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 10):
A fabrication method of a solid state image sensor, 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, the trench structures being each formed from straight portions and crosspoints where the straight portions intersect one another, the through-electrodes being each formed at a position that overlaps one of the straight portions of the corresponding trench structure, wherein the straight portions and the crosspoints of each trench structure and the associated through-electrode have the following relationship in layout dimension: through-electrode>crosspoints of trench structure>straight portions of trench structure, and the straight portions and the crosspoints of each trench structure and the associated through-electrode have the following relationship in depth: through-electrode>crosspoints of trench structure>straight portions of trench structure.
