Claim 33:
34. A back emission micro-light emitting diode (microLED) comprising:
a first semiconductor layer doped with a dopant selected from the dopant group consisting of n and p type dopants, the first doped semiconductor layer having a first top surface formed in a first plane and a second top surface formed in an overlying second plane, and having a bottom emission surface;
a multiple quantum well (MQW) layer having a top surface formed in a third plane, overlying the first doped semiconductor second top surface;
a second semiconductor doped with the unselected dopant type from the dopant group, formed as a layer having a top surface in a fourth plane, overlying the MQW layer;
an electrical insulator overlying the top surface of the second doped semiconductor and the first top surface of the first doped semiconductor;
a first electrode overlying and connected to the first doped semiconductor first top surface through a first via, and having a substrate interface surface in at least a fifth plane;
a second electrode overlying and connected to the second doped semiconductor through a second via, and having a substrate interface surface in a sixth plane; and,
wherein an electrode selected from the group consisting of the first electrode and the second electrode is formed as a ring at least partially surrounding an unselected electrode.
