Abstract
A multi-LED structure comprises a first LED and a separate second LED disposed on a common multi-LED native substrate. The LEDs each comprise a common first layer having a cantilever portion and a base portion and a common second layer having a light-emitting emission portion disposed only over the base portion. An LED electrode electrically connects the first LED to the second LED. The cantilever portion extends in a direction different from the base portion or a length of the cantilever portion is less than a distance between the emission portions of the first and second LEDs.

1-27. (canceled)
A multi-LED component structure, comprising:
- a component substrate;
- a first multi-LED native substrate disposed on the component substrate, the first multi-LED native substrate having a first LED and a separate second LED disposed thereon, wherein the first LED and the second LED are native to the first multi-LED native substrate and electrically connected;
- and
- a second multi-LED native substrate having a third LED and a separate fourth LED disposed thereon, the third LED and the fourth LED are native to the second multi-LED native substrate and electrically connected,
- wherein the first LED, the second LED, the third LED, and the fourth LED are electrically connected to a common electrical connection.
(canceled)
A method of making a multi-LED structure, the method comprising:
- providing a multi-LED native substrate;
- disposing semiconductor layers on the multi-LED native substrate;
- patterning the semiconductor layers to form spatially separated semiconductor portions, the semiconductor portions defining at least a first LED and a second LED separate from the first LED, the first LED and the second LED each comprising (i) a first layer having a cantilever portion and a base portion, and (ii) a second emission layer disposed only over the base portion of the first layer;
- and
- disposing an LED electrode on at least a portion of the multi-LED native substrate or a non-semiconductor structure in the semiconductor layer, the LED electrode electrically connecting the first LED to the second LED,
- wherein
- (i) the cantilever portion of the first LED extends in a first direction and the base portion of the first LED extends in a second direction different from the first direction,
- (ii) the cantilever portion of the first LED has a first cantilever length, the cantilever portion of the second LED has a second cantilever length, and an LED emission separation distance between the emission portion of the first LED and the emission portion of the second LED is less than or equal to the first cantilever length and less than or equal to the second cantilever length, or
- (iii) both (i) and (ii).
