Claim:
1. A method of manufacturing a nanostructure semiconductor light emitting device, the method comprising: preparing a mask layer by sequentially forming a first insulating layer and a second insulating layer on a base layer configured of a first conductivity-type semiconductor; forming a plurality of openings penetrating through the mask layer in a thickness direction of the mask layer; growing a plurality of nanorods configured of the first conductivity-type semiconductor in the plurality of openings formed in the mask layer; exposing the plurality of nanorods by removing the second insulating layer; forming a plurality of nanacores by re-growing the plurality of nanorods; and forming a plurality of nanoscale light emitting structures by sequentially growing an active layer and a second conductivity-type semiconductor layer on surfaces of the plurality of nanocores, wherein the plurality of openings respectively include a mold region located in the second insulating layer and defining a shape of side surfaces of the plurality of nanorods, wherein the mold region includes at least one curved portion of which an inclination of a side surface varies according to proximity to the first insulating layer, and wherein the mold region comprises one second-type curved portion in which an inclination of a side surface is altered so that a width of the opening is first increased and then decreased according to proximity to the first insulating layer, and an inclination portion contacting the first insulating layer and having an inclined side surface so that a width of the opening is decreased according to proximity to the first insulating layer.
