ABSTRACT:
A semiconductor device having a number of series-arranged photosensitive cells which are provided on a common substrate of a first conductivity type and which are separated by grooves extending down to the substrate. The cells consist of first regions of a first conductivity type which form planar photosensitive junctions with second regions of the second conductivity type. According to the invention, a highly doped layer of the second conductivity type is present between the substrate and the second region and each photosensitive cell is provided, along at least a part of its circumference, with a highly doped semiconductor zone of the second conductivity type which extends along the wall of the groove down to the highly doped layer and is separated from the adjacent cell by the substrate.
