Abstract

A semiconductor laminating portion including a light emitting layer forming portion having at least an n-type layer and a p-type layer is formed on a semiconductor substrate. A current blocking layer is partially formed on its surface. A current diffusing electrode is formed on the entire surface thereof. A bonding electrode is formed thereon. The semiconductor laminating portion and the current diffusing electrode are separated into light emitting unit portions A, electrode pad portion B, and connecting portions C for connecting between electrode pad portion B and light emitting unit portions A or between two of the light emitting unit portions A, and the semiconductor laminating portion between the light emitting unit portions A is removed through etching to make clearances except for connecting portions C. The bonding electrode is formed on electrode pad portion B.

Dependent claims

A semiconductor light emitting device comprising:

a semiconductor substrate;
a semiconductor laminating portion formed on said semiconductor substrate, said semiconductor laminating portion including a light emitting layer forming portion having at least an n-type layer and a p-type layer;
a current diffusing electrode formed on said semiconductor laminating portion, said current diffusing electrode exhibiting translucency and electric conductivity;
a bonding electrode formed on a part of said current diffusing electrode;
and
an electrode formed on a rear surface of said semiconductor substrate,
wherein said semiconductor laminating portion and said current diffusing electrode are separated into a plurality of light emitting unit portions, an electrode pad portion, and connecting portions for connecting between said electrode pad portion and said light emitting unit portions or between two of said light emitting unit portions, and
wherein said bonding electrode is provided on said electrode pad portion, and said electrode pad portion is formed so as to make said light emitting layer forming portion in said electrode pad portion be nonluminous.
