Abstract

PURPOSE:To prevent an erroneous operation due to an erroneous operation and parasitic capacity caused by a light by providing a conductive light incident preventing insulating film only on a region of a predetermined circuit in an IC device in which part of many semiconductor elements is of an optical sensitive element. CONSTITUTION:A conductive light incident preventing insulating film 4 is provided only on an analog circuit and a dynamic type digital circuit 2 on a region except a photodetecting region of a one-chip IC device having photodetectors 1 to prevent a leakage current from generating due to a light, thereby performing a stable analog operation. On the other hand, since a digital circuit 3 does not have a film 2, a parasitic capacity through the film 2 does not occur. According to this configuration, it can prevent an erroneous operation due to the light and to a parasitic capacity to perform stable operation and high speed.
