Solid imaging device and portable information terminal device having plural pixels being shielded and not shielded from light

摘要

According to one embodiment, a solid imaging device includes an imaging substrate, a light-shielding member and a AD conversion circuits. The imaging substrate is two-dimensionally arranged with a plurality of pixels. The plurality of pixels have a top face formed with an optoelectronic conversion element for converting incident light into an electric charge and storing it and a back face opposite to the top faces. The imaging substrate is formed with a top face by the top face of the plurality of pixels and formed with a back face by the back face of the plurality of pixels. The light-shielding member is provided on the top face side of the imaging substrate. The AD conversion circuits is formed on the back face of the pixels shielded from the light.
