Abstract:
The invention relates to photosensitive semiconductor devices and, more particularly, to linear arrays having several parallel rows of photoconductive points and operating in the integration and charge carry mode. In particular, the object of the invention is to reduce a smearing effect.The device of the invention comprises a photosensitive surface (SP) divided into photosensitive surface elements (SI1 to SMn) placed in rows (L1 to Ln) and in columns (C1 to CM). Each column forms a shift register that ends in a storage space (CS1 to CSM) of a readout register (RL) formed by a shift register of the charge transfer type: readout register (RL) being on same semiconductor substrate (10) as photosensitive surface (SP) the device includes.According to a feature of the invention, the device an intermediate zone (ZI) protected from light used to make a separation distance (DS) between photosensitive surface (SP) and readout register (RL).
