This study has been carried out to determine the optimal process conditions of AZO:H2 thin films for the maximization

of the transmittance of a blue GaN light-emitting diode (LED) with a wavelength of 470 nm. The Al-doped zinc oxide

(AZO):H2 thin films were deposited on a sapphire substrate by radio-frequency magnetron sputtering system with

varying substrate temperatures, working pressures and annealing temperatures temperature, working pressure and

annealing imposed on a AZO (2wt% Al2O3) ceramic target. The effect of these variables was investigated in order to

improve the light extraction efficiency of the LED. As a result, the (002)-oriented peak was found in all the AZO:H2 thin

films. The lowest resistivity and the best transmittance at a wavelength of 470 nm was found to be 4.774 × 10-4 Ωcm

and 92% at a substrate temperature of 500°C, working pressure of 7 mTorr and annealing temperature of 400°C. The

transmittance of the AZO:H2 thin film for the Blue GaN LED was improved by approximately 13% relative to that of a

ITO thin film (T = 79%).
