Abstract:
1. A semiconductor light emitting device comprising: a transparent substrate; a first conductivity type nitride semiconductor layer formed above said transparent substrate; a nitride semiconductor light emission layer formed above said first conductivity type nitride semiconductor layer; a second conductivity type nitride semiconductor layer formed above said nitride semiconductor light emission layer, the second conductivity type being opposite to the first conductivity type; recess regions extending through said second conductivity type nitride semiconductor layer and said nitride semiconductor light emission layer and extending through a partial thickness of said first conductivity type nitride semiconductor layer to expose said first conductivity type nitride semiconductor layer at bottoms of the recess regions, said recess regions defining a plurality of mesa active regions and mesa electrode pull-up regions, each of said mesa active regions and said mesa electrode pull-up regions comprising a portion of said first conductivity type nitride semiconductor layer, a portion of said nitride semiconductor light emission layer, and a portion of said second conductivity type nitride semiconductor layer; a first electrode including a first ohmic electrode portion formed on said first conductivity type nitride semiconductor layer in said recess regions surrounding said plurality of mesa active regions, and first pad electrode portions that are continuous with said first ohmic electrode portion and that extend to said mesa electrode pull-up regions; a second ohmic electrode formed on the portion of said second conductivity type nitride semiconductor layer of each of said plurality of mesa active regions; and a support substrate disposed opposite to said transparent substrate, said support substrate including first conductive connection members connected to and facing said first pad electrode portions and second conductive connection members connected to and facing said second ohmic electrodes.
