Charge-coupled device

A charge-coupled device having a semiconductor body comprising a surface-adjoining semiconductor layer substantially of a first conductivity type, said semiconductor layer having a charge transport channel for storage and transport of information representing charge packets, said charge packets corresponding to a second conductivity type opposite to that of the first conductivity type, a switchable connection, said charge transport channel having at least two segments which can be connected in series with each other by said switchable connection, by means of which a charge packet that has been transported through the first segment of the charge transport channel may be transferred to the second segment for further charge transport through the second segment, the switchable connection comprising a first zone of said second conductivity type and constituting an output diode for the first segment, a second zone of the second conductivity type constituting an input diode for the second segment, and a switch having at least one main electrode connected to one of these zones.
