Abstract
Semiconductor light-emitting devices are provided. The semiconductor light-emitting devices include a substrate and a crystal layer selectively grown thereon at least a portion of the crystal layer is oriented along a plane that slants to or diagonally intersect a principal plane of orientation associated with the substrate thereby for example, enhancing crystal properties, preventing threading dislocations, and facilitating device miniaturization and separation during manufacturing and use thereof.
Claims1
A lighting system comprising:
- a plurality of semiconductor light-emitting device arranged so as to emit light in response to a signal, each of the semiconductor light-emitting devices comprising a substrate including a substrate surface positioned along a surface plane, a crystal layer including a crystal surface oriented along a crystal surface plane diagonally intersecting the substrate surface plane, and a first conductive layer, an active layer, and a second conductive layer each formed along at least a portion of the crystal surface, wherein the crystal surface plane comprises a plane having a plane orientation inclined at an angle ranging from about 5 to about 6 degrees with respect to at least one of a S-plane and a (11-22) plane.
