Patent ID: 7138665

Claim:
A light emitting element comprising: a substrate; a light emitting layer formed on said substrate to emit light, wherein said light emitting layer includes a first semiconductor layer of a first conductivity type, an active layer formed on said first semiconductor layer to emit the light and a second semiconductor layer of a second conductivity type formed on said active layer; a first electrode contacting said second semiconductor layer; and a second electrode contacting said first semiconductor layer, said first electrode comprising: an ohmic layer in ohmic contact with said second semiconductor layer; a first barrier layer formed on said ohmic layer; a light reflecting layer formed on said first barrier layer; a second barrier layer formed on said light reflecting layer; and an overcoat electrode for mounting formed on said second barrier layer, wherein said ohmic layer is made of a plurality of islands arranged into array and each of said plurality of islands has a hemispherical shape.
