Semiconductor light emitting device and method of manufacturing the same

A semiconductor light emitting device, comprising:

• a substrate having an uneven surface, the uneven surface having convex portions;
• a first conductivity type semiconductor layer, an active layer, and a second conductivity type semiconductor layer, which are sequentially laminated onto the uneven surface of the substrate;
• and
• a silica particle layer having a plurality of silica particles disposed only on convex portions of the uneven surface, wherein:
• the silica particles are directly in contact with the convex portions of the uneven surface,
• the silica particle layer is a monolayer to reflect light from the active layer,
• the plurality of silica particles have a spherical shape, and
• the convex portions have a cylindrical shape.
