TWO-DIMENSIONAL PHOTOSENSITIVE SOLID-STATE DEVICE AND IMAGER, USING TRANSFER OF ELECTRICAL CHARGES, COMPRISING SUCH A DEVICE

摘要

A charge transfer photosensitive device, having a plurality of photosensitive zones (20) fabricated on a single conducting substrate, and having N lines and M columns, and insulated from one another. In the photosensitive zones electrical charges are created depending upon light received. Each of these zones is formed by a MOS capacitance (3) and a charge collecting diode (8). A plurality of reading diodes (5) read the charges collected in the photosensitive zones; and a screen grid (4) is placed between the reading diodes (5) and the photosensitive zones (20).
