Abstract:
1. A light emitting apparatus comprising: a GaN substrate which is a nitride semiconductor substrate; an n-type Al a p-type Al a light emitting layer, at said first main surface side, placed between said n-type Al said GaN substrate includes plate-shape crystal inversion domains extending continuously in a plane shape in the thick-wise direction and a single direction within the GaN substrate surface, the plate-shape crystal inversion domains within the GaN substrate surface and plate-shape crystal inversion domains propagated to said n-type and p-type nitride semiconductor layers formed on said GaN substrate are removed from said p-type nitride semiconductor layers side through said n-type nitride semiconductor layers to a position inside of said GaN substrate, and in contact with the left p-type nitride semiconductor layers, p-electrodes are provided on the respective p-type nitride semiconductor layers.
