Abstract:
The present disclosure relates to a solid state image sensor, a fabrication method, and an electronic apparatus, which enable to efficiently provide trench structures, which surrounds respective pixel sections of the solid state image sensor, and through-electrodes side by side. A solid state image sensor according to a first aspect of the present disclosure includes photoelectric conversion sections formed in respective pixel sections of a semiconductor substrate, trench structures defined by walls of insulating films formed in a depth direction of the semiconductor substrate and surrounding the respective pixel sections, and through-electrodes formed through the semiconductor substrate at positions overlapping the respective trench structures. The present disclosure can be applied, for example, to back-side illumination CMOS image sensors.

Claim (Index 16):
An electronic apparatus with a solid state image sensor mounted thereon, the solid state image sensor comprising:\n photoelectric conversion sections formed in respective pixel sections of a semiconductor substrate; trench structures defined by walls of insulating films formed in a depth direction of the semiconductor substrate and surrounding the respective pixel sections; and through-electrodes formed through the semiconductor substrate at positions overlapping the respective trench structures, wherein the through-electrodes are each formed of a first conductive portion, which is formed from one side of the semiconductor substrate, and a second conductive portion, which is formed from an opposite side of the semiconductor substrate, connected with each other.
