Assignee: PMDTECHNOLOGIES AG
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 4:
5. A light propagation time pixel comprising modulation gates and integration nodes disposed at a top side of a photosensitive semiconductor region,
wherein the photosensitive semiconductor region is formed as n-epitaxy and laterally and/or at its corners delimited by p-doped vertical p-structures,
wherein a buried layer with a p-doping adjoins a bottom side of the photosensitive semiconductor region,
wherein the vertical p-structures are in electrical contact with the buried layer, in which on the top side of the light propagation time pixel laterally to the photosensitive region p-doped regions are arranged and configured as p-wells and the p-structures are in electrical contact with the p-wells.
