A common cathode 3D RGB light emitting diode chip is produced using through silicon via (TSV) technology. The experimental results show that the diameter, the length and the depth of the Si via are about 140 μm, 50 nm and 320 μm, respectively. The Cu is uniform with a high density in each TSV and the average resistance is about 0.61 m. The measurement of the thermal images shows that the temperature at which a 3D LED (105 C) operates is lower than that for a LED (120 C) when the two devices are injected with a 20 mA current. Using 20 mA current injections, the current-voltage (I-V) output for 3D RGB LED chips is on average 218.84 mW/W, 186.65 mW/W and 324.49 mW/W.
