Assignee: VISIONLABS CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A diode array, comprising:
a substrate; and
a plurality of light emitting diodes disposed on the substrate and arranged in an array, wherein each of the light emitting diodes includes a stack of functional layers comprising a first semiconductor layer, a second semiconductor layer, and a light emitting layer located between the first semiconductor layer and the second semiconductor layer,
wherein at least one of the light emitting diodes includes:
a first current limiting region covering at least a portion of the first semiconductor layer, the light emitting layer or the second semiconductor layer;
a first electrode electrically connected to the first semiconductor layer; and
a second electrode electrically connected to the second semiconductor layer,
wherein the first electrode and the second electrode are disposed at the same side of the first semiconductor layer;
wherein a first width of the first electrode near the substrate is wider than a second width of the first electrode near the first semiconductor layer;
wherein a third width of the second electrode near the substrate is equal to or narrower than the first width;
wherein at least a portion of the first current limiting region is formed about an outer edge of the at least one of the light emitting diodes.
