Abstract:
1. A method for manufacturing a white light emitting diode, comprising the steps of: (a) preparing a conductive substrate with a light transmitting property having a first surface divided into first and second areas, and a second surface being opposed to the first surface; (b) forming a first emitting unit by sequentially stacking a first clad layer, a first active area, and a second clad layer at the first area of the conductive substrate; (c) forming a second emitting unit by sequentially stacking a third clad layer, a second active area emitting light with a wavelength to be combined with light emitted from the first active area into white light, and a fourth clad layer at the second area of the conductive substrate; and (d) forming a first electrode on the second surface of the conductive substrate, a second electrode on the second clad layer, and a third electrode on the fourth clad layer.
