ABSTRACT:
An integrated circuit device comprising a semiconductor substrate of one conductivity type and provided with a circuit element capable of dynamically holding electric charges and another circuit element having p-n junctions, characterized in that at least one part of that region of the substrate which surrounds the circuit element capable of holding the above-mentioned charges is formed of an absorption region having an opposite conductivity type to that of the substrate; and that said absorption region is impressed with the highest or substantially highest level of voltage among those impressed on the circuits included in the integrated circuit device, thereby enabling the absorption region to catch minority carriers injected from said another circuit element into the substrate.
