CHARGE-COUPLED DEVICE Russian patent published in 1995 - IPC

FIELD: photoelectric transducers. SUBSTANCE: device has semiconductor substrate with three-dimensional charge carrier channel, insulating layer, and outlet electrode. Connected to the latter directly or through transistor switch is additional electrode placed on same insulating layer. Introduced into semiconductor substrate, under additional electrode, is diffusion area of polarity opposite to that of substrate at alloying admixture thickness and concentration same as in three-dimensional charge carrier channel; diffusion area has separate lead; additional electrode is placed inside diffusion area circuit. EFFECT: provision for stepless control of conversion of read-out signals into output voltage. 2 cl, 3 dwg
