Method of making light emitting diodes (LEDs) with improved light extraction by roughening
Methods are provided for fabricating a semiconductor light-emitting diode (LED) device by providing an LED wafer assembly having an LED stack and selectively roughening and/or texturing a light-emitting surface of the LED stack's n-doped layer. In this manner, light extraction from the LED device is improved.
