Patent ID: 11870011
Assignee: BEIJING BOE TECHNOLOGY DEVELOPMENT CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 12:
13. A method of manufacturing a light-emitting diode, comprising:
providing a base;
forming, on the base, a second semiconductor layer, a light-emitting layer and a first semiconductor layer sequentially on top of one another;
patterning the first semiconductor layer to remove a part of the first semiconductor layer at an edge of a light-emitting region of the light-emitting diode;
forming a first barrier film at a side of the base at which the patterned first semiconductor layer has been formed; and
patterning the first barrier film to retain a part of the first barrier film covering a side face of the patterned first semiconductor layer and form a first barrier layer; wherein the first barrier layer is configured to form a charge depletion region between the first barrier layer and the first semiconductor layer.
