Patent ID: 8455284

Claim:
A method of manufacturing a group III nitride nanorod light emitting device, the method comprising steps of: preparing a substrate; forming an insulating film including one or more openings exposing parts of the substrate on the substrate; growing first conductive group III nitride nanorod seed layers on parts of the substrate exposed through the openings, by supplying a group III source gas and a nitrogen (N) source gas; growing first conductive group III nitride nanorods on the first conductive group III nitride nanorod seed layers by supplying the group III source gas, an impurity source gas and the N source gas; forming an active layer on a surface of each of the first conductive group III nitride nanorods; and forming a second conductive nitride semiconductor layer on the active layer, wherein: the step of growing first conductive group III nitride nanorods includes a first growth process forming middle portions of the first conductive group III nitride nanorods on the first conductive group III nitride nanorod seed layers and a second growth process forming end portions of the first conductive group III nitride nanorods, and the group III source gas and an impurity source gas are supplied in a pulse mode during the step of growing first conductive group III nitride nanorods, while the N source gas is continuously supplied without a pulse mode during at least the first growth process; the impurity source gas is silane (SiH 4 ); wherein the group III source gas is trimethyl gallium (TMGa); and wherein the N source gas is ammonia (NH 3 ).
