Abstract:
A photoreceiver cell with separation of color components of light incident to its surface, formed in a silicon substrate of the conductivity of the first type with an ohmic contact and comprising: the first, second and third regions, which have mutual positioning and configuration, which provide formation of the first and the second channels for diffusion of the secondary charge carriers generated in the substrate regions located under the first and the second potential barriers to the first and the third p-n junctions respectively; in this case, the length of the channels does not exceed the diffusion length of the secondary charge carriers. Some embodiments provide increased spatial resolution of the projected image and its dynamic range. Some embodiments provide small photo-cell area. Some embodiments are used in multielement photoreceivers for video cameras and digital cameras.
