Abstract :
A process for fabrication of flip chip LEDs based on SnO2-GaN wafer bonding is reported. Typical LED characteristics have been measured and no detrimental effect of the bonding interface has been observed. The forward voltage at 20 mA is 3.96 V and differential resistance at 100 mA is as low as 16 Ω.
