InGaN/GaN blue light emitting diodes (LEDs) prepared on both patterned and conventional sapphire substrates were fabricated. Atomic force microscopy (AFM) images show the micro surface roughness could be observed only from the LEDs prepared on patterned substrates. It was also found that electroluminescence (EL) intensity of LEDs grown on patterned sapphire substrate was about 50% larger than that prepared on conventional sapphire substrates. Reliability of LEDs grown on patterned sapphire substrates was also found to be better.
