Frame-transfer charge-coupled image sensor device having channel sounding regions below light-admitting windows

摘要

A charge-coupled image sensor device of the frame-transfer type has an electrode system through which windows (14) allow light to enter the device. One group of electrodes (15 and 16 ) extends transverse to charge transport channels (9 or 11) in the device. Another group of electrodes (18) extends parallel to the channels. Channel bounding regions (12) that electrically separate the channels lie below substantially the entire areas of the windows.
