Patent ID: 8659107

Claim:
A radiation receiver comprising: a first active region and a second active region disposed in a semiconductor body, the second active region spaced vertically from the first active region, the first and second active regions each provided for the detection of radiation, wherein the first active region and the second active region are each arranged between a barrier layer and a counter barrier layer, wherein the barrier layer and the counter barrier layer have mutually different conduction types; a tunnel region arranged between the first active region and the second active region, wherein the tunnel region comprises a first tunnel layer and a second tunnel layer having mutually different conduction types, wherein the first tunnel layer and the second tunnel layer project in lateral direction beyond the first active region; and a contact between the first active region and the second active region for external electrical contacting of the semiconductor body the tunnel region being electrically connected with the contact, wherein the contact is arranged directly on a portion of the tunnel region that projects laterally beyond the first active region.
