Abstract: A transparent conductive layer is deposited between the electrode and the semiconductor diode to spread the current evenly to the diode and to reduce the series resistance. Tin indium oxide can be used as the transparent conductive layer. The transparent conductive layer is particularly applicable to a blue light emitting diode, where InGaN is used as the light emitting layer.
