    Abstract: 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.

    Abstract: A lateral single-photon avalanche diode comprises a semiconductor body (1) of a first type of conductivity which includes a base layer (10), a first further layer (11) on the base layer and a second further layer (12) 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. Thereby, the high electric field region or avalanche region is essentially confined to the first further layer (11). A doped region (5) 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 (3, 4) are electrically connected to the first further layer and the doped region, respectively. The doped region can be produced by filling a trench (19) with doped polysilicon.

    Abstract: The photodiode device comprises a doped region (2) contiguous with a contact region (3) of the same conductivity type located at the substrate surface (1'), an appertaining anode or cathode connection (7, 11), a further contact region (5) of an opposite conductivity type at the substrate surface, and a further anode or cathode connection (8, 12). The contact region (3) is arranged at least on opposite sides of an active area of the substrate surface that covers the further contact region (5). A lateral pn junction (16) and an associated space charge region is formed at the substrate surface by a boundary of one of the contact regions, the boundary facing the other contact region. A field electrode (6) is arranged above the lateral pn junction, separated from the lateral pn junction by a dielectric material (10), and is provided with a further electrical connection (9, 13) separate from the anode and cathode connections. By the field electrode (6), the space charge region at the surface (1') is reduced and the peripheral dark current of the photodiode decreases considerably.
