PHOTODETECTOR WITH VERTICAL COLOUR SEPARATION AND VERTICAL-HORIZONTAL CHARGE TRANSFER Russian patent published in 2010 - IPC H01L27/146 

FIELD: physics; photography.

SUBSTANCE: invention relates to machine vision equipment and can be used in multi-spectral photodetector arrays, particularly for converting high format and high pixel density colour images to electrical signals in photographic cameras and video cameras. According to the invention, in a known device of a photodetector there is provision for part of an electrical circuit designed for vertical reading, making cells in form of a gate electrode, forming the surface region of a first group when storage or reading voltage is applied across it for horizontal movement of charges to an amplifier, making an electrical circuit for horizontal reading in form of CCD bulk channels lying outside vertical channels and illumination zones, where the CCD bulk channels contain phase gates connected to phase buses, and circuits for input of charges for restoring initial potential in cells after reading, making one or more selection lines parallel each CCD channel, where the selection lines are successively connected to selection gates which realise charge coupling of the CCD channel with surface regions formed under gates of electrodes of cells.

EFFECT: increase in the signal being read given an extremely small cell area.
