Abstract:
1. A solid-state imaging device comprising: a pixel region which is configured such that a photoelectric conversion unit and a signal scanning circuit unit are included in a semiconductor substrate, and a matrix of unit pixels is disposed; and a driving circuit region which is configured such that a device driving circuit for driving the signal scanning circuit unit is disposed on the semiconductor substrate, wherein the photoelectric conversion unit is provided on a back surface side of the semiconductor substrate, which is opposite to a front surface of the semiconductor substrate where the signal scanning circuit unit is formed, and the pixel region includes an insulation film which surrounds the photoelectric conversion unit in the unit pixel, which is formed through the semiconductor substrate, and which defines a device isolation region, and wherein the insulation film is disposed in a discontinuous hole-like plan-view shape in a manner to surround a boundary part with the unit pixel that neighbors.
