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 while a current diffusing electrode is formed on the entire surface thereof. The current diffusing electrode is patterned into a plurality of light emitting unit portions (A), electrode pad portion (B), and connecting portions (C) for connecting between the electrode pad portion (B) and the light emitting unit portions (A) or between two of the light emitting unit portions (A), and a part of the semiconductor laminating portion may be etched according to the patterning of the current diffusing electrode. The bonding electrode may be formed on the electrode pad portion (B) which is formed so as to make the light emitting layer forming portion non-luminous.
