Beschreibung
Zusammenfassung:The lateral single-photon avalanche diode comprises a semiconductor body (1, 2) comprising a semiconductor material of a first type of electric conductivity, a trench (3) in the semiconductor body, and anode and cathode terminals (5, 6). A junction region (14) of the first type of electric conductivity is located near the sidewall (38) of the trench, and the electric conductivity is higher in the junction region than at a farther distance from the sidewall. A semiconductor layer (4) of an opposite second type of electric conductivity is arranged at the sidewall of the trench adjacent to the junction region. The anode and cathode terminals are electrically connected with the semiconductor layer and with the junction region, respectively. The junction region (14) may be formed by a sidewall implantation.
