Assignee: LUMILEDS, LLC
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A micro-light emitting diode (uLED) comprising:
a mesa comprising:
a plurality of semiconductor layers including an n-type layer, an active layer, and a p-type layer;
a p-contact layer contacting the p-type layer;
the mesa comprising a height spanning from a top surface of the p-contact layer to a bottom surface of the n-type layer and a width spanning a first sidewall of the n-type layer to a second sidewall of the n-type layer; the top surface of the p-contact layer having a different planar orientation compared to the first and second sidewalls of the n-type layer;

a cathode contacting the first sidewall of the n-type layer;
a first region of dielectric material that insulates the p-contact layer, the active layer, and a first sidewall of the p-type layer from the cathode;
an anode contacting the top surface of the p-contact layer; and
a second region of dielectric material that insulates the active layer, a second sidewall of the p-type layer, and the second sidewall of the n-type layer from the anode;
the cathode and the anode longitudinally spanning the uLED.
