second electrode.
