Abstract: An improved line-transfer photosensitive device and particularly a device which operates with a double drive charge comprises on at least one semiconductor substrate a photosensitive region made up of M lines of N photosensitive points. The photosensitive points of the different lines are connected in parallel by means of conductive columns to a line memory which carries out at least the transfer of the signal charges integrated on any one line of the phtosensitive region to a read register consisting of a charge-coupled shift register of the volume transfer type. The line memory is formed on a semiconductor substrate region having an impurity implantation of opposite type with respect to the substrate in order to produce a volume charge transfer. The region in which the line memory is formed has a dopant concentration which is lower than or equal to that of the region in which the shift register is formed.

Abstract: The storage capacity of the photosensitive points is increased during the time interval starting after the evacuation of the parasitic charges from the conductive columns to the memory and finishing by the transfer of signal charges from a row of the columns to the memory. Thus, even the overilluminated photosensitive points do not overflow onto the columns.

Abstract: The present invention concerns an analysis process of a line transfer photosensitive device.The charge-signal and the charge noise transfers from the columns towards the memory have the same duration and are made by using a same training charge, stored in memory, that must be at least sufficient to allow to pass in high inversion at the beginning of the transfer from the columns towards the memory. The transfers of the charge-signal and the charge-noise from the memory towards the read-out register or the drain have the same duration and are made by using training charges at least sufficient to allow to pass in high inversion at the beginning of the transfer. These training charges are read with the charge-signal or collected with the charge-noise.
