Patent ID: 7687822

Claim:
A light emitting apparatus comprising: a GaN substrate which is a nitride semiconductor substrate; an n-type Al x Ga 1−x N layer (x is in the range of from 0 to 1) which is an n-type nitride semiconductor layer at a first main surface side of said GaN substrate; a p-type Al x Ga 1−x N layer (x is within the range of from 0 to 1), at said first main surface side, placed more distantly from said GaN substrate than said n-type Al x Ga 1−x N layer; and a light emitting layer, at said first main surface side, placed between said n-type Al x Ga 1 −x N layer and said p-type Al x Ga 1 −x N layer, wherein 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.
