Abstract
The detection device includes a semiconductor substrate of a first conductivity type. A matrix of photodiodes organized along a first organization axis is formed on the substrate. Each photodiode is at least partially formed in the substrate. A peripheral biasing ring is formed around the photodiode matrix. The biasing ring is connected to a bias voltage generator. An electrically conducting contact is connected to the substrate and arranged between two photodiodes on the first organization axis. The distance separating the contact from each of the two photodiodes is equal to the distance separating two adjacent photodiodes along the first organization axis. The contact is connected to the bias voltage generator.
