Claim Text:
1. A method of manufacturing a core-shell structure semiconductor light emitting device, the method comprising: growing, by using a first conductivity type semiconductor, a plurality of cores on selective portions of a base layer including the first conductivity type semiconductor, such that each of the plurality of cores includes a main part that has a side surface having a first crystal plane in a growth direction and an upper part that has a surface having a second crystal plane different from the first crystal plane; forming a plurality of light emitting core-shell structures by sequentially growing a shell including an active layer and a second conductivity type semiconductor layer on surfaces of the respective cores; forming a contact electrode on a surface of the second conductivity type semiconductor layer; and planarizing a surface of the core-shell structure semiconductor light emitting device in which the contact electrode is disposed, so as to remove a portion of the active layer disposed on the second crystal plane, wherein the growing of the plurality of cores comprises growing at least a group of cores among the plurality of cores to have cross-sectional areas or an interval therebetween different from cross-sectional areas of or an interval between another group of cores among the plurality of cores.
