ABSTRACT:
The image pickup system includes: MOS sensors arranged in an image pickup region of a semiconductor substrate in the form of a matrix and having photoelectric transfer layers; a peripheral circuit part formed in a region of the semiconductor substrate except for the image pickup region and having a driving circuit for driving the MOS sensors and a signal processing circuit for processing output signals from the MOS sensors; and microlenses, formed on the photoelectric transfer layers via a first insulating film, for condensing picture signals on the photoelectric transfer layers, wherein the driving circuit and the signal processing circuit in the peripheral circuit part are covered by a second insulating film, and the distance between the surface of the first insulating film and the semiconductor substrate is shorter than the distance between the surface of a second insulating film and the semiconductor substrate.
