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

Claim 17:
18. A diode, comprising:
a stack of functional layers including a first semiconductor layer, a second semiconductor layer, and a light emitting layer located between the first semiconductor layer and the second semiconductor layer;
a first electrode and a second electrode located at the same side of the first semiconductor layer, wherein the first electrode is electrically connected to the first semiconductor layer and the second electrode is electrically connected to the second semiconductor layer; and
a current limiting region or a current blocking region covering at least a portion of the first semiconductor layer, the light emitting layer or the second semiconductor layer;
wherein a first width of the first electrode away from the first semiconductor layer is wider than a second width of the first electrode near the first semiconductor layer;
wherein a third width of the second electrode away from the first semiconductor layer is equal to or narrower than the first width;
wherein at least a portion of the current limiting region or the current blocking region is formed about an outer edge of the diode.
