Abstract
The invention provides a method for fabricating a light-emitting diode with uniform color temperature, comprising the steps of: forming a plurality of light-emitting diodes on a wafer; obtaining the light emission wavelengths of the light-emitting diodes on the wafer; and forming different doses of phosphor on the corresponding light-emitting diode on the wafer according to the light emission wavelengths of respective light-emitting diodes. Finally, the light-emitting diodes on the wafer emit light with uniform color temperature.
