Abstract:
This invention provides a nitride semiconductor light emitting device in which current concentration is suppressed without excessively increasing resistance at a low cost without increasing a manufacturing process. The planar shape of a mesa portion configuring a nitride semiconductor light emitting device is a shape containing a convex-shaped tip portion  352 b  formed by a curved line or a plurality of straight lines and a base portion  352 a  continuous to the convex-shaped tip portion  352 b , in which an obtuse angle is formed by adjacent two straight lines in the convex-shaped tip portion formed by the plurality of straight lines. The first electrode layer  4  has visible outlines  411  and  412  along a visible outline  302  of the mesa portion through a gap  9  in planar view. The relationship between a gap W 1  in the convex-shaped tip portion  352 b  and a gap W 2  in the base portion  352 a  is W 1 >W 2.

Claim (Index 3):
A nitride semiconductor light emitting device comprising:\n a substrate; a nitride semiconductor laminate containing a first nitride semiconductor layer having a first conductivity type formed on the substrate, a nitride semiconductor light emitting layer formed on the first nitride semiconductor layer, and a second conductivity type second nitride semiconductor layer formed on the nitride semiconductor light emitting layer, the nitride semiconductor light emitting layer and the second nitride semiconductor layer being formed in one part on the first nitride semiconductor layer to configure a mesa portion; a first electrode layer formed on the first nitride semiconductor layer except the one part; and a second electrode layer formed on the second nitride semiconductor layer, wherein a planar shape of the mesa portion is a shape containing a convex-shaped tip portion formed by a curved line or a plurality of straight lines and a base portion continuous to the convex-shaped tip portion, the convex-shaped tip portion formed by the plurality of straight lines having an obtuse angle formed by adjacent two straight lines, and an angle \u03b8 (\u226490\u00b0) defined by a cross angle between a side surface of the mesa portion facing the first electrode layer and a surface parallel to a surface of the substrate on which the first nitride semiconductor layer is formed is smaller in the convex-shaped tip portion than in the base portion.
