The light extraction layer includes: a plurality of cone-shaped parts formed in an array on the light extraction surface, and a plurality of granular parts formed both on a side part of the cone-shaped part and in a space between adjacent cone-shaped parts. A method of manufacturing the semiconductor light emitting device includes: forming a mask having an array pattern on the light extraction layer; and etching the mask and the light extraction layer from above the mask. The etching includes first dry-etching performed until an entirety of the mask is removed and second dry-etching performed to further dry-etch the light extraction layer after the mask is removed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor light emitting device and method of manufacturing semiconductor light emitting device having pattered light extraction surface","description":"A semiconductor light emitting device includes a light extraction layer having a light extraction surface.
