Patent ID: 11769839

Abstract:
A stacked III-V semiconductor diode comprising or consisting of GaAs with a highly n-doped cathode layer, a highly p-doped anode layer and a drift region arranged between the cathode layer and the anode layer, wherein the drift region has a low n-doped drift layer and a low p-doped drift layer, the n-doped drift layer is arranged between the p-doped drift layer and the cathode layer, both drift layers each have a layer thickness of at least 5 μm and, along the respective layer thickness, have a dopant concentration maximum of not more than 8·1015 cm−3, the dopant concentration maxima of the two drift layers have a ratio of 0.1 to 10 to each other and a ratio of the layer thickness of the n-doped drift layer to the layer thickness of the p-doped drift layer is between 0.5 and 3.
