Abstract
Embodiments related to controlling of photo-generated charge carriers are described and depicted. At least one embodiment provides a semiconductor substrate comprising a photo-conversion region to convert light into photo-generated charge carriers; a region to accumulate the photo-generated charge carriers; a control electrode structure including a plurality of control electrodes to generate a potential distribution such that the photo-generated carriers are guided towards the region to accumulate the photo-generated charge carriers based on signals applied to the control electrode structure; a non-uniform doping profile in the semiconductor substrate to generate an electric field with vertical field vector components in at least a part of the photo-conversion region.
