Abstract
The disclosure relates to a light propagation time pixel, comprising modulation gates and integration nodes which are arranged on the upper face of a photosensitive semiconductor region. The photosensitive semiconductor region is designed as an N-epitaxy and is delimited laterally and/or at the corners by p-doped vertical p-structures. A buried layer with a p-doping adjoins the lower face of the photosensitive semiconductor region, and the vertical p-structures are in electric contact with the buried layer.
