Abstract:
A semiconductor body of a first type of conductivity is formed including a base layer, a first further layer on the base layer and a second further layer on the first further layer. The base layer and the second further layer have an intrinsic doping or a doping concentration that is lower than the doping concentration of the first further layer. A doped region of an opposite second type of conductivity is arranged in the semiconductor body, penetrates the first further layer and extends into the base layer and into the second further layer. Anode and cathode terminals are electrically connected to the first further layer and the doped region, respectively. The doped region can be produced by filling a trench with doped polysilicon.

Claim (Index 10):
A method of producing a lateral single-photon avalanche diode, comprising:\n providing a semiconductor body with a first type of conductivity, including a base layer of semiconductor material, a first further layer of semiconductor material on the base layer and a second further layer of semiconductor material on the first further layer; forming a trench in the semiconductor body, the trench penetrating the second further layer and the first further layer and extending into the base layer; filling the trench with an electrically conductive material doped for a second type of conductivity, which is opposite to the first type of conductivity, thus forming a doped region; and forming anode and cathode terminals, one of the terminals being arranged in the electrically conductive material of the trench and the other one of the terminals being arranged in the semiconductor body outside the trench at a distance from the trench.
