Abstract
According to one embodiment, a back side illumination solid-state image sensing device which comprises a pixel region where a plurality of pixels each including a photoelectric converter and a signal scanning circuit are arranged on a semiconductor substrate, and in which a light illumination surface is formed on a substrate surface opposite to a surface of the semiconductor substrate on which the signal scanning circuit is formed, includes a silicon oxide film formed on the semiconductor substrate on the light illumination surface side, a p-type amorphous silicon compound layer formed on the silicon oxide film, and a hole storage layer formed by the p-type amorphous silicon compound layer near an interface between the semiconductor substrate on the light illumination surface side and the silicon oxide film.
