IMAGE CAPTURING DEVICE AND IMAGE CAPTURING SYSTEM Russian patent published in 2014 - IPC H01L27/14 

FIELD: physics, photography.

SUBSTANCE: invention relates to a photoelectric converter. In a photoelectric converter which adds together signals from a plurality of photocells included in photoelectric conversion blocks, each of the plurality of photocells includes a first semiconductor region of a first conductivity type which accumulates signal carriers. The first semiconductor regions included in photocells, which are included in each of the photoelectric conversion blocks and are placed in immediate proximity to each other, accommodate a second semiconductor region of a second conductivity type between each other. The height of the potential barrier for signal carriers generated in a defined region of the second semiconductor region is less than that for signal carriers generated in a third semiconductor region located between each of the first semiconductor regions and a drain region for excess charges of the first conductivity type.

EFFECT: invention enables to obtain the necessary signal in a situation when one signal is received using signals from a plurality of photocells by creating an insulation structure between photocells.
