Abstract

The invention is directed to an avalanche photodiode containing a substrate and semiconductor layers with various electro-physical properties having common interfaces both between themselves and with the substrate. The avalanche photodiode may be characterized by the presence in the device of at least one matrix consisting of separate solid-state areas with enhanced conductivity surrounded by semiconductor material with the same type of conductivity. The solid-state areas are located between two additional semiconductor layers, which have higher conductivity in comparison to the semiconductor layers with which they have common interfaces. The solid-state areas are generally made of the same material as the semiconductor layers surrounding them but with conductivity type that is opposite with respect to them. The solid-state areas may be made of a semiconductor with a narrow forbidden zone with respect to the semiconductor layers with which they have common interfaces.
