PHB. 32,544. ABSTRACT A charge coupled circuit arrangement for converting an electromagnetic radiation pattern in a certain wavelength band into electrical signals comprises a semiconductor body having a first layer-shaped part and an adjoining second layer- shaped part contiguous with the first layer-shaped part. The first layer-shaped part consists of semiconductor material hav- ing a charge transfer register for transferring, in the first layer, carriers representative of pattern information. The second layer-shaped part consists of a photosensitive semicon- ductor material capable of yielding free charge carriers when subjected to radiation of a certain wavelength band. The circuit arrangement connected to the device includes a means to cause locally, at positions associated-with storage sites in the first layer-shaped part, the punch-through to the second layer-shaped part of a depletion region formed in the first layer-shaped part. This enables the direct introduction of radiation generated free charge carriers characteristic of a single conductivity type from the second layer-shaped part into the storage sites, these storage sites being associated with the charge transfer register.
