Abstract:
In at least one embodiment, a Geiger-mode avalanche photodiode, including a semiconductor body, is provided. The semiconductor body includes a semiconductive structure and a front epitaxial layer on the semiconductive structure. The front epitaxial layer has a first conductivity type. An anode region having a second conductivity type that is different from the first conductivity type extends into the front epitaxial layer. The photodiode further includes a plurality of gettering regions in the semiconductive structure.
