First Claim
Patent Images
1. A light-emitting diode comprising:
- an epitaxial substrate;
a light-emitting unit including a lower semiconductor layer, and at least two epitaxial units that are separately formed on said lower semiconductor layer, said epitaxial units cooperating with said lower semiconductor layer to define two light-emitting sources that are capable of emitting different colors of light; and
an electrode unit including a first electrode which is formed on an exposed portion of said lower semiconductor layer exposed from said epitaxial units, and at least two second electrodes each of which is formed on a corresponding one of said epitaxial units.

8. A method for forming a light-emitting diode comprising:
-
(a) forming over an epitaxial substrate a lower semiconductor layer; (b) forming a first epitaxial unit on the lower semiconductor layer, the first epitaxial unit and the lower semiconductor layer defining a first light-emitting source; (c) forming a second epitaxial unit on the lower semiconductor layer in a manner that the first and second epitaxial units are spaced apart from each other, the second epitaxial unit and the lower semiconductor layer defining a second light-emitting source, the first and second light-emitting sources being capable of emitting different colors of light; and (d) forming a first electrode on an exposed portion of the lower semiconductor layer exposed from the first and second epitaxial units, and forming at least two second electrodes respectively on the first and second epitaxial units opposite to the lower semiconductor layer. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
