Claim Text:
1. A method of manufacturing a nanostructure semiconductor light emitting device, the method comprising: providing a base layer formed of a first conductivity-type semiconductor; forming a mask including an etch stop layer on the base layer; forming a plurality of openings with regions of the base layer exposed therethrough, in the mask; forming a plurality of nanocores by growing the first conductivity-type semiconductor on the exposed regions of the base layer to fill the plurality of openings, entire side surfaces of the plurality of the nanocores being defined by a shape of the openings; partially removing the mask using the etch stop layer to expose side portions of the plurality of nanocores; regrowing the plurality of nanocores by supplying a source gas for the first conductivity-type semiconductor; and sequentially growing an active layer and a second conductivity-type semiconductor layer on surfaces of the plurality of nanocores.
