  • Light emitting diode with at least two light emitting zones and method for manufacture
    Publication number: 20070012240
    Abstract: A light emitting diode includes a first light emitting zone and a second light emitting zone. A defect propagation confinement mechanism is disposed in relation to the first light emitting zone and the second light emitting zone.
